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.

  • E951 Aspartame Aspartame is a synthetic sweetener about 200 times sweeter than sugar, used in diet drinks and sugar-free products.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
