Abstract

In line with the new concept of functional food, there has been great incentive to the study of a series of bioactive substances found in food and their beneficial effects to health. Carotenoids are the bioactive phytochemicals most studied and our group has been contributing to advances in this area in different aspects: (a) development of analytical methods; (b) identification and quantification of carotenoids in Brazilian food, resulting in an extensive and reliable database; ( c) verification of the factors that influence the carotenoid composition of food; (d) investigation of stability; ( e) evaluation of the effects of processing and storage of food; (f) characterization of alternative sources of carotenoids. Our knowledge, experience and established infrastructure for carotenoid research are being extended to the study of other substances currently recognized for their importance in health, and for which there is a dearth of information in the country, such as polyphenols, including the phenolics in coffee, and folates. As with carotenoids, the present project has the objective of elaborating a reliable database of the polyphenol and folate contents of Brazilian food. It is also aimed at verifying the factors that influence the composition in order to recommend means of increasing these compounds in Brazilian food. Aside from furnishing information about stability, processing and storage procedures for minimally processed vegetables in modified atmosphere packaging, dehydrated products pre-treated osmotically and microencapsulated products, with optimum retention of the bioactive compounds will also be established. Additionally, the mode of action of the coffee phenolics will also be studied. (AU)
