What is it?
sodium, potassium and calcium salts of fatty acids (INS 470a) is a Emulsifier, Stabilizer, Anticaking agent food additive. Allows immiscible liquids (e.g. oil and water) to form a stable uniform system, improving texture.Used to keep the physical state of foods stable, preventing separation, sedimentation or syneresis.Used to prevent caking of powdered or granular foods and maintain flowability.
Source
Natural：Some derive from natural raw materials (e.g. soy lecithin, egg-yolk phospholipids).Mostly natural gums, proteins or polysaccharides (e.g. gelatin, pectin, locust bean gum).Inert inorganic substances such as aluminosilicates, silica, magnesium carbonate.
Industrial：Many are made by esterifying glycerol with fatty acids or further derivatisation (e.g. monoglycerides, spans, tweens).Some are physically or chemically modified (e.g. carboxymethyl cellulose, modified starches).Purified or synthesised.
Why is it used?
- Stabilise oil-water emulsions
- Improve mouthfeel and structure
- Prevent separation
- Maintain homogeneity
- Prevent syneresis and sedimentation
- Improve texture and water retention
- Prevent caking
- Maintain flowability
- Ease dosing and dispersion
Common Foods
- Margarine
- Ice cream
- Bakery
- Chocolate
- Sauces
- Yoghurt
- Beverages
- Jelly
- Salt
- Icing sugar
- Milk powder
- Instant drink powders
- Seasonings
Safety
Largely metabolised in the gut; generally safe within permitted use; JECFA sets ADI where applicable.Most act as dietary fibre or inert colloids and are safe within permitted use.Mostly inert inorganic, non-absorbable, safe within permitted use.
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
