From an ancient time people have been colouring food, drug and cosmetic products. Like, our ancestor used colour such as saffron to colour certain food. Also many behavioral studies show that the human appetite and choice of food are influenced by colours. Thus people all over the world are using food colours to give a pleasant look to their foods.
A Primary Food colour is water-soluble, and exhibits colouring power when it is dissolved. Synthetic Food colours are in more use than the Natural colours, because of availability of wide hue range and competitive prices.
