INTRODUCTION (abstract of doctor of philosophy (PhD) thesis) 
 
The aim of research work development of an advanced technology for the 
production of chitin and chitosan from the silkworm waste of the silk industry and, 
on the basis of it, to create a technology for the production of a biologically active, 
environmentally friendly preparation "UZKHITAN". 
The object of research work silkworm pupae, chitin, chitosan and 
environmentally friendly, biologically active preparations "UZKHITAN" on its 
basis. 
Scientific novelty of the research work is consisted in follows: 
for the first time, a perfect integrated technology for extracting chitin and 
chitosan from silkworm waste was created; 
the dependence of the physicochemical properties of chitin and chitosan on 
the technological parameters was determined and the optimal conditions for the 
production technology were found; 
for the first time a technology was developed for the production of an 
ecologically safe, biologically active drug "UZKHITAN", which is used for 
encapsulation of agricultural seeds based on chitosan, and the optimal 
technological conditions were determined. 
Implementation of research results. Based on the results obtained on the 
development of a technology for producing chitin and chitosan from silk waste: 
The drug "UZKHITAN" is used in the processing of silkworms of the varieties 
"Uzbekistan-5" and "Uzbekistan-6" and their feed (reference from the Association 
"Uzbekipaksanoat" № 4-2/1499-dated July 30, 2020). As a result, it allowed to 
increase the vitality and productivity of the silkworm. 
The drug "UZKHITAN" is approved by the State Commission of the 
Republic of Uzbekistan on Chemistry and Plant Protection for pre-sowing 
treatment of agricultural seeds. (List of chemical and biological protection agents, 
defoliants and plant growth control agents permitted for use against pests, diseases
