RESUMO

The quality of preparations offered in the workplace can vary according to the different segments of food services and may impact the health of the workers. This study aimed to qualitatively assess the food preparation offered to workers in from different food services. A total of 384 preparations were offered to workers in Curitiba City, Brazil. The preparations from three different segments of food services were evaluated: commercial (pilot study), non-commercial, and outsourced, selected for convenience. To identify the preparations, the nutritionist was interviewed, and the production process was monitored. The Score for Qualitative Assessment of Preparations (EAQP) was applied to evaluate the preparations, and they were classified according to their quality: high, intermediate, low, and very low quality. The chi-square and Kruskal-Wallis tests with post-hoc Least Significant Difference (LSD) Test were used. Most of the preparations were of high quality (72.9%), using mainly the unprocessed or minimally processed ingredients. The preparations offered by the non-commercial food service provider had a better mean quality score when compared to other food services (p < 0.01). This study outcome is essential to help food service professionals to decide and choose the ingredients used in the preparations.

RESUMO

BACKGROUND: Poor-quality diets are a major risk factor for noncommunicable diseases. Few studies in Mexico have tested whether higher expenditures are needed to purchase high-quality food. OBJECTIVE: The objective of the study was to assess how dietary quality of food purchases was associated with household food at home expenditures. DESIGN: This study was a secondary analysis of cross-sectional data from the National Household Income and Expenditure Survey (EncuestaNacional de Ingresos y Gastos de los Hogares [ENIGH] 2018). PARTICIPANTS/SETTING: The study included 74 469 households with information on food and beverage purchases in Mexico in 2018. MAIN OUTCOME MEASURES: Quarterly household food at home expenditures by adult equivalent (AE) for all food groups that were scored with the Global Dietary Quality Score (GDQS) for food purchases expressed in dollars/quarterly/AE. STATISTICAL ANALYSES PERFORMED: Adjusted generalized linear models were used to evaluate the association between GDQS for food purchases (expressed in tertiles: low, mid, and high) and quarterly food expenditures. The analyses were performed at the national level by place of residence and income quintile. RESULTS: At the national level, the difference in food expenditures between the high- and the low-GDQS groups was +$13.85/AE. By place of residence, the difference between the high- and the low-GDQS groups was +$17.31/AE in urban and +$5.12/AE in rural areas. For income quintile 1 (lowest), there was a statistical difference of -$4.79/AE and +$43.25 for quintile 5 (highest). CONCLUSIONS: Quality of food purchases can be associated with higher or lower expenditures depending on the specific food purchased. High GDQS is associated with lower expenditures among the lowest-income households as they purchase less expensive options compared with high-income households.

RESUMO

This study aimed to evaluate the influence of films based on chitosan and rosemary extract on the physicochemical, microbiological, and oxidative characteristics of beef. Refrigerated steaks of Longissimus dorsi were distributed in a factorial arrangement (4 × 4) into four treatments consisting of four edible films (control; chitosan; chitosan + 4% rosemary extract; and chitosan + 8% rosemary extract) and four days of aging (0, 2, 4, and 8 days). Incorporating 4% or 8% rosemary extract into the chitosan film improved the characteristics of the films in terms of moisture absorption and elasticity. The edible coatings with chitosan and rosemary extract and the different days of aging increased the tenderness and decreased the lipid oxidation of beef. In addition, the chitosan films containing rosemary extract increased the water-holding capacity and decreased the cooking losses of beef. The films containing 4% and 8% rosemary extract decreased the development of mesophilic and psychrotrophic bacteria and Staphylococcus ssp. in beef. We recommend incorporating 4% rosemary extract into chitosan-based coatings to preserve the quality of refrigerated beef.

