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.

  • E102 Tartrazine Tartrazine is a synthetic yellow azo dye (FD&C Yellow No. 5 in the US).
  • E129 Allura red Allura red AC is a synthetic red azo dye (FD&C Red No. 40 in the US).
  • E133 Brilliant blue FCF Brilliant blue FCF is a synthetic blue dye, listed in the US as FD&C Blue No. 1.
  • 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.
  • E471 Mono- and diglycerides of fatty acids Mono- and diglycerides of fatty acids are made from fats and glycerol.
  • E621 Monosodium glutamate Monosodium glutamate (MSG) is the sodium salt of glutamic acid, made by fermentation and used to strengthen savoury 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.

  • 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.
  • Lactose Lactose is milk sugar, crystallised industrially from whey, a by-product of cheese making.
  • Maltodextrin Maltodextrin is a white powder made by partly breaking down starch.
  • Whey Whey is the liquid left over from cheese making, usually dried into a powder and used as a cheap source of milk solids, protein and lactose.
