Description

α-Amylase is a crucial industrial enzyme that catalyzes the hydrolysis of internal α-1,4-glycosidic linkages in starch and related polysaccharides, converting them into smaller dextrins, maltose, and glucose. This efficient biocatalyst is essential for reducing process viscosity, improving yield, and enabling cost-effective production across numerous sectors. It is a fundamental processing aid for manufacturers in the food, beverage, biofuel, textile, and pharmaceutical industries seeking to optimize starch conversion and resource utilization.

Application

• Starch Processing & Sugar Syrup Production: For the liquefaction of starch to produce glucose, maltose, and high-fructose corn syrups (HFCS).
• Baking Industry: Used as a dough conditioner to improve bread volume, crumb structure, and shelf life by generating fermentable sugars.
• Brewing & Distilling: Facilitates the saccharification of grains during mashing to produce fermentable sugars for alcohol production.
• Biofuel Production: A key enzyme in the conversion of starch from corn, wheat, or cassava into fermentable sugars for bioethanol.
• Textile Desizing: Removes starch-based sizing agents from woven fabrics without damaging the fibers.
• Animal Feed: Added to feed to improve the digestibility and nutritional value of starch-containing ingredients.
• Paper & Pulp Industry: Used in the modification of starch for paper coating and as a processing aid.
• Detergent Formulations: Incorporated into laundry and dishwashing detergents to break down starchy stains.

Quality Control

Our α-Amylase is produced and tested under stringent quality management systems. We offer grades compliant with key industry standards, including Food Chemical Codex (FCC) and Kosher certification, suitable for food and feed applications. Every batch is characterized for key parameters such as activity, pH optimum, temperature stability, and microbial limits. Certificates of Analysis (COA) detailing purity, activity (DU, KNU, or FAU), and specification compliance are available upon request to ensure your process consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 2°C and 8°C (refrigerated) for long-term stability, or as specified on the label. This product is hygroscopic (moisture-sensitive). Avoid exposure to high humidity and temperature fluctuations to maintain optimal enzymatic activity and shelf life.