RESUMO

Cryostructured gels, better known as cryogels, are a very important emerging class of biomaterials that have diverse applications in food preservation. This work shows a novel alternative to prepare a cryostructured composite coating made from a blend of xanthan, bovine collagen, and oregano essential oil. The composite coating was suitably applied onto the surface of preservative-free biscuits which were stored for 15 days at 25 ± 2°C and 52% ± 1% relative humidity. The evaluation focused mainly on the changes in the physicochemical, textural, and microbiological characteristics of the biscuits. It was found that the coated samples significantly (p < 0.05) decreased moisture absorption, water activity, and fungal growth. However, the composite coating minimally impacted the quality of biscuits in terms of color, texture profile, and surface microstructure. Overall, the cryostructured composite coating constitutes an advance in technological strategies aimed at the preservation of baked products. This will allow, in the future, the development of novel coatings on bakery products to generate new trends in the conservation of their properties and extension of shelf life. This could be achieved through the implementation of new technologies in the food industry, with the aim of making them more environmentally friendly and contributing to the generation of less plastic waste. PRACTICAL APPLICATION: The study and application of cryogels, as innovative systems in the food industry, allow to expand and diversify the materials that can function as coatings to maintain some quality characteristics, in this case in bakery products, so it is important to analyze their effects and consider them to improve conservation processes.

RESUMO

Introduction. The intake of energy-dense unhealthy food at school could influence the overall energy intake of children. Objective: To characterize the patterns of buying a snack at school and to analyze the association of these patterns with the source of the school snack (brought from home or bought at school) and screen time. Materials and methods: A cross-sectional study was conducted from October 2018 until May 2019 among school children (9 to 12-year-olds) from Cuenca-Ecuador. Intake of energy-dense unhealthy food groups, the source of the school snack, and screen time were assessed using questionnaires. Multiple correspondence analysis was used to identify intake patterns of unhealthy food groups, and logistic regression to assess the association between intake of energy-dense unhealthy food groups (FG) with the school snack source. Results: Among 1,028 children recruited 63%, 42%, 30% and 22% of the children reported consuming sweets/confiture, savory snacks, fast food, and pastry products, respectively, at least two days per week. Around 39% of the children were classified as "Frequent consumers of energy-dense unhealthy FG". Buying the snack at school was associated with a more frequent intake of sweets/confiture (OR=1.56, CI 95% =1.05-2.32) and fast food (OR=2.01, CI 95% =1.15-3.50) during the week, as well as with being classified in the "frequent consumer of energy-dense unhealthy FG" (OR=1.99, 95% CI=1.40-2.82). Conclusions: Ecuadorian children still consume prohibited unhealthy foods at school. These results reinforce the importance of evaluating, monitoring, and adapting strategies to promote a balanced diet(AU)

Introducción. La ingesta de alimentos poco saludables con alto contenido energético en la escuela podría influir en la ingesta energética total de los niños. Objetivo: Caracterizar los patrones de compra de snacks en el colegio y analizar la asociación de estos patrones con la procedencia del snack escolar (de la casa o comprada en el colegio) y el tiempo de pantalla. Materiales y métodos: Se realizó un estudio transversal (octubre 2018-mayo 2019) en escolares (9-12 años) Cuenca- Ecuador. La ingesta de grupos de alimentos (FG) no saludables altos en energía, la fuente del snack escolar y el tiempo de pantalla se evaluaron mediante cuestionarios. Se utilizó análisis de correspondencias múltiples para identificar patrones de ingesta de FG poco saludables y la regresión logística para evaluar asociación entre la ingesta FG no saludables con la fuente del snack escolar. Resultados: En 1.028 niños 63%, 42%, 30% y 22% declararon consumir dulces/golosinas, aperitivos salados, comida rápida y productos de pastelería, respectivamente, al menos dos/días/ semana. Un 39% fueron clasificados como "Consumidores frecuentes de FG poco saludables de alta densidad energética". La compra de los snacks en el colegio se asoció con una ingesta más frecuente de dulces/golosinas (OR=1,56; IC95%=1,05-2,32) y comida rápida (OR=2,01; IC95%=1,15-3,50) durante la semana y con la clasificación en el grupo" consumidores frecuentes de FG poco saludables de alta densidad energética" (OR=1,99; IC95%=1,40- 2,82). Conclusiones: Los niños ecuatorianos aún consumen alimentos no saludables prohibidos en la escuela. Estos resultados refuerzan la importancia de evaluar, monitorear y adaptar estrategias para promover una dieta balanceada(AU)

