What makes it ultra-processed
Cosmetic additives
Added to change how the food looks, feels or tastes, not to keep it safe. A hallmark of ultra-processed food.
- E621 Monosodium glutamate Monosodium glutamate (MSG) is the sodium salt of glutamic acid, made by fermentation and used to strengthen savoury taste.
- Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
