Ultra-processed food
Almost all food is processed in some way. The term ultra-processing refers to the processing of industrial ingredients derived from foods, for example by extruding, moulding, re-shaping, hydrogenation, and hydrolysis. Ultra-processed foods generally include additives like preservatives, sweeteners, sensory enhancers, colourants, flavours, and processing aids. Infant formula and medical food are also considered ultra-processed. Food additives are not always a marker of ultra-processed foods. Preservatives, for example antioxidant or nitrite, are permitted for category 3.
