Food business network newsletter in glutathione (GSH) is formed by the condensation of glutamic acid, cysteine and glycine by peptide bonds tripeptide compound, is widely used active peptide having a molecular weight of 307.33, The melting point is 189 ~ 193 ° C, the appearance of colorless transparent slender granular crystal. GSH is widely found in baker's yeast, wheat germ, animal liver, chicken blood, pig blood, tomato, pineapple, and cucumber. Among them, wheat germ and animal liver are the highest, and the content is as high as 100-1000 mg/100 g.
Glutathione is soluble in water, dilute alcohol, liquid ammonia, dimethylformamide, and insoluble in ethanol, ether, and acetone. The solid is stable in its properties, and its aqueous solution is easily oxidized to oxidized glutathione (GSSH) in the air.
Glutathione has anti-oxidation, scavenging free radicals, detoxification, enhancing immunity, delaying aging, anti-cancer, anti-radiation hazard and other functions. It is an important functional factor and is widely used in the food industry and pharmaceutical industry.
Antioxidants
GSH contains active sulfhydryl-SH, which can reduce H2O2 produced by human cell metabolism to H2O, and remove free radicals from the human body. Free radicals can damage cell membranes, promote body aging, and induce tumor or arteriosclerosis. GSH has anti-peroxidation effect on human cells, and can also improve the skin's antioxidant capacity and make the skin shine.
Glutathione has the function of eliminating the formation of oxidized lipids, and has anti-oxidation effect, and can prevent the appearance of taste nucleotides (inosinic acid, guanylic acid) foods (fish cakes, sausages, soy sauce, etc.). The taste nucleotides decompose and lose their fresh taste. In addition, it enhances the flavor of the food and greatly extends the shelf life of the food.
The anti-browning agent glutathione has a function of preventing pigmentation, preventing skin aging and pigmentation, and reducing the formation of melanin. Adding glutathione to canned fruit can prevent browning of fruits; adding to dairy products can effectively prevent enzyme and non-enzymatic browning.
The glutathione additive of the noodle food quality improving agent can shorten the kneading time of the dough, and even after the kneading is finished, the preservation for a certain period of time does not affect the fermentation after thawing, thereby producing a good quality bread. Glutathione also has the effect of strengthening amino acid nutrition.
Enhancement of meat flavor and other enhancers glutathione and de-salt, sodium L-glutamate, xylose in the presence of heat will produce very good beef flavor; and taste nucleotides such as inosinic acid, guanylic acid and When mixed with sodium glutamate, it produces a strong meat flavor. It can be used as a flavoring agent and flavoring agent in various processed foods. Glutathione is also added to meat products, cheese and other foods to enhance the flavor effect.
Antidote
GSH has a broad-spectrum detoxification effect, and can be combined with toxic compounds entering the body such as acrylonitrile, fluoride, carbon monoxide, heavy metal ions or carcinogens, and promote its excretion, which can be used for the treatment of poisoning of the above substances.
Recent studies on anti-allergic agents have shown that GSH can treat allergies caused by the imbalance of acetylcholine and cholinesterase in humans and has anti-allergic effects.
Hepatic protective agent
GSH has the function of protecting the liver and inhibiting the formation of fatty liver. It can be used not only as a liver protecting agent, but also as a feed additive, and has a liver protecting effect on fish and cattle. In the culture, due to over-range stocking and unclean feed, liver dysfunction occurs in fish and dairy cows. Adding glutathione can improve liver function.
Protect white blood cells
GSH has a preventive effect on leukopenia caused by radiation, radioactive drugs or anti-tumor drugs, and can be used for adjuvant treatment of tumor radiotherapy and chemotherapy.
GSH's broad-spectrum physiological function can be widely used in foods, especially in anti-aging, immune-enhancing, anti-tumor function foods as base materials, fortified nutrition, additives, etc., and has broad application prospects.
Method for producing glutathione
1. Extraction from wheat germ According to Japanese patent reports, wheat germ has a high glutathione content and can be extracted. Its production process is:
Wheat Germ→Degreasing→Refining→Filtering→Organic Solvent→Phase Separation→Desolvation→Clarification of Protein Removal→Concentration→Decolorization→Spray Drying→Finished Product.
The organic solvent may be an organic acid solution, an enol, an ester, and a mixture of these. The extraction of high-purity glutathione also requires refining, and techniques such as chromatographic separation or membrane separation can be employed.
2. The use of cyanobacteria to synthesize glutathione Japan Shimane University research and development using cyanobacteria in hot springs to make glutathione. Cyanobacteria produce GSH in cells by photosynthetic pathway, which is a photofermentation method. Cyanobacteria cells are produced in vivo after light irradiation
The ADP-ATP-ADP energy cycle generates energy that causes glutathione synthetase in the cell to produce glutathione and release it to the outside of the cell to obtain a product. Japan also adopts a method of cultivating green algae and extracting it from green algae to obtain GSH.
3. Extraction from glutathione-containing yeast is carried out by fermenting high glutathione yeast, extracting and refining the product.
