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.

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.
  • Gluten Wheat gluten, sold as "vital wheat gluten", is the protein washed out of wheat flour.

  • 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.
  • Vegetable oil Vegetable oils are pressed or extracted from seeds, nuts and fruits.
