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.
  • E466 Sodium carboxy methyl cellulose Carboxymethyl cellulose is a thickener made by chemically modifying cellulose from wood or cotton.
  • 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.
  • Maltodextrin Maltodextrin is a white powder made by partly breaking down starch.
  • 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.
  • Fructose Fructose is the sugar found naturally in fruit and honey, but as an ingredient it is refined industrially, mostly from corn starch.
  • Dutch Cocoa An ingredient mostly produced industrially and rarely used in home kitchens.
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.

  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
  • Vegetable fat Vegetable fats are oils that are solid at room temperature, such as palm or coconut fat.
  • Sweet snacks Products in the category "Sweet snacks" are at least group 3.
  • Milk powder Milk powder is milk with the water evaporated off: a preserved form of a whole food rather than an industrial extract.
