Collagen peptides (bovine)

Collagen peptides are made by controlled enzymatic hydrolysis of bovine collagen, taken either from hide splits or from ossein recovered by acid demineralisation of bovine bone, which is the route most Indian producers run. Hydrolysis cuts the gelatin chain down to short peptides averaging 1,000–3,000 Da, and that is why the powder disperses in cold water and never sets to a gel. Assay is above 94% protein on dry matter by Kjeldahl using the collagen factor N x 5.55. Hydroxyproline is reported on the certificate as the identity marker; mammalian collagens run roughly 13–14% hydroxyproline, and that figure is what separates a genuine collagen hydrolysate from a generic protein hydrolysate. For formulators the value sits in what collagen peptides do not do. A 10% solution measures around 2.0 mPa·s with turbidity under 50 FTU, so a beverage developer can load 10–15 g per serve without picking up body or haze, which is not possible with most proteins. The material tolerates pasteurisation, low pH and high sugar, and instantised granulate grades wet out in a shaker without lumping. The composition is unusual rather than complete: glycine occupies roughly every third residue and proline plus hydroxyproline about one sixth of the sequence, while tryptophan is absent altogether. Collagen peptides are therefore formulated alongside a complete protein rather than as the sole nitrogen source. Origin declarations matter on this one. The material is bovine and is not vegan, vegetarian or porcine; it carries none of the major food allergens, halal certification is routine on Indian cattle and buffalo material, and kosher status depends on the specific source approval. Export from India sits under DGFT Schedule 2 entry 173 at ITC-HS 35040010, which names collagen peptides of bovine origin explicitly. Shipments move freely, but consignments to the European Union additionally require a Shipment Clearance Certificate issued consignment-wise by CAPEXIL together with a health certificate from the Animal Quarantine Officer. Every lot ships with CoA, allergen and TSE/BSE statements, nutritional and amino acid data, MSDS and specification sheet.
