Avaliação das propriedades físico-químicas do colágeno extraído do coproduto de tilápia

Abstract

The tilápia represents a great importance in the sector of the aquaculture, and is one of the species more produced commercially. The collagen is a found fibrous protein in conjunctive fabrics of the body, that has the function to contribute with the resistance and elasticity of fabrics, in its bigger part is gotten through generated residues, in the bovines, swines, fish, among others. The attainment of the extracted collagen of co-product of the tilápia of the Nile (Oreochromis niloticus) indicates an alternative in the use of the generation of residues of the production. The present study it was carried through by neutral daily pay-treatment with water, having varied time and temperature and had been evaluated characteristic as centesimal composition (humidity, leached ashes and proteins) and distinguishing exploratory calorimetry (DSC). The gotten collagen presents basses 1,45 leached ashes texts 2.18%. In relation to the humidity text, the same it presents texts of 9,56 11.67% and one high protein text of 83,46 87.71%. In this way, it was possible to conclude that the extration of the collagen of co-product of tilápia is a viable alternative for attainment of this product.
