The silk fibroin industry has huge development potential, and domestic and foreign companies have increased

According to different sources, silk fibroin is divided into two categories: natural silk fibroin and regenerated silk fibroin. Regenerated silk fibroin is mainly produced from silkworm cocoons through degumming, dissolution, dialysis, and modification operations. Silk fibroin preparation methods include methanol recrystallization method, natural drying and hot pressing molding method, Cisco improved methanol recrystallization method, etc.

Silk fibroin, also known as silk protein and silk peptide powder, is a natural polymer fiber protein extracted from silk. According to different solubility, silk fibroin can be divided into two categories: soluble silk fibroin and insoluble silk fibroin. Silk is mainly composed of two proteins, sericin and silk fibroin, of which silk fibroin has the highest content, accounting for about 75%.

According to the “2023-2027 Silk Firin Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, the Thanks to strong market demand and advancements in extraction technology, global sales of silk fibroin continue to grow, reaching more than 670 tons in 2022. my country is the world’s largest consumer of silk fibroin. In 2022, my country’s silk fibroin market will reach more than US$10 million, accounting for approximately 30% of the global market.

As a natural polymer material, silk fibroin has good biocompatibility, biodegradability, mechanical properties, etc., and has broad application prospects in the fields of cosmetics, textiles, medical care, bioengineering, and medical beauty. In the field of cosmetics, powder, solution and gel products made of silk fibroin have moisturizing, film-forming, whitening and anti-aging properties and can be added to shampoo, hand sanitizer, moisturizer and other products; in the medical field, Silk fibroin has good blood compatibility and can be made into hernia repairs, dressings, artificial blood vessels, artificial cartilage and other products. It has broad application prospects in the fields of skin regeneration, heart valves, orthopedics, trauma treatment and other fields.

Based on its broad application prospects, the number of companies entering the silk fibroin market continues to increase globally. At present, the global silk fibroin production capacity is mainly distributed in China, Europe and other regions. my country is the largest silk fibroin producer in the world. The main domestic production companies include Jiangxi Silk Biotechnology, Huzhou Xintence, Xi’an Chengwen Biotechnology, Zhejiang Wuwu Biotechnology, etc.

As a new type of natural medical material, silk fibroin has great development potential. In order to promote its rapid development and application, the Chinese government has also issued a series of favorable policies in recent years, such as the “Guidance Catalog of Key Products and Services for Strategic Emerging Industries”, “Tissue engineering medical device silk fibroin” (Draft for comments), “The 14th Five-Year Plan for Bioeconomic Development Plan”, etc. Under the guidance of policies, the silk fibroin market will usher in a stage of rapid development.

Industry analysts said that foreign silk fibroin-related companies include Sofregen Inc., Evolved by nature Inc., Cocoon Biotech Inc., etc. . In recent years, with the active exploration of domestic and foreign companies, the types of silk fibroin-based products have become increasingly rich, and the application fields of silk fibroin have also continued to expand, and the industry has shown vigorous development momentum. In the future, as relevant standards are improved and preparation processes are improved, the scale of the silk fibroin industry will further expand.
