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.

  • E415 Xanthan gum Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris.
  • E466 Sodium carboxy methyl cellulose Carboxymethyl cellulose is a thickener made by chemically modifying cellulose from wood or cotton.
  • E955 Sucralose Sucralose is a sweetener made by chlorinating sugar.
  • E960 Steviol glycosides Steviol glycosides are sweet compounds extracted and purified from the leaves of the stevia plant.
  • E968 Erythritol Humectants are substances which prevent foods from drying out by counteracting the effect of an atmosphere having a low degree of humidity, or promote the dissolution of a powder in an aqueous medium.
  • 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.

  • Milk proteins Milk proteins are proteins separated from milk, such as caseinates and whey protein concentrates, added to adjust texture or raise protein content.
  • Vegetable fiber Isolated plant fibres, such as inulin, oat fibre or bamboo fibre, are extracted industrially and added to change texture or support "source of fibre" claims.
2 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.

  • Salt Salt, added for taste and preservation.
  • Vegetable fat Vegetable fats are oils that are solid at room temperature, such as palm or coconut fat.
