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.
  • Emulsifier Emulsifiers keep fat and water from separating, giving products a smooth, stable texture over a long shelf life.

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.
  • Glucose syrup 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.
  • 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.
