Flavourings often contain carriers that are regulated and must not exceed certain limits in the finished product. This creates a dual responsibility for flavour companies to inform their customers of the proportions of these carriers in the flavour, and for the food and beverage industry to ensure that the limits are respected to protect their consumers.
For example, propylene glycol, which is widely used as a solvent in flavourings, must not be present at more than 3 g/kg in foodstuffs, and 1 g/l in beverages, either alone or in combination with triethyl citrate, diacetin and/or triacetin.
