Problems solved by technology

The most important thing is to make soybean milk (soybean milk powder) and peanut milk (peanut milk powder) from soybeans and peanuts. Compared with milk, the former does not contain animal cholesterol and is extremely beneficial to human health. Difficult to dissolve, sometimes agglomerated and precipitated

Embodiment

[0014] (1) Cleaning and removing impurities: select raw materials with pure color and full particles, remove various impurities, such as soil, stones, metal, glass, dust, etc., and use low-temperature drying process to quickly dry the dried raw materials After cooling to room temperature, use a soybean peeling machine and a peanut peeling machine to remove all the outer skins;

[0015] (2) Coarse grinding and fine grinding: mix peanuts and soybeans with water in proportion, and evenly enter the grinder to grind them to a fineness of 15urn;

[0016] (3) Separation: blend the ground slurry into an alkaline solution, make the solution in a suspension state under the action of a mixer, and then use a centrifuge to separate the grease and solid residue;

[0017] (4) Homogenization: Homogenization is the tempering treatment of further mixing and micronizing part of the oil and protein particles in the protein solution;

[0018] (5) Sterilization: After the processing of the previou...

Abstract

The present invention relates to protein powder, specifically to a preparation method for peanut and soybean instant protein powder, and belongs to the technical field of food processing. According to the method, raw materials and water are mixed according to a certain ratio, wherein the raw materials comprise peanuts and soybeans; the soybeans and the peanuts are crushed and grinded under effects of mechanical friction force, shearing force and calendering force in the context of small temperature change so as to damage cell walls, such that proteins and fats are exposed, the proteins are dispersed in the water with the hydrophilicity of the protein and the hydrophobic interaction of the fat, meanwhile, the fats are squeezed from the broken cells; under the stirring effect, the other part of the unemulsified fats directly float on the liquid surface; a centrifugal separation method is adopted to separate emulsifiable concentrate and crude fiber in the suspension to obtain the protein solution with no any change; then the treatment of spray drying is performed to obtain the instant protein milk powder with good quality.

Description

technical field [0001] The invention relates to protein powder, in particular to a preparation method of peanut and soybean instant protein powder, which belongs to the technical field of food processing. Background technique [0002] Soybeans and peanuts are the main economic crops of agricultural products in my country and the main raw materials of the food processing industry. At the same time, soybeans and peanuts are of great nutritional value, strong flavor, rich in various nutrients necessary for the human body, and also contain high of protein. Among the contained protein, the ratio is very reasonable, and it is easily absorbed by the human body, and the digestion and absorption rate is as high as 90%. The most important thing is to make soybean milk (soybean milk powder) and peanut milk (peanut milk powder) from soybeans and peanuts. Compared with milk, the former does not contain animal cholesterol and is extremely beneficial to human health. Difficult to dissolve...
