Abstract Swede cultivars can be differentiated by their volatile hydrolysis products obtained after maceration. Multivariate statistical techniques however, are required to interpret the data because of the interactions between volatiles. Canonical variate analysis allowed a chemical interpretation to be placed on the effects of storage and provided a basis for differentiating between cultivars. The relative chemical configuration of the cultivars is displayed graphically by plotting the cultivar means relative to the first two canonical variates.
