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.

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.
