Embodiment Construction

[0010] The present invention utilizes an aqueous enzymatic method to prepare peanut protein in peanut meal. The preparation steps of the present invention are as follows: use non-mildew peanut meal as the main raw material, refine the pulp, and prepare material and water with a material-to-water ratio of 1:10. After being refined by a grinding wheel refiner, adjust the alkaline pH to 7.5-9.5, add 0.15-0.25g / L cellulase, mix well, keep the temperature at 35-55°C, soak for 2h, centrifuge, filter, and take The supernatant is the crude protein solution. At the same time, the peanut dregs in the lower layer are subjected to secondary extraction. The ratio of material to water is 1:5, the pH is adjusted to 7.5-9.5, the temperature is 35-55°C, soaked for 1 hour, and centrifuged centrifuge, filter, take the supernatant, which is the crude protein solution, mix the crude protein solution obtained from the first extraction and the second extraction, carry out acid precipitation, add 3mol...

Abstract

Belonging to the field of food processing, the invention specifically relates to a preparation method of peanut protein. Characterized by environmental protection and high efficiency, the preparation method of the invention comprises the steps of: taking mildew-free peanut meal as a main raw material, and conducting pulp refining, preparing a mixed solution of the material and water in a ratio of 1:10, then carrying out refining with a grinding wheel pulping machine, adjusting the PH to 7.5-9.5, adding cellulase with a concentration of 0.15-0.25g / L, mixing them uniformly, maintaining the temperature at 35-55DEG C, performing immersion for 2h, then implementing centrifugation and filtration, taking the supernatant, i.e. a crude protein solution, and simultaneously conducting secondary extraction to peanut meal slag in the lower layer, maintaining the material and water in a ratio of 1:5, adjusting the PH to 7.5-9.5, controlling the temperature at 35-55 DEG C, and performing immersion for 1h, then implementing centrifugation with a centrifuge as well as filtration, taking the supernatant, i.e. a crude protein solution, and adjusting the PH of a mixed solution of the two crude protein solutions to 4-5, after complete deposition, carrying out filtration and taking the precipitate, thus obtaining a finished product.

Description

Technical field: [0001] The invention belongs to the field of food processing, and more specifically relates to a preparation method of peanut protein. Background technique: [0002] Peanut is one of the six major oil crops in China, and its output ranks first in the world. Peanuts are dry and flat in nature, which can invigorate the spleen and stomach, invigorate the kidneys to remove water, regulate qi and promote milk, and treat various blood diseases. Vitamin K in peanuts has a hemostatic effect, and the hemostatic effect of peanut red coat is 50 times higher than that of peanuts. It has a good hemostatic effect on various bleeding diseases; peanuts contain vitamin E and a certain amount of zinc, which can enhance memory. Anti-aging, delaying the decline of brain function, moisturizing the skin; the vitamin C contained in peanuts has the effect of lowering cholesterol, helping to prevent arteriosclerosis, high blood pressure and coronary heart disease; the trace element...
