What is it?
sodium gluconate (INS 576) is a Sequestrant, Stabilizer, Thickener food additive. Binds metal ions to prevent oxidation, discolouration or deterioration catalysed by metals.Used to keep the physical state of foods stable, preventing separation, sedimentation or syneresis.Used to increase viscosity and improve mouthfeel and body.
Source
Natural：E.g. citric acid and its salts occur naturally in citrus fruits.Mostly natural gums, proteins or polysaccharides (e.g. gelatin, pectin, locust bean gum).Mostly natural polysaccharides or proteins (e.g. pectin, xanthan, carrageenan, starch).
Industrial：Synthesised from the corresponding acids or salts (e.g. EDTA salts, phosphates).Some are physically or chemically modified (e.g. carboxymethyl cellulose, modified starches).Some are modified for performance (e.g. hydroxypropyl starch, CMC).
Why is it used?
- Chelate metal ions
- Prevent oxidative discolouration
- Stabilise quality
- Maintain homogeneity
- Prevent syneresis and sedimentation
- Improve texture and water retention
- Increase viscosity
- Improve body and mouthfeel
- Stabilise suspensions
Common Foods
- Canned foods
- Edible oils
- Beverages
- Sauces
- Cured foods
- Yoghurt
- Jelly
- Ice cream
- Soups
Safety
Safe within permitted use; excessive phosphate intake may affect calcium–phosphorus balance.Most act as dietary fibre or inert colloids and are safe within permitted use.Mostly indigestible polysaccharides, safe within permitted use; some act as dietary fibre.
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。

In a nutshell
sodium gluconate is a Sequestrant, Stabilizer, Thickener, safe for use in food production within permitted limits.
