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.

  • E407 Carrageenan Carrageenan is a thickener and gelling agent extracted from red seaweed, used widely in dairy desserts, plant-based drinks and processed meats.
  • E410 Locust bean gum Locust bean gum (carob gum) is a thickener and stabiliser from the seeds of the carob tree.
  • E412 Guar gum Guar gum is a thickener ground from the seeds of the guar plant.
  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a 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.

  • Maltodextrin Maltodextrin is a white powder made by partly breaking down starch.
2 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.

  • Ice creams Products in the category "Ice creams" are at least group 3.
  • Sugar Sugar refined from sugar cane or beet.
