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.

  • E1400 Dextrin Dextrin is starch partly broken down by heat or acid, used as a thickener, binder and coating.
  • E415 Xanthan gum Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris.
  • E450 Diphosphates Diphosphates are phosphate salts used as raising agents in baking powder, and to hold water in processed meats and cheese.
  • Thickener Thickeners, often gums or modified starches, make liquids more viscous so that a product feels richer than its ingredients alone would make it.
  • 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.
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.
  • Vegetable oil Vegetable oils are pressed or extracted from seeds, nuts and fruits.
