RESUMO O trabalho teve como objetivo desenvolver e caracterizar embalagens ativas fl exíveis formuladas pela incorporação de polpas de frutas tropicais a uma matriz polimérica

There are several fruits native to cultivated in Brazil that have not been studied for their antioxidant potential and functional characteristics. This study characterized the physico-chemical composition, mineral and levels of compounds of the pulp and peel of ten fruits. The evaluated fruits were atemoya, ambarella, breadfruit, soursop, jackfruit, lychee, mangaba, sapodilla, hog plum, and sugar apple. Higher protein content was observed (from 1.24 to 3.43g/100 g) in the peel and the pulp in fruits of the Annonaceae family (atemoya, cherimoya and sugar apple), and the sapodilla showed higher lipid content (2.37 and 3.37g/100g, for pulp and peel respectively). In general, concentration of minerals was higher in the peel than in the pulp. The fruits of the Annonacea family had the highest total phenolic values mainly in the peel. The highest anthocyanin and flavonoids content was found in the peel of lychee, and in the mangaba peel, respectively. Most fruits had higher concentration of the investigated analytes (physicalchemicals, minerals and phytochemicals) in the peels (considered waste from agricultural industries) against their respective pulps.
