Технологичность альтернативных сырьевых источников для получения пищевого хитозана

Abstract

A brief review of the market of producers of chitosan and industry potential consumers of the biopolymer. Chitosan is a promising component for modification of the prescription food due to functional-technological and bio correction properties. Traditional resource base of chitosan nibs from the shells of crab has a high cost and limited resources. The evaluation of process efficiency in the use of alternative raw materials shells of freshwater crayfish, shrimp, industrial waste recycling oyster mushroom for dietary chitosan. Technological parameters in assessing the effectiveness of various types of raw materials were the number of stages in the production of chitosan, the total duration of the process of chitosan and the output of the finished product. Chitosan from various sources received by traditional technology, comprising the sequential steps of deproteinizovana and demineralization of chitin-containing raw material obtained by deacetylation of chitin. The results show that for dietary chitosan to use the most technologically advanced crab by-products raw shrimp in comparison with other sources available in the regions remote from the pool of the king crab catch.