RESUMO

In this work, a novel analytical methodology for the extraction and determination of polycyclic aromatic hydrocarbon derivatives, nitrated (NPAH) and oxygenated (OPAH), in bee honey samples was developed. The extraction approach resulted in being straightforward, sustainable, and low-cost. It was based on a salting-out assisted liquid-liquid extraction followed by liquid chromatography-tandem mass spectrometry determination (SALLE-UHPLC-(+)APCI-MS/MS). The following figures of merit were obtained, linearity between 0.8 and 500 ng g-1 for NPAH and between 0.1 and 750 ng g-1 for OPAH compounds, coefficients of determination (r2) from 0.97 to 0.99. Limits of detection (LOD) were from 0.26 to 7.42 ng g-1 for NPAH compounds and from 0.04 to 9.77 ng g-1 for OPAH compounds. Recoveries ranged from 90.6% to 100.1%, and relative standard deviations (RSD) were lower than 8.9%. The green assessment of the method was calculated. Thus, the Green Certificate allowed a classification of 87 points. This methodology was reliable and suitable for application in honey samples. The results demonstrated that the levels of nitro- and oxy-PAHs were higher than those reported for unsubstituted PAHs. In this sense, the production chain sometimes transforms foods as direct carriers of contaminants to consumers, representing a concern and demonstrating the need for routine control.

RESUMO

Identificar irregularidades em restaurantes pode auxiliar a minimizar riscos de contaminação. O objetivo desse estudo foi analisar as irregularidades registradas em inspeções sanitárias de restaurantes e similares em Curitiba, Brasil, entre 2005 a 2017. A descrição das irregularidades foi organizada seguindo as categorias e os itens da legislação de Boas Práticas (BP) para serviços de alimentação do Brasil e as cinco chaves para uma alimentação mais segura, definidas pela Organização Mundial da Saúde. Do total de 4.098 registros, houve a descrição de 8.327 irregularidades. Em relação às BP, houve a prevalência da descrição de irregularidades nos anos de 2005, 2006 e 2013, e das categorias: edificações, instalações, equipamentos, móveis e utensílios (42,80%); preparação do alimento (11,54%); documentação e registro (9,92%) e matéria-prima, ingredientes e embalagens (9,06%). Em relação às cinco chaves para uma alimentação mais segura, apenas 3.209 (38,53%) descrições correspondiam a esse tema, com destaque a: manter a limpeza (40,70%) e usar água e matérias-primas seguras (34,71%). Houve uma tendência decrescente na descrição das irregularidades no período estudado, porém ainda é um desafio implementar as BP em restaurantes e similares no Brasil, o que pode favorecer a ocorrência de doenças e aumentar o risco à saúde da população.

Identifying irregularities in restaurants can help minimize contamination risks. The objective of this study was to analyze the irregularities recorded in sanitary inspections of restaurants and similar establishments in Curitiba, Brazil, between 2005 and 2017. The description of the irregularities was categorized following the items and criteria outlined in the Good Practices (GP) legislation for food services of Brazil and the Five Keys to Safer Food, defined by the World Health Organization. Out of the total of 4,098 records, 8,327 irregularities were documented. Concerning GP, there was a prevalence of irregularities described in the years 2005, 2006 and 2013, mainly in the following categories: buildings, installations, equipment, furniture and utensils (42.80%); food preparation (11.54%); documentation and registration (9.92%) and raw materials, ingredients and packaging (9.06%). Regarding the Five Keys to Safer Food, only 3,209 (38.53%) corresponded to this theme, with particular emphasis on maintaining cleanliness (40.70%) and using safe water and raw materials (34.71 %). The study observed a declining trend in the description of irregularities over the study period. However, the successful implementation of GP in restaurants and similar establishments in Brazil remains a challenge, potentially favoring the occurrence of foodborne diseases and increasing the risk to public health.

RESUMO

Maternal food habits and gut microbiota composition have potential effects on fetal neurodevelopment, impacting Autism Spectrum Disorder (ASD). Our research aims to outline the relationship that ingestion of polyunsaturated fatty acids (PUFAs) and the composition of maternal gut microbiota have with the possible development of ASD in offspring. We suggest that genetic factors could be related to the different conversions between unsaturated fatty acids according to sex and, mainly, the impact of the pregnancy diet on the higher or lower risk of neurological impairments. The proportion of the phyla Firmicutes/Bacteroidetes is high with an increased consumption of linoleic acid (LA, n-6 PUFA), which is associated with maternal intestinal dysbiosis and consequently starts the inflammatory process, harming myelinization. In contrast, the consumption of α-linolenic acid (ALA, n-3 PUFA) tends to re-establish the balance of the maternal microbiota with anti-inflammatory action. Moreover, human observational studies showed a strong correlation between the consumption of n-3 PUFA, mainly above 340 g of fish per week, with beneficial effects on infant neurodevelopment. Therefore, we suggest that the proper intake of foods rich in n-3 PUFAs and their supplementation during pregnancy until lactation has an impact on reducing the development of ASD. Controlled studies with n-3 PUFA supplementation are still necessary to verify the ideal dose and the best form of administration.

