Abstract

The article presents the results of the synthesis of chitin and chitosan biopolymers from a new promising source - the local submersion of Apiss mellifera bees. In work the dried up to 5-7 % and the size of particles up to 0,1-0,3 mm the crushed subsea is used. We have established that the amount of protein and mineral samples of bee subfreezing is stable and does not depend on the place of origin, time and year of collection, which allowed us to develop a common technology for the synthesis of chitin and chitosan from it. Another biologically active substance, melanin, was identified as a contiguous product with chitone. Melanin was precipitated from hydrolysates using 33% hydrochloric acid.
