Keratinase hydrolyzes keratin-rich materials into soluble peptides and amino-acid rich hydrolysates. It is widely used to convert feather, hair, and wool waste into feed-grade proteins, biofertilizers, and value-added cosmetic ingredients.
Hydrolyzes keratin in poultry feathers to convert waste into digestible, high-protein feather meal for animal feed.
Degrades keratin-rich waste from barbershops, wool processing, and slaughterhouses into usable protein hydrolysate.
Transforms keratin waste into nitrogen-rich liquid biofertilizer, providing a slow-release amino acid source for crops.
Produces keratin peptides from feather/wool waste for hair repair, nail strengthening, and skin care formulations.
Studied for degradation of prion proteins, supporting potential research directions for BSE/CJD decontamination of surgical instruments.
Enables waste-to-value conversion of keratin (3rd most abundant biopolymer), supporting zero-waste processing goals.
Supplies Keratinase with activity tailored for keratin azure assay performance, supporting consistent hydrolysis of feathers, hair, and wool.
Optimized for operation in pH 7.0–10.0 and 50°C–70°C, helping you align with alkaline/thermal processing workflows.
ISO 9001 manufacturing with Industrial Grade and Feed Grade options. COA and technical documentation available for qualified inquiries.
Choose 1 kg, 5 kg, or 25 kg formats with MOQ starting at 1 kg—ideal for pilot trials and scale-up planning.
It is used to hydrolyze keratin-rich materials such as 🪶 poultry feathers, 💇 hair and wool waste, and related keratin by-products into soluble peptides/protein hydrolysates for feed, biofertilizer, and cosmetic ingredient applications.
For best performance, operate within pH 7.0–10.0 and 50°C–70°C. Final dosing and exact conditions should be confirmed through your substrate-specific trials.
The range reflects measured enzyme units per gram using the keratin azure assay. Higher activity typically enables faster keratin breakdown at the same dosage; formulation should be optimized for your process.
Keratinase is designed for tough keratin substrates including poultry feathers, hair, and wool-derived materials. It is commonly applied to waste streams from feed, textile, and slaughterhouse operations.
Store sealed in a cool, dry place. The shelf life is 12 months under proper storage conditions; avoid moisture exposure and follow the COA/TDS guidance provided with your shipment.
