Acid Protease Enzyme Powder
50,000 – 100,000 U/g
Acid protease works optimally at pH 2.0–5.0, making it ideal for acidic processing environments.
Boosts ethanol yield in baijiu, whisky, and fuel ethanol production by breaking down grain proteins during fermentation.
Improves wort clarity, reduces haze, and enhances protein utilization in beer production.
Increases protein digestibility in feed formulations, improving FCR and reducing feed costs.
Produces bioactive peptides and amino acids from plant and animal proteins for food and pharma.
Accelerates protein breakdown in fermented condiment production, improving flavor development.
Enzymatic bating and dehairing at acidic pH ranges, replacing harsh chemicals.

No middlemen. We manufacture acid protease at our own facility, so you get competitive pricing at any volume.
Every batch is tested for enzyme activity, moisture, particle size, and microbial limits before shipping.
Our enzyme engineers help you optimize dosage, pH, temperature, and process conditions for your specific application.
Custom packaging from 1 kg samples to 25 kg drums to 1 MT bulk bags. Private labeling available.
Acid protease is primarily used in alcohol fermentation (baijiu, whisky, fuel ethanol), brewing, soy sauce production, animal feed, and protein hydrolysis. It works at low pH (2.0–5.0), making it ideal for acidic processing environments.
Our MOQ is 25 kg (one drum). We also provide free samples (typically 100–500g) for testing before you commit to a bulk order.
Yes, we ship worldwide via sea freight, air freight, or express courier (DHL/FedEx). Typical delivery is 7–15 business days depending on destination.
Absolutely. Fill out the contact form below and we will send a free sample with a certificate of analysis (COA) and technical data sheet (TDS).
Our facility is ISO 9001 certified. Our acid protease products are available with HALAL, KOSHER, and food-grade certifications depending on the grade selected.
