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.

  • E150a Plain caramel Plain caramel is a brown colour made by heating sugars.
  • Colour Colours are added to restore colour lost in processing or to make a product look more appealing.
5 ingredients that would only make it processed

Kitchen staples like sugar, salt and oil. On their own they make a food processed, not ultra-processed.

  • E202 Potassium sorbate 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.
  • Preservative Preservatives slow spoilage by microbes.
  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
  • Sauce A prepared sauce used as an ingredient.
