What is it?
oxystearin (INS 387) is a Antioxidant, Sequestrant food additive. Used to slow or prevent oxidative deterioration, discolouration and rancidity.Binds metal ions to prevent oxidation, discolouration or deterioration catalysed by metals.
Source
Natural：Some occur naturally in plants and animals (e.g. vitamin C, vitamin E, tea polyphenols).E.g. citric acid and its salts occur naturally in citrus fruits.
Industrial：Some are synthesised or purified (e.g. ascorbyl palmitate, TBHQ).Synthesised from the corresponding acids or salts (e.g. EDTA salts, phosphates).
Why is it used?
- Delay fat oxidation/rancidity
- Preserve colour and flavour
- Protect oxidisable nutrients
- Chelate metal ions
- Prevent oxidative discolouration
- Stabilise quality
Common Foods
- Edible oils
- Fat-based products
- Meat products
- Nuts
- Snack foods
- Canned foods
- Beverages
- Sauces
- Cured foods
Safety
Most are nutrients or generally recognised as safe within permitted use; some synthetic antioxidants 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
