Introduce
Glucono-Delta-Lactone (GDL) is a commonly used food acidifier and food additive. It is a lactone compound produced from glucose through an oxidation reaction. The following are the main applications of gluconolactone in the food field:
Acidifier: Gluconolactone can act as an acidifier in food by converting it to gluconic acid. Gluconic acid is a kind of mild acid, which can adjust the acidity and pH value of the food, and enhance the sour taste and texture of the food. It is widely used in bread, cakes, pastries, jellies, dairy products and other foods for regulating acidity and extending the shelf life of foods.
Gelator: Gluconolactone can react with protein to form a gel under certain conditions. This process of gel formation usually requires acidic conditions. Therefore, gluconolactone is often used as a coagulant for foods such as tofu and coagulated dairy products (e.g., coagulated yoghurt).
Flavouring agent: Gluconolactone has a special acidic taste that enhances the taste and flavour of foods. It is often used as a flavouring agent and added to a variety of foods, such as sauces, meat products, seasonings, etc., to enhance the flavour and texture of the food.
Dough regulator: Gluconolactone can react with the starch in the dough to improve the texture and ductility of the dough. It is widely used in bread, cakes and other baked goods to improve the processing properties and texture of dough.
