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.

  • E322 Lecithins Lecithins are fatty substances extracted mostly from soybeans, sunflower seeds or eggs, used as emulsifiers to keep fat and water mixed, for example in chocolate.
  • E422 Glycerol Glycerol is a sweet-tasting liquid used to keep products moist and soft.
  • E955 Sucralose Sucralose is a sweetener made by chlorinating sugar.
  • E965 Maltitol Maltitol is a sugar alcohol made from starch, used as a sweetener in "no added sugar" sweets and chocolate.
  • Emulsifier Emulsifiers keep fat and water from separating, giving products a smooth, stable texture over a long shelf life.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.

  • Sweetener Sweeteners give sweetness with few or no calories, many at hundreds of times the strength of sugar.

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.
  • Cocoa powder An ingredient mostly produced industrially and rarely used in home kitchens.
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.
  • Milk powder Milk powder is milk with the water evaporated off: a preserved form of a whole food rather than an industrial extract.