RESUMO

The food consumption of adolescents has changed nowadays, with an increase in ultra-processed food that in general shows higher calories and lower nutrients. Because of this, the objective of this study was to investigate the impacts of a 12-week multi-professional family versus isolated intervention on the food level processing of overweight adolescents. A randomized clinical trial study was carried out in which adolescents (n = 43; mean aged 13.73 years) who were divided into FG-family group (n = 21; the adolescents performed the activities with their parents) and IG-isolated group (n = 22; the adolescents performed the activities alone). The parameters measured before and after 12 weeks of multi-professional intervention (physical exercise, nutrition and psychoeducation) were: body mass, height and body mass index-BMI. The level of food processing was analyzed using a three-day food recall (24hR), classified according to the Food Guide for the Brazilian Population (fresh, minimally, processed and ultra-processed foods). The main results show that there was only a significant reduction in the consumption of processed foods (FG: 7.93%; IG: 49.73%) and ultra-processed foods (FG: 35.06%; IG: 67.16%) in grams (FG: 22.29%; IG: 65.23%) and calories (p < 0.05; for all comparisons). The consumption of fresh foods in grams (FG:61.97%; IG: 147.13%) and calories (FG: 147.13%; IG: 118.03%) and minimally processed foods (FG: 27.45%; IG: 14.64%) in grams increased significantly (p < 0.05; for all comparisons). However, no significant differences were observed between all variables analyzed for the groups, nor any interaction (p > 0.05). In conclusion, both groups who participated in the activities showed positive changes with increased consumption of fresh foods and reduced consumption of processed foods, without difference between them.

RESUMO

La adulteración y el fraude de productos alimenticios son tan antiguos como los sistemas de procesamiento y producción de alimentos, sin embargo, en la actualidad son cada vez más frecuentes. Con la globalización y los sistemas de producción y distribución de alimentos cada día más complejos, la adulteración puede ocurrir en distintos puntos de la cadena alimentaria y tener un impacto de gran alcance, e incluso, consecuencias adversas para la salud de las personas. Los enfoques regulatorios de la comunidad internacional para enfrentar y resolver el fraude alimentario están dispersos y en constantes ajustes. Se necesita un enfoque colectivo y coordinado para identificar a todos los interesados en la cadena de suministro de alimentos, calificarlos y certificarlos, excluir a aquellos que no cumplan con los estándares adecuados y rastrear los alimentos en tiempo real. Este artículo de actualización revisará conceptos claves asociados a la integridad alimentaria, historia del fraude alimentario y episodios de fraude alimentario de connotación pública en el mundo y en Chile, herramientas analíticas y alimentos más vulnerables al fraude, reglamentos y nuevas acciones en el mundo y en Chile para enfrentar la inocuidad y el riesgo de fraude alimentario.

Food adulteration and food fraud is as old as food production and processing however, it is increasingly prevalent today. With globalization and increasingly complex food production and distribution systems, adulteration can occur at different points in the food chain and may have far-reaching impacts and even adverse consequences for human health. The international community's regulatory approaches to confronting and resolving food fraud are scattered and in constant adjustment. A collective and coordinated approach is needed to identify all stakeholders in the food supply chain, certify and qualify them, exclude those who do not meet applicable standards, and trace food in real time. This update provides definitions and background on key concepts associated with food integrity, episodes of food fraud in Chile and the world, main foods vulnerable to food fraud, common fraud practices and analytical techniques, regulations and new actions in Chile and the world to face food safety and the risk of food fraud.

