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.

  • E160b Annatto Colours are substances which add or restore colour in a food, and include natural constituents of foods and natural sources which are normally not consumed as foods as such and not normally used as characteristic ingredients of food.
  • E621 Monosodium glutamate Monosodium glutamate (MSG) is the sodium salt of glutamic acid, made by fermentation and used to strengthen savoury taste.
  • 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.

  • Glucose Glucose, usually listed as glucose syrup, is cheap, keeps products moist and stops sugar from crystallising.
  • Glucose syrup Glucose syrup is cheap, keeps products moist and stops sugar from crystallising.
  • Milk proteins Milk proteins are proteins separated from milk, such as caseinates and whey protein concentrates, added to adjust texture or raise protein content.
