Abstract: The enzymatic lactase processed low lactose milk powder and the hydrolysis optimal conditions were studied. The results showed that amount of lactose added 0.8 g/L, the hydrolysis temperature 10 ℃, time 8 h, pH 6.6~6.8 and lactase hydrolysis rate above 60% without increasing the microbial count in the milk. And a new low lactose milk powder product is produced.

Key words: milk, lactase, low lactose milk powder
