What is it?
glucono delta-lactone (INS 575) is a Acidity regulator, Raising agent, Sequestrant food additive. Used to regulate or maintain acidity (pH), affecting flavour, colour and stability.Releases gas on heating or with water to make dough/batter rise.Binds metal ions to prevent oxidation, discolouration or deterioration catalysed by metals.
Source
Natural：Mostly organic acids naturally present in foods (e.g. citric, malic, lactic acid).E.g. sodium bicarbonate, ammonium bicarbonate.E.g. citric acid and its salts occur naturally in citrus fruits.
Industrial：Their salts (e.g. sodium citrate, phosphates) are made by neutralisation.Includes aluminium-containing or aluminium-free baking powders.Synthesised from the corresponding acids or salts (e.g. EDTA salts, phosphates).
Why is it used?
- Adjust pH
- Improve flavour
- Enhance preservation and colour stability
- Make dough rise
- Create light texture
- Improve mouthfeel
- Chelate metal ions
- Prevent oxidative discolouration
- Stabilise quality
Common Foods
- Beverages
- Confectionery
- Dairy
- Canned foods
- Bakery
- Steamed buns
- Cakes
- Biscuits
- Fried dough
- Edible oils
- Sauces
- Cured foods
Safety
Mostly organic acids naturally present in foods; safe within permitted use.Safe within permitted use; aluminium-containing types require aluminium-residue control.Safe within permitted use; excessive phosphate intake may affect calcium–phosphorus balance.
Metabolism：Metabolic pathways vary by substance; generally the material is metabolised or excreted normally.
Concerns：
- Use within permitted levels
- Sensitive individuals should check the ingredient list
Usage Standard
China：依据 GB 2760《食品安全国家标准 食品添加剂使用标准》确定使用范围与最大使用量；具体限值随食品类别而异。
