Dosage
For steamed bread producing：The recommended dosage is 5-10g per ton of flour. The optimal dosage depends on the quality of flour and the processing parameters and should be determined by steaming test. It is better to begin the test from the smallest quantity. Overuse will decrease the water holding capability of dough.
For bread producing: The recommended dosage is 10-30g per ton of flour. The optimal dosage depends on the quality of flour and the processing parameters and should be determined by baking test. It is better to begin the test from the smallest quantity. Overuse will decrease the water holding capability of dough.

Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in sensitized individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
