Avaliação nutricional de frutas nativas da ilha de kanyaka

Abstract

The present work entitled ̋Nutritional Assessment of KaNyaka Island Native Fruits ̋ was developed within the scope of the degree work in Chemistry. It was based on the analysis of centesimal composition of several species of native fruits using methods of physical-analysis chemistry. The samples were collected in the vicinity of the Ilha Maritime Biology Station from KaNyaka (EBMK) After the collection and preparation of the samples, the following physico-chemical parameters were determined chemicals: glucose-reducing sugars, non-sucrose-reducing sugars, titratable acidity in organic acids, acidity titratable by volume with indicator, moisture, ash, proteins, fibers, phosphorus and minerals. Ignorance of the nutritional value of fruits leads to poor utilization, which causes the waste of high amounts of fruit. Nutritional assessment of fruits native to the island of KaNyaka is the object of study, in order to encourage their utilization and offer a low cost complementary diet alternative. The pulps of eight (8) samples of native fruits that normally ripen were analyzed from November to December, namely: Sclerocarya birrea, Syzygium cumini, Landolphia petersiana, Garcinia livingstonei, Landolphia kirkii, Syzygium cordatum, Mimusops caffra and Strychnos spinosa. The analyzes showed that the pulps present, in general, high levels of nutrients. In this way, it can be considered that the analyzed fruits can be useful as an alternative source of food "in natura" or ingredient for obtaining products processed. The results obtained indicate that the analyzed fruits have high nutritional value, being of recommend their processing, protection, conservation and propagation of species.
