1. PRODUCT OVERVIEW

This product is produced by submerged fermentation of a selected microbial strain followed by purification, formulation and drying. Lactase is mainly used in dairy industry to relieve people suffered from lactase deficiency while still enjoying dairy products, but also widely used in food, medicine, environmental protection and other fields.

‌2. PRODUCT ADVANTAGE
