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.

E621 Monosodium glutamate Monosodium glutamate (MSG) is the sodium salt of glutamic acid, made by fermentation and used to strengthen savoury 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.

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.

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.
