Mung bean pea edible separation protein and producing method thereof

Abstract

The invention relates to a kind of isolating edible protein in the mung bean and pea and the producing method thereof, which belongs to the field of the edible protein producing method technology. It is characterized in that, the steps are as follows: a. alkali dissolving: adding alkali solution into the waste mud after starch processing of the mung bean and pea, adjusting pH to 9.0-11.0; b. impurity isolation: separating by separator, discharging parts of fiber and residues of the protein solution; c. acid precipitation: adding hydrochloric acid solution into acid tank for adjusting pH to 4.5-5.5; d. protein concentration: secondary separation, adding water for adjusting the density of the protein solution to 8-15%; e. neutralizing: adding alkali solution for adjusting pH up to 7.0; f. sterilizing, removing soy smell: high temperature sterilizing, flashing and then degassing and removing soy smell; g. homogenizing: homogenizing in homogenizer; h. spray drying: spray drying for acquiring edible isolating protein. The invention uses the seriflux produced by starch process as the raw materials to produce edible protein, the product has good appearance, good quality, and has solubility, emulsifying property, water absorbing and oil protecting ability, foamability and other good characteristics, and is environment protected.

Description

1. Technical field [0001] The invention relates to a method for producing edible protein isolate from mung bean and pea, and belongs to the technical field of edible protein production methods. 2. Background technology [0002] Mung beans are cool in nature, sweet in taste, and rich in vitamins A, B, and C. They have the effects of relieving heat and thirst, lowering blood pressure, diuresis, lowering qi, and detoxifying. It is also one of the important raw materials in the food industry and brewing industry, and it is also an important medicinal material. Mung bean consumption is mainly concentrated in three aspects: edible, deep processing and export. [0003] Peas are rich in various nutrients needed by the human body, especially high-quality protein, which can improve the body's disease resistance and recovery capabilities; peas are rich in carotene, which can prevent the synthesis of human carcinogens after eating, thereby reducing cancer. The formation of cells can r...

Problems solved by technology

[0008] Domestic manufacturers of vermicelli recover protein from mung bean and pea starch slurry. The method is too simple, that is, the slurry is extracted through natural precipitation, thermal flocculation, concentration, cooking, and drying. A large amount of heat energy is consumed by heating, and the protein is completely Denaturation, solubility, foaming, whipping, emulsification, etc. are completely lost, and can only be used as feed, while the extraction of protein has caused a certain degree of pollution to the environment
