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.

  • E481 Sodium stearoyl-2-lactylate Emulsifiers are substances which make it possible to form or maintain a homogenous mixture of two or more immiscible phases such as oil and water in a foodstuff.
  • Emulsifier Emulsifiers keep fat and water from separating, giving products a smooth, stable texture over a long shelf life.
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.

  • Preservative Preservatives slow spoilage by microbes.
  • Salt Salt, added for taste and preservation.
  • Sugar Sugar refined from sugar cane or beet.
