Method for splitting nutrient substances of soybean milk powder
Technical Field
The invention relates to the technical field of nutrient substance resolution, in particular to a method for resolving nutrient substances of soybean milk powder.
Background
The milk powder is prepared from milk of cow by sterilizing, defatting, dewatering, and drying. It may also be a product produced using the milk of other animals such as goats. The milk powder can be prepared into modified milk powder, common milk powder, skimmed milk powder and the like according to different production processes and different additive materials, and can be infant milk powder, children milk powder, adult milk powder, milk powder for pregnant women, old people milk powder, special animal milk powder such as cats, dogs and the like according to different using objects. Milk powder is also called milk powder as another name. The milk powder is a food which is prepared by using fresh milk as a raw material, removing almost all water in the milk by a freezing or heating method, drying and adding a proper amount of white granulated sugar. The milk powder is easy to be mixed, convenient to carry and rich in nutrition. The instant milk powder has larger and more loose particles than common milk powder, and can be dissolved quickly by using warm water. Substitutes in animal proteins, also known as surrogate proteins, are of great interest. Thus, many plant milks have emerged. Vegetable milks produced from vegetable ingredients can be used as a substitute for animal derived milk. They overcome and avoid CMPA. The vegetable milk is free of casein, lactose and cholesterol, is rich in vitamins and minerals, and is also rich in essential fatty acids with low content of saturated fatty acids. Some plant milks also contain higher levels of dietary fiber.
The prior art is not mature in the resolution of the nutrient substances of the soybean milk powder and has not good separation effect on protein, grease and carbohydrate, so that further improvement treatment is still needed.
