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.

  • E150d Sulphite ammonia caramel Sulphite ammonia caramel is the dark brown colour in colas and many sauces, made by heating sugars with sulphite and ammonia compounds.
  • E290 Carbon dioxide Preservatives are substances which prolong the shelf-life of foods by protecting them against deterioration caused by micro-organisms and/or which protect against growth of pathogenic micro-organisms.
  • E950 Acesulfame k Acesulfame K is a synthetic sweetener about 200 times sweeter than sugar, often combined with aspartame or sucralose.
  • E951 Aspartame Aspartame is a synthetic sweetener about 200 times sweeter than sugar, used in diet drinks and sugar-free products.
  • E952 Cyclamic acid and its Na and Ca salts Sweeteners are substances used to impart a sweet taste to foods or in table-top sweeteners.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