RESUMO

Staphylococcus aureus is a natural commensal microflora of humans which causes opportunistic infections due to its large arsenal of exotoxins, invasion, immune evasion, and antibiotic resistance mechanisms. The primary goal of this study is to develop a multiplex PCR (mPCR) assay for simultaneous detection of Staphylococcus aureus (nuc) and its virulence genes coding for prominent exotoxins namely alpha hemolysin (hla), enterotoxins A (sea), enterotoxin B (seb), toxic shock syndrome toxin (tsst-1), and the gene coding for methicillin resistance (mecA). A competitive internal amplification control (IAC) was included in the assay to exclude the false negative outcomes. Highly specific primer pairs were designed for the target genes using in silico resources. At the outset, monoplex PCRs were standardized using reference S. aureus strains. Primer specificity to the target genes was authenticated through restriction digestion analysis of amplified PCR products. Multiplex PCR was optimized in increments of one gene starting with nuc and IAC amplified simultaneously using one pair of primers (nuc) in a competitive manner. The mPCR assay was found to be highly sensitive with a detection limit of ~10 CFUs per reaction for pure cultures. Multiplex PCR assay was further evaluated on the retail and processed food samples to test the prevalence of S. aureus and study their exotoxin profiles. Of the 57 samples examined, 13 samples (22.80%) were found to be contaminated with S. aureus whose DNA was extracted after a 6-h enrichment period. Among these, a high percentage of hemolytic and enterotoxin A positive strains were encountered. The mPCR assay developed in this study would be a useful tool for rapid and reliable monitoring of S. aureus for food quality testing and from clinical infections.

RESUMO

Upwelling oceanographic phenomenon is associated with increased food availability, low seawater temperature and pH. These conditions could significantly affect food quality and, in consequence, the growth of marine species. One of the most important organismal traits is somatic growth, which is highly related to skeletal muscle. In fish, skeletal muscle growth is highly influenced by environmental factors (i.e. temperature and nutrient availability) that showed differences between upwelling and downwelling zones. Nevertheless, there are no available field studies regarding the impact of those conditions on fish muscle physiology. This work aimed to evaluate the muscle fibers size, protein content, gene expression of growth and atrophy-related genes in fish sampled from upwelling and downwelling zones. Seawater and fish food items (seaweeds) samples were collected from upwelling and downwelling zones to determine the habitat's physical-chemical variations and the abundance of biomolecules in seaweed tissue. In addition, white skeletal muscle samples were collected from an intertidal fish to analyze muscular histology, the growth pathways of protein kinase B and the extracellular signal-regulated kinase; and the gene expression of growth- (insulin-like growth factor 1 and myosin heavy-chain) and atrophy-related genes (F-box only protein 32 and muscle RING-finger protein-1). Upwelling zones revealed higher nutrients in seawater and higher protein content in seaweed than samples from downwelling zones. Moreover, fish from upwelling zones presented a greater size of muscle fibers and protein content compared to downwelling fish, associated with lower protein ubiquitination and gene expression of F-box only protein 32. Our data indicate an attenuated use of proteins as energy source in upwelling conditions favoring protein synthesis and muscle growth. This report shed lights of how oceanographic conditions may modulate food quality and fish muscle physiology in an integrated way, with high implications for marine conservation and sustainable fisheries management.

RESUMO

Abstract Foodborne diseases are common illnesses caused by the consumption of food contaminated with microorganisms, such as viruses, fungi, bacteria, and protozoa. Every year, 600 million people become ill and 420,000 people die as a result of consuming contaminated food. Therefore, food safety is an important issue. In this study, samples of homemade spiced mayonnaise and self-serve acai sold in the city of Araguaína, Tocantins, Brazil were analyzed for microbiological contaminants. Acai was collected from 10 stores, one sample from each store, and tested for mold, yeast, and coliforms, as well as coliform identification and total and thermotolerant coliform counts. Mayonnaise was collected from 20 snack bars, one sample from each. These samples were inoculated on MacConkey and Salmonella Shigella agar plates, and the plates were analyzed for growth. Salmonella spp. were detected in some Mayonnaise samples, and coliforms were detected in all acai samples; 60% of samples had thermotolerant coliforms, and only 40% were within the limits established by ANVISA. The collected samples of mayonnaise and acai were contaminated with molds and yeasts above the established limit of 103 CFU/g. Thus, the analyzed mayonnaise and acai samples were contaminated and unfit for consumption, demonstrating the importance of hygienic-sanitary measures in food handling.

