СПОСОБ ПОЛУЧЕНИЯ ХИТОЗАНА ИЗ ХИТИНА РАКООБРАЗНЫХ

摘要

FIELD: fish industry. ^ SUBSTANCE: method involves providing deacetylation of raw material with the use of preliminarily cooled alkaline solution; washing and drying. Deacetylation process is performed in three stages, first stage being performed for 7 days and subsequent two stages being performed for 2 hours each, combined with thermal processing at temperature of 55-590C. Washing process is provided after each deacetylation stage. ^ EFFECT: provision for producing of chitosan from chitin of cancerous with increased extent of deacetylation, while native properties of natural polymer being kept, without breaking of glycoside binding chain. ^ 3 ex
