RESUMEN
BACKGROUND: An increased production of cherry and gourmet tomato cultivars that are harvested at advanced colour stages and sold at a higher price has been observed in the last 10 years. In this context, producers need information on the sensory characteristics of new cultivars and their perception by potential consumers. The aim of the present work was to obtain a sensory characterisation of nine cherry tomato cultivars produced under Brazilian organic cultivation conditions from a chef and consumer perspective. Nine organic cherry tomato genotypes were evaluated by ten chefs using an open-ended question and by 110 consumers using a check-all-that-apply question. RESULTS: Both methodologies provided similar information on the sensory characteristics of the cherry tomato accessions. The superimposed representation of the samples in a multiple factor analysis was similar for consumers' and chefs' descriptions (RV coefficient 0.728), although they used different methodologies. According to both panels, cherry tomatoes were sorted into five groups of samples with similar sensory characteristics. CONCLUSION: Results from the present work may provide information to help organic producers in the selection of the most promising cultivars for cultivation, taking into account consumers' and chefs' perceptions, as well as in the design of communication and marketing strategies.

In this study the hepatic lipoprotein lipase (LPL), activity was evaluated in adult female mice acclimatized at 5-C and submitted to carbon tetrachloride (CCI) or ethionine, in order to determine the possible role of this enzuyme in the fatty liver. The results were compared with those obtained in mice kept at room temperature (27-C) that the same hepatoesteatosis inducing agent. In contrast to animals kept at room temperature, in cold aclimatized mice neither the enhancement of the LPL-liver activity by the action of CCI or ethionine occurred nor the development of fatty infiltration in the liver was observed. We conclude that the low temperature induced a protective effect against CCI or ethionine-induced fatty liver that was correlated with the no-increase of the hepatic LPL activity
