Product Overview

Glucono Delta-Lactone (GDL), CAS No.:  90-80-2,  E No.: E575,   is a white crystalline food additive. When dissolved in water, it gradually hydrolyzes into gluconic acid, producing a mild and slow acidification effect. This property makes it widely used as a protein coagulant in dairy and cheese production. It also acts as acidulant and leavening component in bakery, and finds usage in meat products and other fields.

Core Characteristics

1.Slow-release acidification — gradually lowers pH over time, avoiding rapid acid shock

2.Mild and clean taste, no harsh sourness

3.Freely soluble in water, easy to dissolve and distribute

4.White crystalline powder, suitable for precise dosing in industrial production

Main Functions

1.Protein Coagulant:  GDL slowly releases gluconic acid in aqueous systems, gradually lowering pH and gently coagulating milk proteins and soy proteins. This slow and uniform acidification produces smooth, delicate curd texture without rapid precipitation, making it ideal for cheese and dairy products.

2.Slow-Release Acidulant Acts as a mild acid source in food formulations, providing gradual pH reduction rather than immediate acidification.

3.Leavening Component Serves as the acidic component in baking powder systems, reacting slowly to release carbon dioxide for uniform leavening.

4.Chelating & Antioxidant Helps chelate metal ions and supports color stability in meat products.

Applications

1.Cheese & Dairy Products:  Widely used in cottage cheese, cream cheese and other fresh cheese varieties. The slow acidification of GDL coagulates milk proteins gently, producing fine, smooth curd texture and consistent product quality. It is also applied in yogurt and fermented dairy products to assist and stabilize acidification.

2.Bakery Products Used in baking powder and self-rising flour as a slow-release acid component, ensuring steady gas release and uniform volume in bread, cakes and pastries.

3.Meat Products  Applied in sausages and cooked meats as chelating agent and color stabilizer.

4.Tofu Production  Used as coagulant in tofu making to produce delicate soybean curd.

5.Other Fields  Also has applications in cosmetics and pharmaceutical industries.
