I. Brief Introduction:

Alpha-Amylase is made of Bacillus Subtilis in the Fermentation and extraction method, is widely used in the liquefaction of starch sugar, alcohol, beer, monosodium glutamate, animal feed, Fermentation industries and textile, printing & dyeing, de-sizing and etc.

II. Characteristics:

1. Heat stability: Stable at 60°C or below; Optimum operational temperature 60 -70°C; Applicable to the liquefaction process of 90°C (highest).

2. pH Stability: More stable at pH6.0-7.0; Optimum operational pH below pH6.0; Serious inactive in pH5.0

III. Physical Properties:

1. Specifications: Solid type: 2000u/g~10,000u/g; Liquid type: 2000 u/ml~5000 u/ml.

2. Definition of enzyme activity: One gram of solid alpha-amylase powder ( or one milliliter of liquid alpha-amylase) at 60°C and pH6 liquefies 1 mg of starch in one hour is defined as one enzyme activity unit and marked with u/g or u/gml.

3. Industrial Standard: GB/T 24401-2009.

IV. Usage and Reference Dosage:

1. Manufacture in Maltose, monosodium glutamate: 6-8 u/g of material.

2. Beer brewing: add 6 u/g of the enzyme and keep at 85-90°C for 30 mins.

3. Textile de-sizing: 0.2% (2000 u/g) and keep at 85-90°C for 30 mins. (It is suitable for the material which can not withstand high temperature such as the silk, chemical fiber, woven fabric of cotton, wool and etc.)

4. Other Industries: 6-8 u/g per gram of starch and the concentration of calcium ion is 150ppm.

V. Storage:

Should be stored in a cool, dry and well-ventilated place; protect from direct sunlight, heat and dampness; avoid storing with poisonous and harmful substances. 

VI. Packaging:

20kg/bag, 25 kg/bag ,25kg/drum, 30 kg/drum or as clients' requirements.

VII. Shelf Life:

12 months, subject to storage condition.

IX.Precautions:

Enzyme preparations belong to protein, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.
