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.

  • E450 Diphosphates Diphosphates are phosphate salts used as raising agents in baking powder, and to hold water in processed meats and cheese.
  • E471 Mono- and diglycerides of fatty acids Mono- and diglycerides of fatty acids are made from fats and glycerol.
  • Emulsifier Emulsifiers keep fat and water from separating, giving products a smooth, stable texture over a long shelf life.
  • Humectant Humectants are substances which prevent foods from drying out by counteracting the effect of an atmosphere having a low degree of humidity, or promote the dissolution of a powder in an aqueous medium.
1 ingredient that would only make it processed
