{“@context”:”https://schema.org”,”@type”:”FAQPage”,”mainEntity”:[{“@type”:”Question”,”name”:”What is protease enzyme used for?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Proteases hydrolyze proteins into peptides and amino acids. Industrial applications include: brewing (chill-haze prevention, improved filtration), food processing (protein hydrolysates, flavor development), animal feed (improved amino acid digestibility), leather bating and dehairing, detergent protein stain removal, and industrial protein processing.”}},{“@type”:”Question”,”name”:”What is the difference between acid, neutral, and alkaline protease?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Acid protease (optimum pH 2.5–4.5, from Aspergillus niger) is used where low pH conditions apply — brewing, gastric simulation, beverage clarification. Neutral protease (pH 6–8, from Bacillus subtilis) suits food and feed applications. Alkaline protease (pH 8–11, from Bacillus licheniformis) is ideal for detergents, leather, and industrial applications.”}},{“@type”:”Question”,”name”:”What protease activity levels do you supply?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”We supply protease powder up to 400,000 U/g and liquid protease up to 150,000 U/mL. Activity is expressed in U/g (acid protease), HUT/g (haemoglobin units), or AU/g depending on the grade. Multiple CAS numbers apply: acid protease (9025-49-4), alkaline protease (9014-01-1), neutral protease (9040-76-0). Technical data sheets with assay protocols are included with every order.”}},{“@type”:”Question”,”name”:”Can protease be used for brewing chill-haze prevention?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Yes. Acid and neutral proteases are widely used for brewing chill-haze prevention. The enzyme is typically added during maturation or cold conditioning to hydrolyze haze-forming polypeptides. This extends beer shelf life and improves clarity without affecting foam stability when used at correct application rates.”}},{“@type”:”Question”,”name”:”Is protease safe for food applications?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Yes. Our food-grade protease preparations are manufactured by controlled fermentation of food-safe organisms (Aspergillus niger, Bacillus subtilis, Bacillus licheniformis) and comply with food additive requirements. Certificate of analysis confirming activity, microbiological specifications, and absence of relevant contaminants ships with every batch.”}},{“@type”:”Question”,”name”:”Can I order a small sample before buying in bulk?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Yes. Minimum order is 1 kg. This is sufficient for lab trials, pilot processing, and small-batch production. Same specification at all order sizes. Certificate of analysis and technical data sheet included with every shipment.”}}]}
