    Abstract

    Practical knowledge acquired during a decade of devising methods for the correlation of sensory evaluation for flavor with gas-liquid chromatographic analysis of food volatiles is described. The evolution of methods, precautions that should be taken with each method, limitations of the methods, and minimizing of experimental error on the sensory and objective sides are discussed.
