Yes — All-Butter Welsh Cakes is ultra-processed.
Not ideal for everyday eating because it contains industrial fats and additives.
This product is classified as ultra-processed because it contains the pre-identified UPF ingredients palm fat and the raising agents disodium diphosphate and potassium hydrogen carbonate. Palm fat is a highly processed refined fat, while these industrial raising agents are additives that contribute to the UPF classification. The fortified wheat flour, butter, sugar, egg, currants, and spices do not independently make it UPF.
