What is it?
calcium gluconate (INS 578) is a Acidity regulator, Firming agent, Sequestrant food additive. Used to regulate or maintain acidity (pH), affecting flavour, colour and stability.Used to maintain or enhance the firmness and crispness of fruits, vegetables and canned foods.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).Commonly calcium salts (e.g. calcium chloride, calcium lactate).E.g. citric acid and its salts occur naturally in citrus fruits.
Industrial：Their salts (e.g. sodium citrate, phosphates) are made by neutralisation.Also includes some aluminium salts (e.g. potassium aluminium sulphate).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
- Enhance firmness
- Keep produce crisp
- Improve canned-food quality
- Chelate metal ions
- Prevent oxidative discolouration
- Stabilise quality
Common Foods
- Beverages
- Confectionery
- Dairy
- Canned foods
- Bakery
- Canned fruits/vegetables
- Soy products
- Jam
- Pickled foods
- Edible oils
- Sauces
- Cured foods
Safety
Mostly organic acids naturally present in foods; safe within permitted use.Safe within permitted use; aluminium salts have scope restrictions.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。

In a nutshell
calcium gluconate is a Acidity regulator, Firming agent, Sequestrant, safe for use in food production within permitted limits.
