    Abstract

    Correlations between sensory and instrumental techniques are discussed in terms of specific requirements. Empirical correlations may not reflect a valid relation between the measured sensory property and the objective technique. A cause-effect relationship between instrumental and sensory measurements is much more difficult to establish, and the requirements for such a relationship depend on the particular problem. No simple set of rules can insure success in relating these two types of measurement. A series of examples illustrating the requirements for coordinating GLC and sensory measurements on Delicious apple essence are given.
