It is a curious fact that the volatile oil to which mixedmustard owes its aroma and pungency does not exist in theseed itself, but is formed, during the process of mixing, froma tasteless substance through the action of an enz;yTne.

Hence, if drymustard be sifted into boiling water no pungency is developed. 134 FLA\()RING AND BEVERAGE PLANTS.
