Abstract
The introduction presents scientific data on the structure, chemical composition and properties of chitin, chitosan and the chitin-glucan complex. In recent years, special attention has been paid to the biopolymer chitin and its derivatives. Due to their unique properties: biocompatibility, biodegradability, non-toxicity, they have found application in more than 70 areas: medicine, ecology, food industry, agriculture. Sources for the production of chitin can be the shell of commercial crustaceans, the biomass of fungi, and the cuticle of insects. The main part describes the modern fields of application of these biopolymers and raw materials for the production of chitin and its derivatives. At present, interest has increased in the problems of more rational use of renewable natural resources, both from an environmental and economic point of view. There are various biopolymers in the world, in particular, the biopolymer of the 21st century – chitin and its derivatives. The recommended daily intake of chitin is from 3 to 7 g. The consumption of such an amount of chitin or chitosan is used to remove toxins and harmful substances, radionuclides, and pathogenic microorganisms from the body. On the industrial scale of the Republic of Belarus, fungi, insect carrion, earthworms can serve to isolate chitin and its derivatives. Due to the fact that on the industrial scale of the Republic of Belarus, the use of crustaceans as a source of chitin for the Republic of Belarus is very costly. In addition, a negative factor is the increase in pollution of sinks with heavy metals and other toxic waste.
