Product Description

Medium Temperature Alpha Amylase is said to find most common application for processing of sugar, glucose, beer, & alcohol. It is also said to be used in textile & pharmaceutical industries. This enzyme is used for hydrolyses of starch & glycogen for yielding glucose & maltose. It is completely free from any impurities and assures superior effectiveness. Offered Medium Temperature Alpha Amylase is delivered in non-toxic & moisture proof packaging so as to ensure safe transportation & storage.


  • Stable pH value of 6.0-6.5
  • Excellent quality
  • Serves as desizing agent for textile industry


The medium-temperature α-amylase is extracted by Bacillus amyliquefaciens No. BF7658 after liquid culture and fermentation, and can efficiently catalyze the hydrolysis and hydrolysis of starch.

This product is suitable for the “liquefaction” process of glucose, sugar, alcohol, beer, monosodium glutamate, rice wine, liquor, antibiotics, etc. It can also be used in the “desizing” process of the textile industry.

Definition of enzyme unit:

A medium temperature alpha-amylase unit refers to 1 gram of solid enzyme powder (or 1 ml of liquid enzyme), and liquefies 1 gram of soluble starch in 1 hour at 60 ℃ and pH 6.0.


Non-toxic plastic bucket, 25kg/barrel


Store at low temperatures to avoid high temperatures.

Period of validity:

At 25 ℃, 3 months, the enzyme activity remained ≥ 90%. If this period is exceeded, the dosage should be increased appropriately.


6-10 u/g starch raw material.

Safety Precautions:

Enzyme preparations are proteins that can trigger allergies or allergic reactions in some people. Prolonged contact may cause discomfort to the skin, eyes and nasal mucosa. Therefore, any spillage or even a small amount of spillage should be cleaned up in time. The enzyme solution on the skin or eyes should be washed immediately with water and seek the guidance of a specialist.
