Glucona Delta Lactone(GDL)
SINOBIO
2932209090
Glucona Delta Lactone (GDL), or Glucono-Delta-Lactone, is a white crystalline powder produced by the fermentation of glucose, which is easily soluble in water, and has multiple functions such as slow-release acidification, protein coagulation, and preservation of freshness, and is widely used in the food industry. The following is the detailed introduction of GDL:
Chemical formula: C₆H₁₀O₆
CAS No.: 90-80-2
E code: E575
Alias: Gluconolactone, δ-gluconolactone, GDL
Physical Properties: white crystalline particles or crystalline powder, easily soluble in water, insoluble in ether. Almost odorless, with a slight sweet taste.
1. Slow-release acidifier: GDL dissolves quickly when added to an aqueous solution and slowly hydrolyzes to gluconic acid, resulting in the same mild acidifying effect as lactic acid bacteria. This property makes it an ideal slow-release acidifier that ensures a gradual and continuous reduction of the pH level to equilibrium.
2. Protein coagulant:GDL is an effective coagulant for milk and soy proteins. In tofu production, using GDL instead of brine or gypsum can produce white and tender tofu with no bitter or astringent flavor, no protein loss, and a high yield.
3. Preservative: GDL has antiseptic effect on mold and general bacteria, it can be used for fish, meat, poultry, shrimp, etc. It can make the products look glossy and not browning, and at the same time keep the elasticity of meat.
4. Bulking agent: GDL is paired with sodium bicarbonate and mixed to make baking powder. When heated, gluconic acid reacts with sodium bicarbonate to produce carbon dioxide, which has good puffing effect and no odor, especially suitable for pastry and fried food.
5. chelating agent and stabilizer: GDL can be used to prevent the formation of tartar in fruit juice, wine and other beverages, and as a pigment stabilizer to maintain the color of meat products.
6. pH regulator: GDL is able to regulate the acidity of food by slowly releasing gluconic acid, thus controlling the pH value.
