Problems solved by technology

[0003] Bean sprouts is a product obtained by germinating soybeans. Because of its delicious taste and low price, it is deeply loved by consumers. Therefore, if the selenium element can be combined with bean sprouts, the selenium deficiency can be effectively solved to a certain extent. Based on this One point, the application number is 201910249051.0 which discloses a new production method of selenium-enriched bean sprouts; the application number is 201810023459.1 which also discloses a production method of selenium-enriched bean sprouts; This process is complicated to operate, the process is long, and there are many links that affect the effect of selenium enrichment, which is not conducive to standardized production. Moreover, the use of spraying sodium selenite solution to germinate selenium enrichment will cause sodium selenite to flow into the environment with water, causing environmental damage Pollution

preparation example Construction

[0034] (1) Preparation of polypeptides: extract proteins from animals and plants by alkali-dissolving and acid-precipitating methods, or directly crush and refine animals and plants, then add protease to the obtained proteins or slurry for enzymatic hydrolysis, inactivate enzymes, and make polypeptide solutions The specific operation is: first ultrafinely pulverize the animals and plants, then mix the pulverized animals and plants with water at a mass volume ratio of 1:15-40, adjust the pH to 8.5-10.5 with 0.5-1.5 wt% alkali solution, and ultrasonically After extraction for 20-45min, extract in a water bath at 60-90°C for 45-150min, filter, adjust the pH of the filtrate to 2.5-4.5 with hydrochloric acid for protein precipitation, centrifuge at 4000-6000r / min for 5-10min to obtain the precipitated protein, wash with water until neutral and then again centrifuge, and freeze-dry the obtained precipitate to obtain the protein; the alkaline solution is NaOH solution or KOH solution....

Abstract

The invention discloses a production method of novel organic selenium-enriched bean sprouts. The production method comprises the following steps of disinfection, specifically, removing impurities and imperfect grains from soybeans, immersing the soybeans in a sodium hypochlorite solution with the mass percent concentration of 0.5-1.0% for disinfection for 5-30 minutes, and then washing the soybeans with clear water, preparing a nutrient solution, specifically, dissolving a selenium-containing polypeptide solution into water, and preparing an organic selenium solution with the selenium content of 1-5mg / L according to a proportion for later use, soaking, specifically, soaking the disinfected soybeans in the nutrient solution, wherein the ratio of the volume of the nutrient solution to the mass of the soybeans is (2.5-5): 1, and culturing, specifically, placing the soybeans in a seedling culture device, and culturing under a constant-temperature dark condition. The organic biological peptide-selenium chelate prepared by chelating polypeptide and inorganic selenium is used as a selenium source, so that the organic biological peptide-selenium chelate is absorbed by the soybeans in the growth process and is safe and non-toxic, and meanwhile, the polypeptide can effectively supplement amino acid and protein and enhance the nutrition of the bean sprouts.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for producing novel organic selenium-enriched bean sprouts. Background technique [0002] Selenium is an essential trace element for humans and animals. It is a constituent element or active center of various enzymes in the body, especially an important component of glutathione peroxidase, which can prevent peroxides and free radicals in organisms. formation, thereby preventing its damage to the body's membrane system and cell structure. Adequate intake of selenium can prevent diseases, delay aging, enhance the body's immunity, and resist the damage caused by various heavy metal elements to the body. Selenium deficiency in the human body can cause various diseases such as Keshan disease, Kaschin-Beck disease, liver necrosis, growth retardation, reproductive disorders and AIDS infection. However, the selenium intake from food by residents in 70% of my country us...
