Hydrolyzed Fish Collagen
Hydrolysed Fish Collagen is a marine-derived collagen peptide produced by enzymatic hydrolysis of cleaned fish skin and, in some processes, scales. It is positioned as the premium marine peptide for beauty, beverage, and clinical formats where bovine and porcine sourcing are not acceptable.
The peptide pool is dominated by Type I collagen, with average molecular weight typically between 1 and 5 kDa. The finished powder is cold-water soluble, near-clear in solution, and produced with extended deodorisation to meet the sensory expectations of premium ready-to-drink products.
We source bulk Hydrolyzed Fish Collagen from top China manufacturers for our partners. The manufacturer is in Beijing. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Hydrolysed Fish Collagen is graded by molecular weight, by species, and by sensory profile.
Ultra-low MW premium grades around 1 to 2 kDa are produced for clear beverages, shots, sparkling waters, and cosmetic ampoules. Standard 2 to 5 kDa grades cover capsules, sachets, and most beauty-from-within powders.
Species grading separates cold-water marine fish such as cod, pollock, and haddock from warm-water aquaculture species such as tilapia and pangasius. Cold-water grades carry a slightly different amino-acid profile and tend to be priced higher.
Sensory grading distinguishes standard-deodorised material from ultra-deodorised streams polished through extended carbon and ion-exchange treatment for use in unflavored or lightly flavoured products.

How We Help Source Hydrolyzed Fish Collagen
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Hydrolyzed Fish Collagen out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Hydrolyzed Fish Collagen together with other ingredients such as Collagen Peptide, Soy Protein Isolate and Fish Collagen Peptide into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Hydrolysed Fish Collagen is regulated as a food ingredient or supplement protein in most jurisdictions and does not carry a food-additive number.
In the United States it falls under generally recognized as safe practice when produced from edible fish under good manufacturing practice. Fish allergen labelling is required under the Food Allergen Labelling and Consumer Protection Act.
In the European Union general food law, the Regulation EC 853/2004 hygiene rules for collagen of fishery origin, and the mandatory allergen labelling for fish under Regulation EU 1169/2011 all cover it.
Halal and kosher certifications are routinely available where the supply chain is segregated. Pharmacopoeial monographs for hydrolysed collagen apply where fish material is used in pharmaceutical excipients.
Manufacturing Process
Production starts with washed fish skin recovered from filleting operations, with optional scale and frame addition for specific projects. The skin is demineralized with dilute acid to dissolve residual calcium phosphate.
Conditioned skin is extracted with clean hot water at 45 to 70 degrees Celsius, depending on species, to release fish gelatin. Food-grade alkaline or neutral bacterial proteases then cleave the gelatin into peptides of the target molecular-weight band.
The solution is decolorised with activated carbon, deionized through ion-exchange resins, polished to reduce fish odour, ultrafiltered to the specified cut-off, concentrated under vacuum, and spray-dried.
Cold-water species require lower extraction temperatures because their collagen denatures earlier than warm-water material, and process windows are tuned accordingly to preserve yield and colour.
