A buyer's guide to collagen peptides: how bovine, fish, and Type II chicken collagen differ, why the hydrolyzed form wins in formulations, and how to source it with the right specs and documentation.

Industrial gelatin — often called animal glue — is one of the oldest bonding and structuring materials still in large-scale use. Far from being a legacy product, demand is quietly reshaping around sustainability, traditional manufacturing, and specialized industrial niches. This briefing covers what buyers and formulators need to know in 2026.

For food, nutrition, capsule and selected industrial buyers, choosing the right gelatin, collagen, pectin or empty capsule depends on application, source, specification, dosage target and documentation requirements.

Industrial gelatin (also called technical gelatin) is one of the most versatile natural polymers in modern manufacturing. Derived from the partial hydrolysis of collagen — the same structural protein found in animal hides, bones, and connective tissues — it serves as a binder, adhesive, sizing agent, stabilizer, and protective colloid across 40+ industrial sectors.

Enzymes are proteins — and proteins need nitrogen. Here is why peptone is the nitrogen source of choice for enzyme preparation, and how to use it right.
