Application
1.Pharmaceuticals & Joint Health
● Adjunct Therapy for Osteoarthritis: Acts as a precursor for cartilage matrix, promoting glycosaminoglycan synthesis. It helps repair damaged cartilage, reduce joint friction and pain, and alleviate symptoms of osteoarthritis and rheumatoid arthritis.
● Anti-inflammatory & Immunomodulation: Inhibits inflammatory cytokines such as IL-1 and TNF-α, regulates glycoprotein synthesis in immune cells, and enhances overall immunity.
2.Cosmetics & Oral Beauty
● Moisturizing & Anti-aging: Stimulates the skin to synthesize hyaluronic acid, improves the water-retention capacity of the stratum corneum, reduces dry and fine lines, and enhances skin elasticity and fullness.
● Barrier Repair: Maintains the integrity of the skin barrier, promotes the repair of damaged skin, and soothes sensitivity.
● Whitening & Spot Reduction: Inhibits melanin production, improving dullness, acne marks, and pigmentation.
● Applicable Forms: Serums, creams, face masks, and oral beauty drinks.
3.Food & Dietary Supplements (New Food Raw Material)
● Regulatory Status: Approved as a New Food Raw Material by the National Health Commission of China in August 2024, with a daily consumption limit of ≤500mg.
● Applications: Used in dairy products, beverages, jelly, candy, and pastries as a functional additive, stabilizer, or sweetener (suitable for diabetics).
● Gut Health: Maintains the intestinal mucosal barrier, promotes intestinal repair, and regulates gut flora.
4.Industry & Fine Chemicals
● Pharmaceutical Intermediates: Used in the synthesis of antibiotics, antiviral drugs, and immunomodulators.
● Biomaterials: Used for the preparation of chitosan, medical dressings, and tissue engineering scaffolds.
● Others: Electroplating additives, textile auxiliaries, and feed additives.
