INTRODUCTION AND STUDY OF CHITIN AND CHITOSAN FROM ANIMAL BEES

Abstract

This article presents the results of producing chitin and chitosan biopolymers from a perspective new source – dried Apis mellifera bee. We used the dried and crushed dee collected during spring update of bee family and containing a significant amount of chitin. For extraction of chitin, in the first stage, sequentially separated protein (deproteinization) and mineral (demineralization) components of bee, i.e. translated them into a soluble state and removed. Demineralization carried out under influence of 2M hydrochloric acid for 5 hours at room temperature.Deproteinization carried out by treating the crushed material in presence 1 N sodium hydroxide for 1 hour at 800C. Each process is accompanied by washing the raw material until neutral wash water (pH = 7).
