Delta-gluconolactone Powder Usage and Synthesis.

Gluconolactone is a non-toxic edible substance used in the production of tofu and as a protein coagulant in dairy products. Tofu made with gluconolactone is more tender, flavorful and nutritious than traditional tofu and is not harmful to the body. Gluconolactone is also used as an acidity regulator in thin cream.

Uses of Delta-gluconolactone.

Used as raw material for tofu coagulant, flavoring agent, pH reducing agent and bulking agent. In Japan, for tofu coagulant accounted for 50% -70% of the total amount of Japan, with the product made of tofu, pure texture, tender and delicious, and can extend the preservation time. China's food additives use of health standards (GB2760-86) provides for the maximum use of 3.0g/kg.

Gluconolactone is used in milk industry to prevent the generation of milk stone, brewing industry as a preventive agent for beer stone, added to toothpaste to help remove tartar, but also used in animal meat, metal surface treatment agents.

It is widely used as souring agent, fermentation agent, protein coagulant, PH lowering agent, color tone keeping agent, food preservative and so on. The made lactone tofu is tender in texture, no odor, no protein loss, and has antiseptic property. It can also be used in cosmetics, textile, paper making, medicine and so on.

Gluconolactone can be used as stabilizer and coagulant, can be used for soy products (tofu and soybean flower), sausage (sausage), minced fish products and grape juice, the maximum amount of 3.0g/kg; as a preservative, can be used for the preservation of fish and shrimp, the maximum amount of 0.1g/kg, the residue of 0.01mg/kg; also as a bulking agent for the preparation of composite baking powder, the amount of use in accordance with the production needs.

Pharmacological effect of Delta-gluconolactone.

Product Method of Bulk Delta-gluconolactone Powder.

The gluconic acid solution was concentrated to 78%-85% at 52-54°C, cooled to 47-48°C, the gluconolactone crystal seed was added and continued to be concentrated, and the first batch of lactone crystals was isolated when the crystal seed grew up. The mother liquor continues to evaporate and concentrate in the same way. The crystals were washed, dried to the finished product, the total yield of 75% to 78%. The advantage of this method is not to use organic solvents, but the viscosity of the concentrate is high, crystallization and separation operation is difficult.

Azeotropic dehydration crystallization method to the gluconic acid solution to add C3 ~ C4 alkanol, at 50 ℃ and 16kPa azeotropic dehydration. Then put the crystal seed into the concentrated liquid, crystallize at a reduced temperature, and then separated, washed and dried to get the finished product. The advantage of this method is that the system viscosity is low, the separation operation is easy, and the one-way yield can be more than 91%.
