Wheat germ, I think a lot of people never eat, and do not know what nutritional value in it. Wheat is one of Chinese main source of food, which is mainly composed of endosperm, germ, bran. Wheat germ is the essence of the wheat grain, embryos of life, although it accounts for only 1.5% to 2% in the wheat grain, it contains high concentrations of life-sustaining movement of nutrients, to be known as “human treasure trove of natural nutrients”, “anti-aging food”, “beauty anti-fatigue movement food” and “nutrition diet food”.
According to cosmetic raw material suppliers, the full price of vitamin E in wheat germ (have α,β,γ,δ four types) can not be ignored in skin care beauty, synergies with vitamin C can reduce skin infection, moisturize the skin's collagen fibers and elastic fibers, and to improve the maintenance of skin flexibility, promote blood circulation in the skin. Make the skin look more delicate and elastic. Glutathione in wheat germ can catalytic organic peroxides restore, its antioxidant capacity was 500 times stronger than vitamin E, is an anti-aging functional factors. Wheat lectin in wheat germ contains a variety of biological effects such as anti-microbial and anti-mutagenic reaction and fat cells, insulin-like role, can stimulate glucose oxidase to lower blood sugar levels, can induce macrophage cell lysis of tumor cells. Vitamin E release heavy metals (such as cadmium, lead) toxicity and inhibition of the nitrite reaction function, so that in preventing and treating a variety of tumors have certain effects.
Use wheat germ as the main raw materials, plus water extract pretreated wheat germ, then separated by centrifugation, concentrated, spray drying, preparation of wheat germ protein extraction and separation process parameters to optimize and improve the production technology of wheat germ proteinroute, the results showed that the use of alkaline protease and the role of flavor protease, can enhance the dissolution rate of defatted wheat germ protein to more than 80%, the rich variety of the amino acids required by the body, the content and proportion of the resulting proteins are close to the WHO recommended values, and the resulting product has good features, including solubility, foaming, emulsification and water holding capacity, have a good prospect in the food industry.
Enzymatic hydrolysis of wheat germ protein extracts prepared hydrolyzate and study on the physicochemical properties, based on this further separation and purification of wheat germ glycoprotein, and its physicochemical properties and structure were analyzed, the results showed that the basic structure of the wheat germ protein containing higher levels of sugar, sugar and protein to peptide bond of the O-type sugar connection, on the oligosaccharide chains of α-D-mannose pyranosyl residues, C-2, C-3bit or no occurrence of the C-4 position hydroxyl substituted, hexuronic acid and 6 - position deoxysugars methyl exist.
Wheat germ water-soluble extract containing a lot of glutathione, glutathione manufacturer optimized the glutathione separation and preparation process, and the results show that, with a pore size of 0.6μm and 0.005μm inorganic ceramic membrane tubes twice separationcan retain more than 90% protein, and provides convenience to enrich glutathione. Use the adsorption of large pore size of resin, glutathione concentration in the sample can be further improved to 0.80mg/ml. And set up reliable and accurate detection method of glutathione.
