Medium Temperature Alpha Amylase Enzyme (Powder) | SENTIANBIO
Use: starch liquefaction, brewing/distilling, food processing, and textile desizing.
Product Overview
What it does
α-Amylase is an endo-acting enzyme that breaks internal α-1,4 glycosidic bonds in starch, helping liquefy gelatinized starch and generate soluble dextrins/fermentable sugars. “Medium temperature” commonly targets controlled processing around 60–70°C.

Technical Specifications
Commercial baseline (from SENTIAN listing)
Code: ST-amylase enzyme. Other name: Diastase. Form: white powder. Activity option: 10,000 U/g. Docs: MSDS & COA. Shelf life: 2 years. Storage: cool & dry. Sample: 10–20 g. MOQ: 1 kg. Packaging: 1 kg/bag; 25 kg/drum. Incoterms: FOB/CIF/EXW/DDP. Shipping: ocean/air/express.
Typical mid-temp α-amylase process window (reference)
- pH: often near 6.0 (commonly stable around pH 6.0–7.0; weak below pH 5.0)
- Temperature: typically effective around 60–70°C (process-dependent)
- Ca2+: calcium may be required/beneficial for stability in many systems
Always validate dosage and unit definition (U/g, BAU, IU, etc.) using your pilot trial + the latest COA/TDS.

Product Features
Key advantages
- Liquefaction support: helps reduce mash/slurry viscosity for smoother mixing and pumping.
- Process control: designed for mid-temperature operations where extreme high-temp enzymes may be unnecessary.
- Export-friendly: powder form suits bulk shipment and precise dosing.
How to Use
Recommended workflow
- Prepare and gelatinize starch slurry according to your SOP.
- Adjust pH toward the enzyme’s optimum (often near pH 6.0 for mid-temp α-amylase).
- Ensure Ca2+ availability if your system requires it.
- Pre-disperse powder in water and dose with strong agitation to avoid lumps.
- Hold at target temperature (commonly 60–70°C) for the designed residence time.
- Proceed to saccharification/fermentation, or inactivate per HACCP needs.
Application Scenarios
Where buyers use it
- Starch sugar/syrup lines (liquefaction support)
- Brewing & distilling (starch-to-sugar conversion)
- Food processing (cereal/starch hydrolysis)
- Textile desizing (starch removal from fabric)
Benefits for Customers
Commercial outcomes
- Shorter processing time and more stable viscosity control
- Better filtration/fermentation consistency (process-dependent)
- Smoother QA onboarding with MSDS/COA support

FAQ
What is the MOQ and sample policy?
MOQ: 1 kg. Sample: typically 10–20 g for evaluation (policy depends on destination and logistics).
How do I choose medium-temperature vs high-temperature α-amylase?
Select based on your liquefaction temperature profile. Mid-temp products are typically used around 60–70°C, while heat-resistant types are selected when operating around ~90°C or higher.
How should I store and handle enzyme powder?
Store sealed in a cool, dry place. Avoid inhaling dust and follow your SDS and internal EH&S SOP.
