[0026] Example 1:
[0027] A method for extracting peanut polypeptides from peanut meal, comprising the following steps:
[0028] 1. After shelling the non-deteriorated peanuts, use the physical pressing method for several times to form a cake-shaped standby peanut meal with a thickness of 3cm and a diameter of 35cm.
[0029] 2. After placing the peanut meal in a cool place for 72 hours by natural air-drying, it is placed in a dryer for drying, the temperature of the dryer is adjusted at 80°C, and the drying time is 4 hours.
[0030] 3. Move the dried peanut meal to a pulverizer and pulverize it into small particles with a diameter of 1~2mm to obtain peanut meal particles.
[0031] 4. The peanut meal particles are moved to a neutralization pot, and NaOH solution is added for degreasing treatment. The solid-liquid mass ratio of peanut meal particles and NaOH solution is 1:5, and an alkaline degreasing suspension is formed after thorough stirring. The pH value of the added Na...
