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.

  • E412 Guar gum Guar gum is a thickener ground from the seeds of the guar plant.
  • E415 Xanthan gum Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris.
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.

  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
