Low temperature Alpha-amylase Sunson® LTAA

 

PRODUCT DESCRIPTION
Low-temperature α-amylase (AAL) is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation.  The product is not as heat-stable as thermostable α-amylase, bringing the benefit of easy inactivation.   

MECHANISM 

This product belongs to family of hydrolytic enzyme, attacking α-1.4 glycosidic bond in starch, glycogen, etc., producing dextrin, oligosaccharides a small amount of glucose.

  APPLICATION RECOMMENDATION 

l  Brewing industry: The recommended dosage is 0.4-0.8L of the enzyme preparation per ton of total raw materials, added at liquefaction.  

l  For alcohol industry: Add 0.4-1L per ton of total raw materials with pH 5.0-6.0. 

l  Fruit juice industryThe recommended dosage is 0.02-0.1L/T fruit.   

The dosage has to be optimized based on each application, the raw material specifications, product expectation and processing parameters. It is better to begin the test with the convenient volume.  

SAFE HANDLING PRECAUTIONS 

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.  

WARNINGS 

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
