该方法的基础是通过ISO 948中规定的方法获得的实验室样品。测定原理在于研磨先前混合的实验室样品，以获得符合国际标准规定尺寸的颗粒，适用于香料或有关调味品，或如果没有规定，获得尺寸大约为1毫米的颗粒

Basis for this method is the laboratory sample obtained by the method specified in ISO 948. The principle of determination consists in grinding the laboratory sample, which has been previously mixed, to obtain particles of the size specified in the International Standard appropriate to the spice or condiment concerned or, if not so specified, to obtain particles of size approximately 1 mm.
