Glucono-Delta-Lactone (E575)

Glucono Delta Lactone

Glucono delta lactone is a slow-release acidulant and sequestrant formed through glucose fermentation that gradually hydrolyzes to gluconic acid over 1-2 hours, providing controlled pH reduction, protein coagulation, and mineral chelation without initial sourness. In the food industry, it excels as a clean-label processor for silken tofu production, natural leavening in bakery, and stabilizer in dairy with pH drop from 6.0 to 3.5 over time, heat stability up to 120°C, and no off-flavors during extended reactions.

Food Industry Applications

• Tofu and soy products: Triggers smooth protein coagulation in silken tofu and soy puddings forming delicate gels during heating, creates uniform texture without bitterness, and maintains stability during storage.

• Bakery products: Acts as natural dough conditioner and leavening acid improving crumb softness and extending mold-free shelf life through gradual pH control.

• Dairy products: Stabilizes yogurt and cheese cultures preventing over-acidification, improves texture by sequestering calcium ions, and controls whey separation.

• Meat products: Provides gradual pH reduction in brines and marinades enhancing water binding and cure color development with clean acid profile.

• Confectionery and gels: Enables controlled setting in pectin-based gums and licorice maintaining clear texture and heat stability during processing.

• Beverages and sauces: Sequesters metal ions preventing oxidation and haze while providing gradual acidity buildup and protein stabilization.

Other Industry Applications

In cosmetics, acts as mild exfoliant and pH buffer in cleansers and toners; in pharmaceuticals, serves as chelating agent and controlled-release matrix; in personal care, stabilizes formulations; in industrial uses, processes textiles and metal cleaning.
