By-products of tropical fruits dehydrated by convective
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2018, Vol 13, Issue 4
Abstract
Brazil, in recent years, has expanded its agroindustrial production, increasing, consequently, the amount of waste produced. An alternative its utilization is the transformation of these by-products by drying, since dehydrated products have been highlighted by the practical form of commercialization. One way to use these residues after their dehydration is the incorporation of the same ones in the form of powders, in foodstuffs. In view of the above, the objective was to study the dehydrated manure (RDM), guava (RDG) and acerola (RDA) residues obtained by means of convective drying (55ºC/ 48h). The physico-chemical characteristics (aw, moisture, total solids, ash, total acidity, acidity expressed as citric acid, pH, soluble solids, centesimal composition and calorific value), colorimetric, functional properties and hygienic-sanitary quality of dehydrated residues . RDM stands out in relation to the soluble solids content (51,65 °Brix). RDG presented higher total solids (93,91%), pH (4,23%) and lipids (7,15%) in relation to the others. RDA showed higher total acidity (10,79%), acidity in citric acid (6,91%), ash (3,28%) and protein (15,40%). RDM and RDG presented higher amount of carbohydrates present, however, RDG contains higher caloric value (402,91 Kcal). Regarding the colorimetric analysis, RDG showed better staining. In relation the functional properties, RDA was highlighted in terms of phenolic compounds, antioxidant activity and vitamin C, while RDG was highlighted in terms of carotenoid content. Regarding microbiological parameters, all dehydrated residues met the requirements of the legislation. Residues of dehydrated tropical fruits can be applied in food products, due to their functional and nutritional properties.
