Definition of unit
u/mL,   1 unit of low-temperature alpha-amylase equals to the amount of enzyme which hydrolyzes soluble starch at 60 ºC and pH 6.0 in 1 hour.
(*) Activity of the enzymes is expressed in u/ml against an internal standard to ensure manufacturing lot-to-lot consistency. The enzyme activity value is not a measure for application performance. A detailed assay method is available upon request.

Storage
Should be stored in a dry place with temperature of 25℃. 

Packaging 
30 kgs/drum

Shelf life
12 months, subject to storage condition.

Safety
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, consult a doctor.
