Sufficient supply of raw materials and broad prospects for the development and utilization of silkworm pupa chitin

Silkworm pupa chitin is a natural polymer compound extracted from pupa shell and pupa skin. Silkworm chrysalis chitin is rich in protein, oil, pigments and other ingredients, and has high development value. In addition, silkworm chrysalis chitin has various biological activities such as anti-aging, anti-fatigue, preventing cardiovascular disease, lowering blood lipids, antibacterial, and anti-tumor. It can be used as a hemostatic material, nutritional supplement, antibacterial agent, etc. in medicine, food, health products, It has broad application prospects in sanitary products, chemicals, fibers, dyes and other fields.

According to the “2023-2028 Silkworm Chrysalis Chitin Industry Market In-depth Research and Investment Prospects Forecast Analysis Report released by the Industrial Research Center, The raw material of silkworm chrysalis chitin is mainly silkworm chrysalis. my country has a long history of planting mulberry and raising sericulture. The current area of ​​mulberry orchards nationwide is about 12 million acres. In recent years, my country’s main sericulture production areas have gradually shifted from the eastern region to the western region. The western region represented by Guangxi, Sichuan, Guizhou, and Yunnan has It has become the largest sericulture production base in my country. Silkworm chrysalis is the main by-product of the sericulture industry. In recent years, with the improvement of deep processing technology, the utilization rate of silkworm chrysalis resources has gradually increased, and products such as silkworm chrysalis protein, silkworm chrysalis protein peptides, silkworm chrysalis oil, and silkworm chrysalis chitin have gradually entered the market.

Silkworm chrysalis is one of the ways to obtain chitin. In recent years, there have been many research documents on silkworm chrysalis chitin in my country, including “Research Progress on the Application of Silkworm Chrysalis Chitin in the Field of Medicine and Chemical Industry”, “Preparation and Deacetylation of Silkworm Chrysalis Chitin” Modification Research”, “Preparation and Performance Research of Silkworm Chrysalis Chitin Nanofiber Membrane”, “Study on the Adsorption Properties of Silkworm Chrysalis Chitin to Heavy Metal Ions”, “Preparation of Silkworm Chrysalis Chitin/Chitosan Nanogel and Research on Drug Carriers “wait. The literature covers the preparation, characteristics, and application of silkworm pupa chitin, providing important reference for the development and utilization of silkworm pupa chitin.

Chitin is a polysaccharide substance mainly derived from the shells of marine crustaceans. my country is a major producer and exporter of chitin. In 2022, the scale of my country’s chitin market will be about 7 billion yuan. The main manufacturers include Zhejiang Jinke Pharmaceutical, Weifang Kehai Chitin, Qingdao Jifa Group, etc. Chitin has a wide range of applications, involving medicine, pesticides, fibers, cosmetics, dyes and other fields. As a kind of chitin, silkworm chrysalis chitin also has broad application prospects in the medical field, such as the preparation of drug carriers, sutures, hemostatic materials, medical chitosan, etc.

Industry analysts said that the production scale of silkworm chrysalis chitin is mainly affected by factors such as raw material supply, production technology, market demand, etc. Vegetable production involves acid immersion, alkali immersion, oxidative decolorization, deacetylation and other links. my country is rich in silkworm pupa resources, and the development of the silkworm pupa chitin industry has raw material advantages. Silkworm pupa chitin has a variety of biological activities. As research continues to deepen and market recognition increases, the demand for silkworm pupa chitin applications will grow.
