ABSTRACTPresently, several chemical tests are used to determine the quality of canned tuna. The need for developing a single test motivated this research, Profiles of canned tuna volatiles were obtained using high resolution gas chromatography. A high correlation between the volatile profile and sensory panel scores was obtained. Two models based on three or five major peaks were developed for predicting quality scores. Using such models, correlation coefficients of 0.90 and 0.91 have been obtained. The error associated with predicted sensory scores using such models was in the order of to.5 unit. Such error has the same magnitude as the inherent error associated with taste panel itself.
