Cosmetic additives

Added to change how the food looks, feels or tastes, not to keep it safe. A hallmark of ultra-processed food.

E950 Acesulfame k Acesulfame K is a synthetic sweetener about 200 times sweeter than sugar, often combined with aspartame or sucralose.
Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
