Properties

Unlock cleaner, faster, and more sustainable protein processing with our industrial & food-grade keratinase - a high-performance enzyme designed to efficiently break down tough keratin structures in feathers, hair, and other resilient protein materials. Ideal for animal by-product valorisation, feed and pet food ingredient upgrading, collagen/peptide production, and protein hydrolysate applications, this keratinase delivers rapid hydrolysis under practical processing conditions, helping reduce harsh chemicals, shorten processing times, and improve yield of soluble proteins and amino acids.

Produced under strict quality standards with consistent activity and reliable batch-to-batch performance, it’s a cost-effective solution for manufacturers looking to boost functionality, digestibility, and sustainability - turning difficult waste streams into high-value, market-ready ingredients.

Reaction

Keratin + H2O → Keratin Peptides and Amino Acids CAS Number: 9025-41-6

Storage

12 months * Where 1 unit of activity is the amount of enzyme required to release 1 μmol of tyrosine-equivalent molecules per minute under defined conditions
