Embodiment Construction

[0014] A rice protein ionization method, comprising the following steps:

[0015] (1) Pretreatment: use 3-8‰ (example 3‰, 5‰, 8‰) alkaline protease to enzymolyze the rice milk water with concentration of 17~18Be′ under the condition of pH8.9~9.0, enzymolysis The temperature is 40-45°C, and the enzymatic hydrolysis time is 3-6 hours;

[0016] (2) Put the pretreated slurry water at a rate of 10m with pump 1 3 / hour flow, 4kg / f cm 2 Pressure, after heat treatment by the plate heat exchanger 2, it enters the ionization device for ionization treatment. During the ionization treatment, the slurry water concentration is adjusted at 7-8Be', the pH is 8.9-9.0, the temperature is 25-30°C, and the ionization time is 30-60 minutes , the ionization adopts three-level ionization, and the three-level ionization devices are connected in series in sequence. The slurry water enters from the first-level ionization device 3, passes through the second-level ionization device 4, and flows out f...

Abstract

The rice protein ionizing separation process includes pre-treatment, ionizing treatment and other steps. The technological process is simple and easy in operation, and can separate protein and starch from rice slurry in high efficiency.

Description

Technical field: [0001] The invention relates to a method for extracting starch and protein from rice. Background technique: [0002] Rice is rich in protein and starch, and there is no high-efficiency method for separating protein and starch from rice in the prior art. Invention content: [0003] The purpose of the present invention is to provide a rice protein ionization method that can conveniently separate and obtain protein and starch from rice milk. [0004] Technical solution of the present invention is: [0005] A rice protein ionization method is characterized in that: comprising the following steps: [0006] (1) Pretreatment: use 3-8‰ alkaline protease to enzymolyze rice milk water with a concentration of 17-18Be' at pH 8.9-9.0, enzymolysis temperature 40-45°C, enzymolysis time 3- 6 hours; [0007] (2) Enter the pretreated pulp water into the ionization device for ionization treatment. During the ionization treatment, the concentration of the pulp water is ad...
