Food-Grade Alpha Amylase for Rice Wine Processing
Food-grade α-amylase is a high-activity enzymatic preparation specifically developed for rice wine and traditional grain-based alcoholic beverage production. The enzyme efficiently hydrolyzes starch by cleaving α-1,4 glycosidic bonds, converting gelatinized starch into dextrins and fermentable sugars that support stable and efficient fermentation.
This product is optimized for applications such as rice wine, yellow wine, and grain-based distilled spirits, where controlled starch liquefaction and sugar generation are critical to product quality, fermentation consistency, and yield. Its high enzymatic efficiency helps improve saccharification performance while supporting balanced flavor development in the final beverage.
Key Functional Characteristics
- Rapid starch hydrolysis with high enzymatic activity
- Improves fermentable sugar availability during saccharification
- Enhances fermentation stability and process efficiency
- Suitable for rice and other cereal-based raw materials
- Food-grade quality for beverage and fermentation applications
Recommended Application Areas
- Rice wine production
- Yellow wine processing
- Grain-based alcoholic beverage fermentation
- Starch saccharification in brewing and fermentation industries
Usage Method
The recommended dosage is 0.1–0.5% based on raw material weight. α-amylase is typically added during the saccharification stage and mixed thoroughly with the cooked or gelatinized grain substrate.
Due to variations in raw material composition and processing conditions, the optimal dosage and addition method should be determined through preliminary trials.
