Profilograms based on the quantitative descriptive analysis (QDA) of jamun using nine attributes were drawn for four market samples and ten samples prepared using various instant mixes available in the local market. The instrumental texture measurement of shear values were determined for all the samples. Correlations between sensory and instrumental texture measurement (shear force) were studied. The shear values were found to be correlated positively with softness, juiciness and milkiness. Further canonical discriminant analysis was run to position the samples in relation to others. The results indicated that samples M1, M2, M4, S3, S4, S6 and S10 group together in the same quadrant which represents desirable attributes of jamun viz, color, softness, juiciness, milkiness and overall quality. The jamuns from the instant mixes (S) can replace the control samples, traditionally prepared market samples (M) as they match the product profile very closely.
