RESUMEN
This review explores the historical, botanical, sensory, and quality aspects of Coffea canephora, with a focus on Brazil's rise as a producer of specialty canephora coffees in the Amazon region, Espírito Santo, and Bahia. Brazil has gained global recognition through the first geographical indications for canephora: Matas de Rondônia for robusta amazônico coffee and Espírito Santo for conilon coffee. Despite this, comprehensive insights into how variety, terroir, environmental conditions, and cultivation practices influence the chemical and sensory attributes of Brazilian canephora remain underdeveloped compared to well-studied arabica coffee. Producers and researchers are working to elevate canephora coffees to higher market levels, despite technological, production, and perception challenges stemming from its historical reputation for poor quality. Ensuring the sustainability of Amazonian canephora coffee without deforestation is particularly challenging due to the need to verify practices across numerous small-scale farms. There is also a critical need for standardized production and tasting protocols for Brazilian canephora, leveraging local expertise and professional cuppers to ensure consistent quality and reliable sustainability claims. Significant opportunities exist in valuing the production chain of geographically unique canephora coffees, which could increase specialty exports, enhance economic prospects for local farmers, and support Amazon preservation. Recognizing and marketing these coffees as premium products with unique flavor profiles can boost their global appeal. Another challenge lies in establishing new specialty standards for soluble coffee from specialty canephora to meet consumer demands for convenience without compromising taste or ethical standards. In such a scenario, several analytical methods have been suggested to identify high-quality variants, combating their stigmatization. The potential of spectroscopy techniques and chemometrics-based data science is highlighted in confirming coffee quality, authenticity, traceability, and geographical origin, enhancing model interpretation and predictive accuracy through synergistic and complementary information. Non-targeted spectroscopic analyses, providing comprehensive spectral fingerprints, are contrasted with targeted analyses. Overall, this review offers valuable insights for the coffee scientific community, exporters, importers, roasters, and consumers in recognizing the potential of Brazilian canephora coffees.

Consumers are concerned with the amount of sucrose added to foods and its effects on human health. One way to reduce this concern is through the consumption of sucrose substitutes, such as isomaltulose. Isomaltulose is an alternative sugar that should be regarded by the food industry as much healthier than sucrose, due to its beneficial properties; these include, low glycemic index and slow hydrolysis, prebiotic potential, and low cariogenic potential. In this work, a bibliometric analysis associated with a review of literature was conducted as a rigorous method for exploring and analyzing large volumes of scientific data, to understand the global scenario and identify the trends regarding isomaltulose. Important facts from its history and origin were discussed, as well the main research and countries that have contributed to its growing interest in the food industry. Over the years, from the discovery of new beneficial properties, more studies have been conducted, demonstrating that the interest in isomaltulose has been increasing. Finally, we concluded that isomaltulose is a promising sucrose substitute that could change the scenario of the sugar-rich foods market; and its use for the development of new products is highly encouraged.

Objetivou-se com a presente pesquisa elaborar e caracterizar a composição físico-química de refresco de amora-preta adoçado com mel. Para a elaboração dos refrescos foram utilizados polpa de amora-preta extraída de frutos in natura e mel de abelha Apis Mellifera L., sendo processados em liquidificador industrial e acondicionados em garrafas plásticas de polietileno sob refrigeração. Os refrescos, a polpa e o mel utilizados foram submetidos às análises físico-químicas de acidez total titulável, sólidos solúveis totais, pH, Ratio, atividade de água, cinzas e umidade. Constatou-se que a polpa e mel utilizados na elaboração das bebidas encontravam-se conforme a legislação e foi possível elaborar refrescos de amora-preta com adição de mel, agregando valor as matérias-primas.
