The market for natural flavours has grown tremendously over the past couple of years due to increase awareness of health coupled with emerging middle class across the globe. Flavours are used in food and beverages in order to enhance the taste and quality of the products. Thousands of natural volatile compounds make up the flavours and aromas of the food products that we eat in our day to day life. The definition of "natural flavour" under the Code of Federal Regulations is: "the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavouring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavouring rather than nutritional". The market is buoyant for the coming years especially in Europe for the natural and clean label flavours.
