Low-Temperature Alpha-Amylase For Alcohol Industry
Introduction
Low-temperature α-amylase is made from the strain of Bacillus subtilis through cultivation, fermentation, and extraction technique. This product can be used for the liquefying process of fruit juice, glucose, cerealose, alcohol, beer, monosodium glutamate, Shaoxing wine, distillate spirits fermentation industry, printing and dyeing industry, as well as the desizing process of the textile industry.
Definition Of Unit
1 unit of low-temperature α-amylase equals the amount of enzyme which liquefies 1g of soluble starch at 60℃ and pH 6.0 in 1h.

Recommended Dosage
For beer industry: The recommended dosage is 0.4-0.8L of the enzyme preparation per ton of total raw materials, added at liquefaction. However, the optimal dosage depends on the composition of the raw materials and the specific process parameters and should be determined by testing different dosages at the brewery.
For alcohol industry: Add this enzyme 0.4-1L per ton of total raw materials with pH 5.0-6.0.
For the fruit juice industry: Improve the transmittance of juice and prevent turbidity. Dosage is 0.02-0.1L/T juice pulp.
Package
Packaging specification: 1 kg / bag.
Storage
Best Before: When stored as recommended, the product is best used within 6 months from the date of delivery.
Shelf Life: 6 months at 25℃, activity remains ≥90%. Increase dosage after shelf life.
Storage Conditions: This product should be stored in a cool and dry place in a sealed container, avoiding insolation, high temperature, and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Safety
Enzyme preparations are proteins, which may induce sensitization and cause allergic-type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes, or nasal mucosa, so any direct contiguity with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
