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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Sweet snacks Products in the category "Sweet snacks" are at least group 3.
