Glucono Delta Lactone, also known as glucolactone, referred to as GDL or lactone, is produced by the oxidation of glucose to gluconic acid or its salts, after purification, desalination, decolorization and concentration. It is used as coagulant, stabilizer, acidizing agent, preservative and preservative in food industry, and it is a multifunctional food additive. As a preservative, it has antiseptic effect on mould and general bacteria. It can be used for antiseptic and fresh-keeping of fish, meat, poultry, shrimp, etc. to make the appearance of the product shiny, without browning, and keep the elasticity of the meat quality. As a loosening agent, the product is mixed with sodium bicarbonate to make fermentation powder. When heated, gluconic acid reacts with sodium bicarbonate to produce carbon dioxide, which has good swelling effect and no peculiar smell. Especially suitable for pastry, fried food, etc. S Adenosyl methionine is a kind of physiological active molecule existing in all tissues and body fluids of human body. It is involved in important biochemical reactions in vivo as a precursor of methyl donor (transmethylation) and physiological sulfur compounds (such as cysteine, taurine, glutathione and coenzyme A). In the liver, the fluidity of liver cell membrane is regulated by methylation of plasma membrane phospholipid, and the synthesis of sulfurized products can be promoted by trans sulfur reaction. As long as the bioavailability of adenosylmethionine in the liver is within the normal range, these reactions will help prevent intrahepatic cholestasis. Quillaja Saponin is a type of glycoside compound extracted from soapbark(quillaja bark). It's a kind of brown yellow powder with the main ingredients-saponin. (saponin) . The test method is UV . Its contentcan be up to 95%.It can be soluble in water, insoluble in benzene, chloroform and ether. It is a natural surfactant with good performance. It can be widely used in light industry, chemical industry, pesticides, feed, breeding, textiles , Oil extraction, mining, building materials and highway construction, etc., to make emulsifiers, detergents, pesticide additives, feed additives, crab and shrimp breeding protective agents, textile additives, oil field foaming agents, mining flotation agents and aerated concrete Foam stabilizer and concrete admixture-antifreeze, etc.
