Fish Collagen Peptide
Fish Collagen Peptide is a low-molecular-weight protein ingredient produced by enzymatic hydrolysis of skin, scales, and bones of farmed or wild marine fish, most commonly tilapia, pangasius, cod, and pollock. The peptide pool is almost exclusively Type I collagen, mirroring the dominant collagen of mammalian skin.
Average molecular weight typically sits between 1 and 5 kDa, giving the powder cold-water solubility and a clean profile suitable for clear beverages. Fish sourcing also bypasses bovine and porcine restrictions for kosher, halal, and pescatarian consumers.
We source bulk Fish Collagen Peptide from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Shandong, Guangdong and Fujian. 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
Fish Collagen Peptide is graded by molecular weight, by raw material, and by sensory profile.
Premium ultra-low MW grades in the 1 to 2 kDa range carry minimal fish odour and are positioned for clear beauty drinks and shots. Standard 2 to 5 kDa grades suit capsule, sachet, and powdered-mix formats.
Material is split between freshwater fish (tilapia, pangasius) and cold-water marine fish (cod, pollock, salmon). Cold-water grades are often preferred for clinical and pharmaceutical work because of their lower transition temperature and clean amino-acid profile, while freshwater grades dominate cost-sensitive supplement volumes.
Sensory grades distinguish standard-deodorised material from premium ultra-deodorised streams produced by extended carbon and ion-exchange polishing.

How We Help Source Fish Collagen Peptide
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 Fish Collagen Peptide 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 Fish Collagen Peptide together with other ingredients such as Collagen Peptide, Soy Protein Isolate and Gelatin into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Fish Collagen Peptide is regulated as a food ingredient or supplement protein in most major markets 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. Allergen labelling for fish is required under the Food Allergen Labelling and Consumer Protection Act.
In the European Union general food law covers it, together with the hygiene requirements in Regulation EC 853/2004 for collagen of fishery origin. Fish is one of the fourteen mandatory allergens listed in Annex II of Regulation EU 1169/2011.
Halal and kosher certifications are routinely available for fish-derived material when produced on segregated lines. Pharmacopoeial reference monographs for hydrolysed collagen apply where fish material is used in pharmaceutical excipients.
Manufacturing Process
The starting material is fish skin, scales, or a mixed frame fraction recovered from filleting plants. The tissue is washed to remove residual meat, fat, and pigment, then demineralized with dilute acid to dissolve calcium phosphate from scales and bone fragments.
Conditioned tissue is heated in clean water to release fish gelatin, which is then hydrolysed with food-grade proteases such as alkaline or neutral bacterial enzymes. Hydrolysis time, enzyme dose, and ultrafiltration cut-off determine the final molecular-weight distribution.
The peptide solution is decolorised with activated carbon, deionized through ion-exchange resins, polished to reduce fish odour, concentrated under vacuum, and spray-dried to a fine white or off-white powder.
Cold-water and warm-water species require different process windows because their collagens have different denaturation temperatures, with cold-water collagen melting closer to 15 degrees Celsius and tilapia collagen near 35 degrees.
