Proximate composition and quantification of fatty acids in breaded chicken steak

The aim of this work was to analyze the fatty acid and proximate composition of five brands of breaded chicken steak (A, B, C, D, and E) by accurate chromatographic quantification and to compare the experimental results with food label nutrition facts. The protein values of all brands were in agreement with the Brazilian regulation values, except for that of sample E, which presented the highest lipid content. Thirteen fatty acids were identified in the studied brands and the major ones were oleic acid, linoleic acid, and palmitic acid. The polyunsaturated fatty acid/saturated fatty acid ratios were within the values considered appropriate for human health; however, the high n-6/n-3 ratios found can result in an unbalanced intake of these fat acids. Only samples D and E can be considered trans free according to the regulations. The comparison of the analyses' results and the food label nutrition facts showed little variation in protein values. Nevertheless, most brands underestimated their lipid and energy levels. Brand B and C labels declared "free of trans", but the obteined results showed levels excedding those especified by regulation to be considered trans free values.

Avaliação crítica da legislação brasileira de sucos de fruta, com ênfase no suco de fruta pronto para beber

The aim of this work was to critically assess the Brazilian regulations on fruit juices, with emphasis on ready-to-drink fruit juice. According to the Brazilian regulations, bottled fruit juices must follow specific regulations. They should be in accordance with the definition and designation that identify them, with the quality parameters established, and especially, follow the Brazilian food labeling regulations. The Brazilian regulations on bottled fruit juices have some gaps that promote their misunderstanding and marketing of substandard juices. Frequent changes, divergent labeling regulations and inappropriate use of expressions on the label can also lead to misinterpretation. Food regulations need to be clear and updated frequently if they are to be known and followed. Additionally, their wide dissemination should contribute to informed choices when buying.
