APPLICATION RECOMMENDATION 

Ø  Reaction parameters

 Ø  Application

Temperature: 10-80℃, optimum: 40-50℃

pH: 2.0-10.0, optimum5.0-8.0

Liquor ratio: 5:1-20:1

Dosage: 0.05-0.3% owg (after dilution)

Time: 10-20 minutes

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. 

Ø  Inactivation

The enzyme is inactivated at temperature above 100℃ for 10 minutes, or at pH above 12.0 for 10 minutes. 

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.
