You'll need to take a close look at the small print on the ingredients list to find out what your food really contains. Most additives need to be declared in the ingredients list, but not all. Flavourings don't have to be listed by name, and certain additives used as processing aids escape listing altogether. Additives that don’t have to be declared include:
- solvents used to dilute other additives such as colourings and to extract flavours
- enzymes used in food processing
- processing aids such as those used to stop ingredients sticking to machinery and baking trays – traces of these additives may remain in the food
- packaging gases used to prolong the life of fresh foods.
