Glucono Delta Lactone E575

Product Overview

Glucono Delta Lactone (GDL, E575) is a mild acidulant and neutral-tasting coagulant produced by the fermentation of glucose. It gradually hydrolyses in aqueous solutions to form gluconic acid, offering controlled acid release and a clean flavour profile. In food manufacturing, GDL is valued for its pH-control, leavening, and protein-coagulating properties, enabling fine-tuned texture development in dairy, tofu, bakery, meat, and beverage formulations.

DextroDelight supplies high-purity, food-grade GDL ideal for small-batch processors, research labs, and clean-label food developers requiring precise acidification control.

Applications in Food Production

• Tofu & Dairy Alternatives: Acts as a natural coagulant in tofu production, forming smooth, tender curds without bitterness. Controls acidification in plant-based dairy formulations such as yoghurt and cream cheese.
• Bakery & Leavening Systems: Provides slow, controlled acid release for balanced leavening in cakes and bakery premixes. Enhances dough stability and extends shelf life when used with bicarbonates.
• Meat & Seafood Processing: Used to reduce pH gradually, improving protein binding and texture in cured meats and seafood. Helps retain moisture and enhance flavour stability.
• Beverages & Fermented Drinks: Adds mild acidity and freshness to functional beverages, kombucha, and fruit drinks. Supports flavour balance without overpowering tartness.
• Confectionery & Desserts: Improves gel firmness and acid balance in pectin-based jellies and gummies. Contributes to clean taste and consistent gelling in desserts.
• Ready Meals & Sauces: Maintains emulsification and product stability in heat-processed sauces, soups, and ready meals. Enhances microbial control through mild acidification.