Resumo As doenças transmitidas por alimentos são doenças comuns causadas pelo consumo de alimentos contaminados com microrganismos, como vírus, fungos, bactérias e protozoários. Todos os anos, 600 milhões de pessoas ficam doentes e 420.000 pessoas morrem como resultado do consumo de alimentos contaminados. Portanto, a segurança alimentar é uma questão importante. Neste estudo, amostras de maionese temperada caseira e açaí self-service vendidas na cidade de Araguaína, Tocantins, Brasil foram analisadas quanto a contaminantes microbiológicos. O açaí foi coletado em 10 lojas, uma amostra de cada loja, e testado para mofo, levedura e coliformes, bem como identificação de coliformes e contagem de coliformes totais e termotolerantes. A maionese foi coletada de 20 lanchonetes, sendo uma amostra de cada. Essas amostras foram inoculadas em placas de ágar MacConkey e Salmonella Shigella, e as placas foram analisadas quanto ao crescimento. Salmonela spp. foram detectados em algumas amostras de maionese e coliformes foram detectados em todas as amostras de açaí; 60% das amostras apresentaram coliformes termotolerantes, e apenas 40% estavam dentro dos limites estabelecidos pela ANVISA. As amostras coletadas de maionese e açaí estavam contaminadas com bolores e leveduras acima do limite estabelecido de 103 UFC/g. Assim, as amostras de maionese e açaí analisadas estavam contaminadas e impróprias para o consumo, demonstrando a importância das medidas higiênico-sanitárias na manipulação de alimentos.

RESUMO

Abstract Objectives: characterize the availability and assess the nutritional quality of children's menus ofered in regular and fast food restaurants in Brazilian malls. Methods: this is an observational and cross-sectional study. Data were collected on the websites of each restaurant and in food sales applications, with a questionnaire consisting of two sections: characterization of the restaurant and characterization of the children's menu. Data collection took place in ten capitals in the fve regions of Brazil. Results: 116 children's menus were evaluated. The study identifed a higher number of regular (n=70, 60%) than fast-food (n=46,40%) restaurants. The cooking methods most used in the main dishes were grilled (n=236, 64%) and boiled (n=74, 20%), and in the side dishes were boiled (n=204, 53%) and fried (n=109, 28%). Only 40% (n=46) of the menus contained vegetables. Less than 10% (n=seven) ofered fruit as dessert, 31% (n = 36) had drinks included in the children's menu and 22% (n=25) ofered gifts associated with the menu. Only 32 (28%) restaurants had the combination of beans and rice. Conclusion: most of the options ofered to children were of low nutritional quality, with low ofer of vegetables, fruits and the traditional beans and rice. The beverages included in the menus, most of them sugary, can contribute to a high-energy intake. There is a need to provide healthy options and encourage these choices.

RESUMO

RESUMEN Durante las últimas décadas la migración aumentó considerablemente en Chile generando preocupación por la salud de los migrantes. Respecto de la alimentación en escolares, la evidencia no es concluyente, por un lado, las preferencias alimentarias orientadas al territorio de acogida han sido asociadas a una menor calidad de la alimentación sumado a indicadores de malnutrición y por otro, escolares migrantes que presentaron menor riesgo de malnutrición por exceso. El objetivo de esta investigación fue comparar la calidad global de la alimentación y las preferencias alimentarias de escolares chilenos y migrantes residentes en Chile. Se realizó un estudio transversal de tipo descriptivo, el cual incluyó una muestra de 534 escolares migrantes y no migrantes, de ambos sexos, los cuales fueron seleccionados por conveniencia, completando un cuestionario sobre calidad de la alimentación y preferencias alimentarias. Se analizaron distribuciones de frecuencias mediante la prueba de Chi2 por grupos. Escolares migrantes reportaron una mejor calidad global de la alimentación que escolares chilenos (p= 0,002), con mejores indicadores. Respecto a la calidad global de la alimentación por tiempo de residencia, se observaron diferencias estadísticamente significativas (p= 0,025) en favor de aquellos migrantes con más de 5 años de residencia. La calidad global de la alimentación aumentó en migrantes cuando las preferencias alimentarias estuvieron orientadas al territorio de origen. En escolares chilenos la calidad global de la alimentación aumentó, cuando prefirieron alimentos que no son tradicionales de Chile. En conclusión, escolares migrantes reportaron una mayor calidad global de la alimentación que chilenos, y esta aumenta cuando el tiempo de residencia es de 5 o más años. Es necesario seguir indagando sobre la calidad global de la alimentación y las preferencias alimentarias en escolares migrantes.

