摘　　要：应用乳糖酶生物技术生产低乳糖奶 ,满足乳糖不耐症人群的需求。采用北京澳内特乳品有限公司提供的乳糖酶 ,规格 :MaxilactL2 0 0 0NLU/ml,在低温 6℃～ 8℃ 2 6h或在 35℃～ 4 7℃ 4h可水解 85 %以上乳糖。为降低生产成本 ,将乳糖酶加入量减半为 0 .5‰ ,38℃水解 5h ,也可达到同样效果。The lactase biotechnology was applied to produce low lactose milk so as to meet the needs of consumers suffering from lactose intolerance. The β galactosidase Provided by BejJing Honnete Dairy Co. Ltd (Specifications:Maxilact L2000 NLU/ml) is capable of hydrolyzing at least 85% lactose in milk at 6℃～8℃ for 26 hrs or at 35℃～47℃ for 4 hrs. By reducing the amount of β galactosidase from 1‰ and hydrolyzing milk at 38℃ for 5 hrs, We have achieved the same result and greatly cut down the production costs.
