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.

  • E150c Ammonia caramel Ammonia caramel is a brown colour made by heating sugars with ammonia compounds.
  • E635 Disodium 5'-ribonucleotide A food additive authorised for industrial food production.
  • Colour Colours are added to restore colour lost in processing or to make a product look more appealing.
  • Flavour enhancer Flavour enhancers such as monosodium glutamate (E621) strengthen savoury taste without adding a flavour of their own.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.

Substances rarely used in home kitchens

Refined or extracted in factories, such as syrups made from starch or isolated proteins. The other hallmark of ultra-processed food.

  • Whey Whey is the liquid left over from cheese making, usually dried into a powder and used as a cheap source of milk solids, protein and lactose.
