乳糖是天然存在于乳制品中的一种糖,它是婴儿的主要能量来源。正常情况下,人体肠道中的乳糖酶会将乳糖分解为葡萄糖和半乳糖。但是,世界上约有75%的人由于体内乳糖酶活性不足,不能转化所有乳糖,从而出现胃胀气、绞痛、过多排气及腹泻等症状,即乳糖不耐症。因此,越来越多乳品企业认识到无乳糖产品的市场空间,无乳糖产品也如雨后春笋般涌现。由于对乳糖具有“预消化”功能,乳糖酶成为无乳糖产品生产中不可或缺的辅料,而目
Lactose is a sugar found naturally in dairy products and is a major source of energy for infants. Normally, lactase in the human gut breaks down lactose into glucose and galactose. However, about 75% of people in the world are unable to convert all lactose due to insufficient lactase activity in the body, causing symptoms such as flatulence, colic, excessive exhaust and diarrhea, namely lactose intolerance. As a result, more and more dairy companies recognize the market for lactose-free products and lactose-free products have sprung up. Because of its “pre-digestion” function on lactose, lactase becomes an indispensable adjunct to the manufacture of lactose-free products,
