Why are some oral liquids and functional foods selling so well?
The answer often lies in the raw materials. Sichuan Shihong Technology Co., Ltd. brings you food grade bovine hide collagen peptides – small molecule, easy to absorb, high purity – designed for beauty drinks, joint care foods, protein snacks, and more. Help your products seize the dual opportunities of the “beauty economy” and the “wellness trend.”

• Molecular weight ≤3000 Da – absorbed directly without decomposition, far superior bioavailability compared to high-molecular-weight collagen

• Hydroxyproline ≥9.86% (measured) – far exceeds the national standard requirement of ≥3%

• Protein (dry basis) ≥97%, ash ≤0.45% – very low impurities, clean taste

• Heavy metals not detected (Hg/As/Cd/Pb), chromium only 0.35 ppm – well below regulatory limits

• Strict enzymatic hydrolysis + multi-stage desalting and decolorization – no peroxide bleaching, no sulfur dioxide – safe and compliant

Note: Measured data from the batch of January 2026 (COA). Each batch undergoes strict quality inspection.

1. Fast Absorption, Clearer Efficacy
Molecular weight is controlled at about 3000 Da, far lower than the national standard limit of 10000 Da. The product can be directly absorbed into the bloodstream without gastrointestinal breakdown, targeting skin, bones, and joints.
Hydroxyproline content reaches 9.86% (dry basis) – a hallmark amino acid of collagen – the higher the content, the more authentic the purity.

2. Clean, Neutral Taste – Formulator Friendly
Multi-step activated carbon decolorization + ion exchange desalting results in ash content of only 0.45% and extremely low heavy metal residues.
Flavor enzymes are added during production – no fishy or bitter taste. Ideal for products with high flavor requirements such as oral liquids, solid beverages, and gummies.

3. Safe, Compliant – No “Industrial Waste”
Raw material is fresh bovine hide – absolutely no chromium-containing tannery waste. Chromium content is only 0.35 mg/kg (national standard allows 2.0).
No peroxide bleaching, no sulfur dioxide sterilization – fully compliant with GB 31645-2018 and food additive requirements.
