Glucono-delta-lactone Usage and Function.

Gluconolactone is used as food additives as acidifier, used in fruit juice, beverage and jelly; used as coagulant, gluconolactone is a food coagulant permitted to be used by GB2760-1996, used in soy protein, cow's milk protein, as a coagulant for tofu, add 0.25% to 0.3% in soya bean milk, compared to calcium sulphate, due to the better water solubility of the product, it can be dispersed evenly in soya bean milk and made into delicate tofu. Compared with calcium sulphate, due to better water solubility, it can be dispersed evenly in soya milk, and the tofu made is delicate, often used in combination with calcium sulphate; used as a bulking agent, compared with other acids, it is not easy to react at low temperatures, and only becomes gluconic acid after heating, and then reacts with sodium bicarbonate to produce carbon dioxide bubbles, foaming uniformly and finely, and can be used as a bulking agent for biscuits, bread and so on, especially suitable for cakes; used as a chelating agent to regulate the pH value of milk products and prevent the generation of It can be used as chelating agent to regulate the pH value of milk products and prevent the production of milk stone and beer stone; it can also be used as toothpaste additives to help remove tartar, which is because this product can react with tartar; it can also be used as photographic developer, stabiliser of vitamins and irritation reliever in medicine and cosmetic; textile gluing additives; additives for detergents; bottle washing agent; cleaning agents for metal surfaces before plating, and so on.

Uses of Glucono-delta-lactone.

Used as raw material for tofu coagulant, flavouring 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 tasty, and can extend the preservation time. China's food additives use of health standards (GB2760-86) provides that the maximum use of 3.0g / kg. Gluconolactone is used in the milk industry to prevent the generation of milk stone, brewing industry for the prevention of brewer's stone agent, added to toothpaste to help remove tartar, in addition to animal meat, metal surface treatment agents, and so on.

Gluconolactone can be used as stabiliser and coagulant, can be used in soya bean products (tofu and soya bean flower), sausage (meat sausage), minced fish products and grape juice, the maximum amount of 3.0g/kg; as a preservative, can be used for fish and shrimp preservation, 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.

Widely used as acidifier, fermentation agent, protein coagulant, PH reducing agent, colour tone keeping agent, food preservative and so on. The texture of lactone tofu is tender, no odour, no protein loss, and it has antiseptic property. It can also be used in cosmetics, textile, paper making, medicine and so on.

Preparation of Glucono-delta-lactone.

Product Method of Bulk Glucono-delta-lactone Powder.

The raw material calcium gluconate is first hydrolysed with sulphuric acid to obtain gluconic acid solution. After filtration to remove calcium sulfate precipitation, the solution is then refined with barium hydroxide and oxalic acid, and settled and separated to remove SO42- and Ca2+ from the solution.

The gluconic acid solution is then further purified by ion exchange resin. Concentrate the solution to 80%-85% concentration, add gluconic acid-δ-lactone crystal seed, continue to concentrate and crystallise, centrifugal separation, washing and drying to get the finished product.
