High Purity Low Molecular Weight Bovine Collagen Peptide – Food Grade for Nutraceutical, Cosmetic & Medical Use
Bovine Hide Collagen Peptide is manufactured by Sichuan Shihong Technology Co., Ltd. using fresh, quarantine‑approved bovine hides as raw material. Through enzymatic hydrolysis, multi‑stage purification and spray drying, the product achieves a molecular weight below 3000 Da. It features high protein content, low ash, and near‑zero heavy metal residues, making it suitable for a wide range of applications in food & beverage, dietary supplements, medical materials, and premium cosmetics.