ABSTRACT During the last decades, migration increased considerably in Chile, generating concern for the health of migrants. On the one hand, food preferences oriented to the host territory have been associated with lower food quality and indicators of malnutrition; on the other hand, migrant schoolchildren present a lower risk of excess malnutrition. The objective of this research was to compare the overall food quality and food preferences of Chilean and migrant schoolchildren residing in Chile. A descriptive cross-sectional study was carried out, which included a sample of 534 migrant and non-migrant schoolchildren, of both sexes, who were selected by convenience, completing a questionnaire on food quality and food preferences. Frequency distributions were analyzed using the chi-square test by groups. Migrant schoolchildren reported better overall food quality compared to Chilean schoolchildren (p= 0.002), with better indicators in the dimensions of healthy, unhealthy food, and meal times. We observed statistically significant differences in overall food quality by time of residence (p= 0.025) in favor of those migrants with more than 5 years of residence. It is noteworthy that the healthy category reached its highest proportion (41.4%) among those with five or more years of residence in Chile. The overall quality of food increased in migrants when food preferences were oriented to the territory of origin. In Chilean schoolchildren, overall food quality increased when they preferred foods not characteristic of Chile. In conclusion, migrant schoolchildren reported a higher overall food quality compared to Chilean schoolchildren, and this increased when the time of residence was 5 or more years. Further research is needed on the overall food quality and food preferences of migrant schoolchildren.

RESUMO

The effect of water activity (aW; 0.87, 0.90, 0.92, 0.94, 0.96, 0.98 and 0.99), temperature (15, 25, and 30 °C), incubation time (5, 10, 14, and 21 days), and their interactions on mycelial growth and aflatoxin production in a chickpea-based medium by three Aspergillus flavus strains isolated from chickpea grains in Argentina was evaluated. Maximum growth rates were obtained at the highest aW (0.99) and 30 °C, with growth decreasing as the aW of the medium was reduced. Maximum levels of aflatoxins were produced at 0.99 aW and 25 °C after 5 days of incubation for two strains, and at 25 °C and 0.96 aW after 21 days of incubation for the third strain. The aflatoxin concentrations varied considerably depending on the aW and temperature interactions assayed. Two-dimensional profiles of aW by temperature interactions were developed from these data to identify areas where conditions indicate a significant risk from aflatoxin accumulation on chickpea. This study provides useful baseline data on conditions representing a high and a low risk for contamination of chickpea by aflatoxins which is of greater concern because this pulse is destined mainly for human consumption.

RESUMO

BACKGROUND AND OBJECTIVES: The confinement by COVID-19 has affected the food chain and environments, which added to factors such as anxiety, frustration, fear and stress have modified the quality of the diet in the population around the world. The purpose of this study was to explore diet quality during the COVID-19 pandemic in 11 Latin American countries. METHODOLOGY: Multicentric, cross-sectional study. An online survey was applied to residents of 11 Latin-American countries, during April and May 2020, when confinement was mandatory. Diet quality was evaluated using a validated questionnaire. RESULT: 10,573 people participated in the study. The quality of the food by country shows that Colombia presented the best quality, while Chile and Paraguay presented the lowest. When comparing the overall results of diet quality by gender, schooling and age, women, people with more schooling and people under 30 years of age, presented better diet quality. The regression model showed that the variables associated with diet quality were: age (df = 3, F = 4. 57, p < 0.001), sex (df = 1, F = 131.01, p < 0.001), level of education (df = 1, F = 38.29, p < 0.001), perception of weight change (df = 2, F = 135.31, p < 0.001), basis services (df = 1, F = 8.63, p = 0.003), and quarantine (df = 1, F = 12.14, p = 0.001). CONCLUSION: It is necessary for governments to intervene to reverse these indicators, considering that inadequate feeding favors the appearance of no communicable diseases, which favor a higher risk of infection and worse prognosis with COVID-19.

