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.

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.

Dextrose Dextrose is pure glucose crystallised from starch-derived syrup.
Glucose Glucose, usually listed as glucose syrup, is cheap, keeps products moist and stops sugar from crystallising.

1 ingredient that would only make it processed
