Low-lactose nutrition fortification milk for children and its production method

Abstract

The invention relates to a low-lactose nutrition fortification milk for children and its production method. The low-lactose nutrition fortification milk is prepared from the following raw materials: 100 kg of raw mil, 50 to 200 g of lactase with an activity of no less than 2000 NLU / g, 100 to 500 g of an emulsifier, 30 to 50 g of taurine, 60 to 100 mg of vitamin A, 1 to 4 mg of vitamin D, 1 to 2 g of ferric pyrophosphate in terms of the Fe element, 0.5 to 1 g of zinc citrate in terms of the Zn element and 20 to 44 g of fish oil. The production method comprises the steps of enzyme hydrolysis of lactose in the raw milk for preparation of low lactose raw material milk, mixing of nutrients and the emulsifier for preparation of material liquid to be sterilized and pasteurization, filling and examination of a product. According to the invention, lactose in the raw milk is degraded into micro-molecular galactose and glucose which are favorable for digestion and absorption, which enables problems caused by lactose intolerance to be avoided; meanwhile, the nutrient elements vitamins, minerals, fish oil (containing DHA and ARA) promoting development of intelligence and the like are added into the low lactose raw milk obtained after lactose degradation; therefore, a foodstuff suitable for growth and development of children is produced. A hydrolysis conversion rate of lactose is 97 to 99% in the invention.

Description

technical field [0001] The invention belongs to the field of dairy products. In particular, it relates to a low-lactose nutritionally fortified milk for children and a production method thereof. Background technique [0002] Lactose is a special sugar in animal milk. Its content in milk is about 4.6-4.8%. It is a disaccharide. Milk must be hydrolyzed by lactase in the small intestine into monosaccharides, namely glucose and half lactose to be absorbed. People with lactase deficiency, after eating milk or dairy products containing lactose, lactose cannot be completely digested and absorbed and stays in the intestinal cavity, which increases the osmotic pressure and volume in the intestine, accelerates intestinal emptying, and makes lactose quickly It is discharged into the large intestine and absorbs water in the large intestine, and is fermented by bacteria to produce gas. In mild cases, the symptoms are not obvious, but in severe cases, symptoms such as abdominal distensi...

Problems solved by technology

[0004] In the prior art, there is no low-lactose nutrition-fortified milk suitable for children's physical and mental development, which causes lactose-deficient children to be unable to drink milk. There is no report of children's low-lactose nutrition-fortified liquid milk.
