Embodiment Construction

[0014] A method for extracting rice germ protein, comprising the steps of:

[0015] (1) Weigh the degreased sample, add water to dissolve it, preheat it in a water bath, put it into a constant temperature magnetic stirrer and vibrate to dissolve the protein in the sample solution, centrifuge at 4000r / min for 20 minutes, and collect the supernatant, namely for albumin;

[0016] (2) Take the above-mentioned residue extracted by water, add 6% sodium chloride solution, after fully dissolving, collect the supernatant by the same method, which is globulin;

[0017] (3) Add the residue to 70% ethanol solution, dissolve, collect the supernatant, which is the alcohol-soluble protein:

[0018] (4) Add 0.4% sodium hydroxide to the remaining precipitate, fully dissolve, and prepare gluten in the same way.

[0019] The amount of water added in the present invention is 75mL, the extraction temperature is 40°C, and the extraction rate is 51.01% for 30min; the sodium chloride solution is 62...

Abstract

The invention discloses a method for extracting rice germ protein. The method comprises the following steps: (1) weighing a degreased sample, feeding water and dissolving the sample; preheating the sample in a water bath kettle, putting into a constant temperature magnetic stirrer, vibrating to enable protein to be dissolved in the sample solution, centrifuging for 20 minutes at the speed of 4000 revolutions/minute, and collecting supernatant liquor which is albumin; (2) taking the residue extracted by water, feeding a 6% sodium chloride solution, fully dissolving, and collecting supernatant liquor according to the same method, wherein the supernatant liquor is globulin; (3) feeding the residue into a 70% ethanol solution, dissolving, and collecting supernatant liquor which is alcohol soluble protein; (4) feeding 0.4% sodium hydroxide into the rest precipitate, fully dissolving, and preparing glutelin by the same method. The method is simple and clear in steps, reasonable in working procedures and convenient to operate; after the method for extracting the rice germ protein is used, the product is high in quality, efficient, high in content of nutritional ingredients, free from an additive, healthy and harmless, thus being suitable for various patients with hypoproteinia.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction method of rice germ protein. Background technique [0002] Protein is the main source of nitrogen for the human body. It can not only provide part of the energy consumed, but also be used to synthesize new tissues. Protein accounts for about 17% of body weight in adults, and 3% of protein participates in metabolic renewal every day. When there is insufficient protein in the body, people's basic life activities will be affected, which can lead to growth retardation, underweight, and mental retardation in children and adolescents; fatigue, weight loss, anemia, decreased plasma albumin, and even edema in adults. Although traditional dietary protein can effectively prevent or improve these symptoms, it has a single nutritional component and only focuses on protein content, which is very harmful to human health. In view of the above defects, it is necessary to design a method fo...
