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.
Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
Modified starch Modified starch is starch altered physically, with enzymes or chemically, so that it thickens, gels or survives freezing and heating better than ordinary starch.

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.

Salt Salt, added for taste and preservation.
Starch Starch extracted from cereals or potatoes, used to thicken.
Sugar Sugar refined from sugar cane or beet.
Sauce A prepared sauce used as an ingredient.
