Abstract

The invention relates to the technical field of biology, in particular to instant milk powder contributing to digestion and absorption and a preparation process thereof. According to the preparation process, milk protein concentration is firstly hydrolyzed into peptide, thereby reducing the viscosity of feed liquid, and facilitating working procedures such as pipeline transportation and later-period desugarization and enzyme deactivation; meanwhile, digestion and absorption are easier, and sensitization is reduced. A product provided by the invention contains OPO with the chemical name of 1,3-dioleoyl-2-palmitoyl triglyceride, so that the product is more approximate to breast milk, and has remarkable effects of reducing constipation and defecation difficulty of babies, reducing loss of nutritional ingredients and promoting skeletal development of the babies. Meanwhile, the invention relates to the production process of the milk powder, and solves the problem of difficult brewing of milk powder due to the existence of fine powder; the fine powder can not only be recycled, but also be recycled for granulation.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to an instant milk powder which is helpful for digestion and absorption and a preparation process thereof. Background technique [0002] At present, along with economic development, the sickness rate of cow's milk allergy increases substantially, has caused widespread concern both at home and abroad, and has become one of research hotspots. Studies have shown that the macromolecular protein in cow's milk is the main cause of allergy, and wherein casein, beta-lactoglobulin and a-lactalbumin are the main allergens. The results can lead to symptoms such as vomiting, diarrhea, reddened skin, and asthma. When the immune response is too strong, untimely rescue may even lead to death. About 2-6% of infants and young children will be allergic to cow's milk protein. [0003] ] Furthermore, with economic development, the incidence of lactose intolerance caused by lactose in dairy products has ...
