What Is Hydrolyzed Collagen Peptide Powder and How Is It Produced
Hydrolyzed collagen peptide powder is produced through enzymatic hydrolysis of native collagen sourced from marine and animal raw materials. The process uses food-grade proteases under controlled temperature and pH conditions to break the peptide bonds in intact collagen chains, producing short-chain peptides in the 500–2500 Da molecular weight range. This molecular size allows direct absorption via the intestinal amino acid transport pathway without further digestion, resulting in significantly higher bioavailability than intact collagen protein or standard gelatin.
Our Collagen Peptide Powder 90–98% is produced using advanced enzymatic hydrolysis from premium marine and animal collagen sources, including deep-sea fish skin, cod fish, abalone, bovine, and crocodile collagen. It is produced through advanced enzymatic hydrolysis technology, which breaks down large molecular weight collagen into small molecular fragments. With a molecular weight ranging from 500 to 2500 DAL, this water-soluble collagen peptide is a natural, fat-free, and cholesterol-free protein product with no obvious odor, making it an ideal ingredient for various industrial applications.
These high-purity hydrolyzed collagen peptides offer excellent solubility, low molecular weight, and neutral taste, making them ideal for beauty nutrition, functional beverages, and dietary supplements.

• Deep Sea Fish Skin Collagen Peptide
• Cod Fish Collagen Peptide
• Abalone Collagen Peptide

FAQ
Q: What collagen sources are available, and is marine collagen peptide powder included?
A: We supply five collagen sources: deep-sea fish skin, cod fish, abalone, bovine, and crocodile collagen peptides. Both marine and bovine options are available, covering a full range of application formats and product positioning requirements.
Q: What is the difference between marine collagen peptide powder and bovine collagen peptide powder in terms of absorption and formulation?
A: Marine collagen peptide powder generally has a lower average molecular weight within the 500–2500 Da range, producing a clearer solution in water-based formulations and faster dissolution at cold temperatures. It is the preferred choice for transparent beverages and beauty drink formulations. Bovine collagen peptide powder has higher heat stability and is more cost-efficient at equivalent protein content, making it better suited for gummies, tablets, and capsule formats. Both types contain primarily Type I collagen and provide the same core amino acid profile high in glycine, proline, and hydroxyproline.
Q: What protein content and molecular weight grades are available, and which is recommended for beverage applications?
A: Protein content ranges from 90% to 98% on a dry basis. Molecular weight ranges from 500 to 2500 Da across all grades. For RTD beverages and clear collagen drinks, grades with average molecular weight concentrated below 1,000 Da produce the clearest solution and fastest dissolution at standard inclusion rates of 1%–3%. If your formulation requires a tighter molecular weight range, we can provide custom fractionated grades. Contact our technical team with your target application, and we will recommend the most suitable grade and provide solubility test data in your specific base system.
Q: Is collagen peptide powder suitable for cold-fill RTD beverage manufacturing, and is it compatible with acidic or carbonated systems?
A: Yes. Our hydrolyzed collagen peptides dissolve quickly in cold water without requiring heat treatment, supporting cold-fill production processes. The ingredient is stable in acidic juice bases at pH 3.0–4.5. For carbonated beverages, CO2 retention should be verified at inclusion rates above 2%, as protein concentration can affect carbonation stability in some base systems.
Q: Is collagen peptide powder suitable for vegetarian or vegan formulations, and does it contain common allergens?
A: No. All collagen peptide sources are derived from animal or marine materials and are not suitable for vegetarian or vegan formulations. The product is free from common allergens, including gluten, soy, dairy, and nuts, but derivation from animal sources should be confirmed with your team if specific allergen concerns apply.
Q: What certificates do you hold, and do you offer collagen peptide powder for private label products?
A: We hold ISO22000, BRC, HACCP, KOSHER, HALAL, and FDA certificates. For private label projects, we supply collagen peptide powder across marine and bovine sources with protein content grades from 90% to 98%, supporting custom particle size, flavoring, and packaging specifications. A full OEM documentation package-including COA, allergen statement, Non-GMO declaration, and HALAL/KOSHER certificates-is provided as standard to support retail platform compliance and regulatory filing. Minimum order starts from 1kg for sample evaluation; commercial order lead time is 7–15 business days after specification confirmation.
Q: How long does sample delivery take, and what is the shelf life of the product?
A: Samples are usually shipped within 3–5 business days after the request is confirmed, with delivery time depending on the destination country. The product has a shelf life of 24 months from the date of production when stored in a cool, dry, well-ventilated place away from direct sunlight, sealed after each use.
