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.

  • E171 Titanium dioxide Titanium dioxide is a white pigment.
  • 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.
  • E428 Gelatine Gelatine is a gelling agent made from collagen in animal skin and bones.
  • E452 Polyphosphates Emulsifiers are substances which make it possible to form or maintain a homogenous mixture of two or more immiscible phases such as oil and water in a foodstuff.
  • Colour Colours are added to restore colour lost in processing or to make a product look more appealing.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.

  • Modified starch Modified starch is starch altered physically, with enzymes or chemically, so that it thickens, gels or survives freezing and heating better than ordinary starch.

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.
  • High fructose corn syrup High-fructose corn syrup is made from corn starch: enzymes break it down to glucose and convert part of that into fructose, giving a syrup about as sweet as table sugar.
  • Fructose Fructose is the sugar found naturally in fruit and honey, but as an ingredient it is refined industrially, mostly from corn starch.
  • Cocoa An ingredient mostly produced industrially and rarely used in home kitchens.
3 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.
  • Starch Starch extracted from cereals or potatoes, used to thicken.
  • Sugar Sugar refined from sugar cane or beet.
