Problems solved by technology

[0003] The purpose of the present invention is to provide a method for extracting rice protein from rice and an extraction device thereof, so as to solve the existing problem of extracting rice protein from rice due to the fact that single-shaft centrifuges are often used for centrifugation during centrifugation. Separation, so that in the centrifugal separation process, the centrifugation process of the centrifuge cannot meet the separation of rice protein, so that in the centrifugal separation process, the separation effect of rice protein is poor, which in turn affects the technical problem of the final precipitation of rice protein

Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] see Figure 1-4 , a method for extracting rice protein from rice, comprising: pretreatment-alkaline extraction-acid extraction-centrifugal separation process, the specific steps of each process are as follows:

[0031]Step 1: Pretreatment, wash the rice to be treated with clean water at 25°C-28°C for 10-15min, dry it with a desiccant for 30-35min at a drying temperature of 80-85°C, and pass the dried rice through a pulverizer Pulverize, the pulverizing speed of the pulverizer is 1200rpm, and the pulverizing time is ...

Abstract

The invention discloses a method for extracting rice protein from rice and an extraction device used in the method. By pretreating the rice first, impurities in the rice are greatly reduced when the rice is subjected protein extraction, so that the purity of protein supernatant is increased during subsequent extraction, the washed and dried rice are easier to be crushed, by adding a NaOH solutioninto an alkaline extraction process, the NaOH solution loosens the dense starch structure of the rice, so that the NaOH solution degrades macromolecular glutelin, the protein dissolution is improved,and the protein extraction efficiency is greatly improved; and by rotatably connecting a drive shaft to the bottom end of a drive motor, a second gear drives a fifth gear to rotate through a first belt to enable one end of a second belt to be movably connected to rotating shafts, so that the two rotating shafts are arranged in a box body, the drive motor can simultaneously drive the two rotating shafts to rotate in the box body when started, and therefore the efficiency of centrifugal extraction in the extraction device is improved.

Description

technical field [0001] The invention relates to the field of a method for extracting rice protein and an extraction device thereof, in particular to a method for extracting rice protein from rice and an extraction device thereof, and belongs to the technical field of the method for extracting rice protein from rice and the application of the extraction device. Background technique [0002] In the past ten years, a lot of basic and applied research on bioactive peptides has been carried out at home and abroad. Under certain conditions, rice protein, corn protein, wheat protein, etc. can be enzymatically hydrolyzed to obtain active peptides that can lower blood pressure and enhance immune functions. This active peptide can be used as an ACE inhibitor. ACE inhibitors can reduce blood pressure by inhibiting the activity of ACE. Rice, etc., as natural materials for advance rice protein, has been studied more and more. When the existing rice protein is extracted from rice, due to ...
