For composite foods to be labelled as organic, at least 95% of the ingredients must come from organically produced plants or animals. EU-wide rules require organic foods to be approved by an organic certification body, which carries out regular inspections to ensure the food meets a strict set of detailed regulations, relating to production methods and labelling.

Look for labels like the Soil Association. This is the gold standard of organic labelling. As some ingredients are not available organically, a list of non-organic food ingredients are allowed however, all artificial colourings and sweeteners are banned completely in foods labeled as organic.