RESUMO

Abstract: Objective: To identify the behavioral and normative believes factors that might have major influence on the decision to buy packaged foods in urban Mexican families. Materials and methods: We performed a cross-sectional study in four urban cities of Mexico. Participants responded a self-administered questionnaire (n=3 340) outside of randomly selected supermarkets. A factor analysis was performed to identify what were the main behavioral and normative believes explaining consumers' decision when buying packaged foods. Results: Three factors explained the behavioral beliefs: the quality assessment of packaged foods explained 61% of the variance, products that maintain weight explained 25%, and the emotional experience with foods explained 13%. Three factors explained the normative beliefs: expectations of children and partner explained 46% of the variance, expectations from the participants' closest friends 23%, and expectation from other family members explained 14%. Conclusion: Behavioral and normative beliefs related to assessing the quality of foods and meeting family expectations respectively are the main beliefs factors affecting consumers' packaged food purchase decisions in urban consumers.

Resumen: Objetivo: Identificar las creencias de comportamiento y normativas que tienen mayor influencia en las decisiones de familias urbanas en México para comprar alimentos empaquetados. Material y métodos: Se realizó un estudio transversal en cuatro ciudades urbanas de México. Los participantes respondieron un cuestionario auto-administrado (n=3 340) a la salida de los supermercados que fueron seleccionados aleatoriamente. Se realizó un análisis factorial para identificar los principales factores de las creencias de comportamiento y normativas que explican la decisión de comprar alimentos empaquetados. Resultados: Tres factores explicaron las creencias conductuales: la evaluación de la calidad de los alimentos empaquetados explicó el 61% de la varianza, productos para control de peso explicaron el 25% y la experiencia emocional con los alimentos el 13%. Tres factores explicaron las creencias normativas: las expectativas de la pareja e hijos explicaron el 46% de la varianza, las expectativas de amigos cercanos el 23% y las expectativas de otros familiares explicaron el 14%. Conclusión: En las creencias conductuales, la evaluación de la calidad de los alimentos y en las creencias normativas, la expectativa de la pareja y los hijos tienen gran influencia en la decisión de compra de alimentos empaquetados en los consumidores de los supermercados urbanos en México.

RESUMO

Studies indicate that eating locations can influence food choices. However, the relationship with ultra-processed foods has been little explored. The objective was to assess the association between eating locations and ultra-processed foods consumption in the UK in 2014-2016. Data from 2,449 individuals aged 4 years or older from the NDNS were analysed cross-sectionally. Food consumption information was collected through 4-day food diaries. Recorded foods were classified into NOVA system. The eating locations were grouped into nine categories (home, institutional places, sit-down restaurants, on the go, coffee shops, leisure and sports clubs, fast food, friends and relatives' house, and other places). Linear regression models were carried out. The coefficients represent the increment in the contribution of ultra-processed foods to total energy intake for each percentage point increase in the contribution of each eating location to total energy intake. Among children, consumption at home was inversely associated with ultra-processed foods consumption (ß: -0.10; 95% CI -0.17, -0.03), while in leisure and sports places (0.47; 0.20, 0.73) directly associated. For adolescents, eating at home (-0.12; -0.19, -0.05) was inversely associated with the consumption of ultra-processed foods, as well as sit-down restaurants (-0.21; -0.38, -0.03). Fast food (0.29; 0.12, 0.47) were directly associated with the consumption of ultra-processed foods for adolescents. Finally, for adults, sit-down restaurants (-0.13; -0.22, -0.03) showed to be inversely associated with the consumption of ultra-processed foods while in fast food restaurants (0.77; 0.38, 1.17) it was directly associated. Our results showed that the eating locations have different impacts on diet quality.

RESUMO

The outbreak of the coronavirus disease (COVID-19) is global health and humanitarian emergency. To respond effectively to this pandemic, it is mandatory to reaffirm science in its different fields of study, including the food safety area. Presently, we review food safety in times of COVID-19, exploring whether the virus can be transmitted by food or water; recommendations from regulatory agencies; perceptions of food hygiene practices during the pandemic; and post-pandemic perspectives. The review was based on papers published in Web of Science, Scopus, Pubmed, and covered recommendations of public health protection and regulatory agencies around the world. The transmission of the severe acute respiratory syndrome (SARS-CoV-2) by food was not confirmed until the present time. In any case, the protocols already established for food safety were reinforced, emphasizing the proper hygiene of hands after shopping, handling food packages, or before manipulating or eating food, adequate social distance, the use of individual protection equipment, the health of employees, and the proper preparation of food. It is hoped, in the post-pandemic scenario, to reach a better understanding of the particularities that led to greater care with food hygiene. Moreover, it is expected that the food system will creatively adapt the way meals are served.
