Problems solved by technology

The main problems in the existing technology are: "Maillard" reaction, that is, amino compounds such as protein, amino acid, etc., interact with sugar to produce browning, resulting in darker milk powder; Under the joint action of air, temperature and other factors, the fat will be degenerated, the fat will be hydrolyzed into glycerol and fatty acid, and the fatty acid will be oxidized to produce aldehydes and ketones, resulting in an unpleasant smell; mildew caused by incomplete sterilization during the processing of milk powder; vitamins and Oxidation-reduction reactions between minerals, etc.
[0005] At present, although some oil substances have been embeded to change their dispersion in solid materials or solubility in water-soluble substances, the "Maillard reaction" and nutrients in formula milk powder have not yet been resolved. Redox reactions of vitamins and minerals in

Abstract

The present invention relates to a wet preparation process of infant formula milk powder, wherein raw materials comprise vegetable oil, fresh milk, desalted whey powder, lactose, whey protein powder, oligosaccharide, compound vitamins, compound minerals, other nutrients, a microcapsule wall material and the like. The preparation method comprises: embedding vitamins, minerals, vegetable oil, oils in other nutrients by using a microcapsule technology; uniformly mixing the embedded vitamin powder, the embedded mineral powder, the embedded oil nutrient powder and other nutrients with the amount of less than 5% to obtain a mixture; mixing fresh milk, whey powder, lactose, whey protein and oligosaccharide, carrying out homogenization by using a high pressure homogenization machine, carrying out concentration and spray drying to obtain powdery base powder, and uniformly mixing the mixture and the base powder; and carrying out nitrogen filling quantitative package. According to the present invention, the part of the substances with characteristics of easy reaction generation and instability is embedded through the microcapsule technology, and the mixing and packaging preparation process is performed under a certain condition so as to reduce or prevent adverse reactions among the substances; and the prepared infant formula milk powder has advantages of good stability, good uniformity, good taste and assurance of nutritional activities of various components.

Description

technical field [0001] The invention relates to the technical field of dairy product processing, in particular to a wet preparation process of formula milk powder for infants and young children. Background technique [0002] Infant formula milk powder is to meet the nutritional needs of infants and young children. Various nutrients are added to the milk powder to achieve the effect close to breast milk. Compared with ordinary milk powder, infant milk powder removes part of casein and increases whey protein; removes most of saturated fatty acids, adds vegetable oil, and increases unsaturated fatty acid DHA (docosahexaenoic acid, Commonly known as brain gold) and AA (arachidonic acid); lactose is also added to the formula milk powder, and the carbohydrate content is close to human milk; in addition, vitamins, minerals, trace elements, certain amino acids or other nutrients are added to make it closer to human milk. [0003] At present, there are two preparation techniques fo...
