What is it?
calcium bisulfite, calcium hydrogen sulfite (INS 227) is a Preservative, Antioxidant food additive. Used to inhibit the growth of microorganisms (bacteria, yeasts, moulds) and extend shelf life.Used to slow or prevent oxidative deterioration, discolouration and rancidity.
Source
Natural：Some occur naturally in foods or are produced by microbial fermentation (e.g. lactic acid, natamycin).Some occur naturally in plants and animals (e.g. vitamin C, vitamin E, tea polyphenols).
Industrial：Most are produced synthetically from the corresponding acids, salts or esters (e.g. benzoates, sorbates, nitrites).Some are synthesised or purified (e.g. ascorbyl palmitate, TBHQ).
Why is it used?
- Inhibit moulds, yeasts and bacteria
- Extend shelf life
- Reduce spoilage and foodborne risks
- Delay fat oxidation/rancidity
- Preserve colour and flavour
- Protect oxidisable nutrients
Common Foods
- Cured meat
- Beverages
- Jams
- Pickled foods
- Bakery
- Edible oils
- Fat-based products
- Meat products
- Nuts
- Snack foods
Safety
Approved by multiple authorities within permitted limits; excessive intake may pose health risks, so maximum use levels must be strictly observed.Most are nutrients or generally recognised as safe within permitted use; some synthetic antioxidants have scope restrictions.
Metabolism：Metabolic pathways vary by substance; generally the material is metabolised or excreted normally.
