PRODUCTION METHOD OF ENVIRONMENTALLY FRIENDLY CHITOSAN FROM ACRIDIDAE, TENEBRIONIDAE AND GAMMARIDAE FAMILIES

摘要

The invention relates to the production method of environmentally friendly - in terms of both chemical issues and energy - chitosan from Acrididae, Tenebnonidae and Gammaridae families, which are less likely to contain toxic or heavy metal compounds. The invention is the production method of environmentally friendly chitosan from Acrididae, Tenebrionidae and Gammaridae families, characterized by comprising the process steps of making dead organisms of Acrididae, Tenebrionidae and Gammaridae families into powder form, pre-treatment, removing lipids and soluble proteins, demineralization, deproteinization, depigmentation, deacetylation, and removing chitin in order to increase purity.
