Glucono Delta Lactone(GDL)
SINOBIO
2932209090
Glucono Delta Lactone (GDL, CAS 90-80-2) is a white crystalline powder with the chemical formula C₆H₁₀O₆. It possesses various functional properties and is widely used in the food, cosmetic, and industrial fields. The following is a detailed description:
*Chemical Name: Glucono Delta Lactone
*Molecular Weight: 178.14 g/mol
*Melting Point: 150–153°C
*Solubility: Easily soluble in water (solubility 59 g/100 mL at 25°C), insoluble in ether.
*Appearance: White crystalline powder, almost odorless, with an initially sweet taste followed by a sour taste.
*Stability: Stable in a dry environment, decomposes at around 153°C. Slowly hydrolyzes in aqueous solution to gluconic acid, forming a dynamic equilibrium.
Terms | Specifications | Result |
Identification | Positive | Pass |
Appearance | Fine, White, Crystalline power odorless | Pass |
Assay | 99.0~100.50% | 99.56 % |
Water(Karl Fischer method) | ≤0.5% | <0.1% |
Reducing substances(as D-glucose) | ≤0.5% | <0.1% |
Lead(Pb) | ≤2ppm | 0.05ppm |
Heavy Metals | ≤20ppm | <10ppm |
As | ≤10ppm | 0.05ppm |
Sulphate Ash | ≤0.1% | 0.05% |
Particle size | 25-100mesh | Pass |
*Acidifying Agents and pH Adjusters:
- Used in dairy products such as cheese and yogurt to slowly lower the pH value, inhibit microbial growth, and extend shelf life.
- Adjusts acidity and improves flavor in salad dressings and instant noodles/rice.
*Coagulants:
- Tofu production: Replaces traditional brine or gypsum; mixes directly with hot soy milk and is packaged, reducing the risk of microbial contamination; the finished product is delicate, smooth, and has strong water retention.
- Meat products: Acts as a coagulation accelerator, improving the water retention and elasticity of sausages and luncheon meat, while inhibiting the formation of nitrosamines.
*Leaving Agents:
- Combined with sodium bicarbonate (baking soda), used in baked goods such as cakes and cookies. Reacts with carbon dioxide upon heating, making the product fluffy and odorless.
*Chlorinating Agents:
- Prevents tartrate precipitation in grape juice and fruit wine, and milkstone formation in dairy products.
*Skin Conditioner:
- Used as a mild acidifier in skincare products (such as serums and lotions) to adjust the product's pH value and enhance skin absorption.
- Recommended dosage: 0.1%–5.0%. A 1% aqueous solution will have a pH of approximately 3.0–4.0 (gradually decreasing over 60 minutes).
*Preservative Enhancer:
Works synergistically with sodium benzoate, potassium sorbate, etc., to enhance preservative effects and reduce the amount of a single preservative required.
*Hair Care:
Used in shampoos and conditioners to improve hair shine and smoothness.
*Cleaners and Detergents:
- Used as a chelating agent to remove oxides from metal surfaces, improving cleaning efficiency.
*Water Treatment:
Prevents the precipitation of calcium and magnesium ions in cooling water systems, reducing equipment scaling.
