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.

E471 Mono- and diglycerides of fatty acids Mono- and diglycerides of fatty acids are made from fats and glycerol.

4 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.

E202 Potassium sorbate Preservatives are substances which prolong the shelf-life of foods by protecting them against deterioration caused by micro-organisms and/or which protect against growth of pathogenic micro-organisms.
Preservative Preservatives slow spoilage by microbes.
Salt Salt, added for taste and preservation.
Sugar Sugar refined from sugar cane or beet.
