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.
  • E170 Calcium carbonates Calcium carbonate is chalk.
  • 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.
  • E415 Xanthan gum Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris.
  • E422 Glycerol Glycerol is a sweet-tasting liquid used to keep products moist and soft.
  • E428 Gelatine Gelatine is a gelling agent made from collagen in animal skin and bones.

  • E450 Diphosphates Diphosphates are phosphate salts used as raising agents in baking powder, and to hold water in processed meats and cheese.
  • Colour Colours are added to restore colour lost in processing or to make a product look more appealing.
  • 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.
  • Humectant 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.

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.

  • Dextrose Dextrose is pure glucose crystallised from starch-derived syrup.
  • 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.
  • Invert sugar Invert sugar is ordinary sugar split into glucose and fructose with acid or enzymes.
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.

  • Preservative Preservatives slow spoilage by microbes.
  • Salt Salt, added for taste and preservation.
  • Starch Starch extracted from cereals or potatoes, used to thicken.
  • Sugar Sugar refined from sugar cane or beet.
  • Sweet snacks Products in the category "Sweet snacks" are at least group 3.
