The aim of this paper was to establish similarities and differences between wafer to determine which of them can be stored together Both, two-way and one-factor analysis were performed. F-tests, assuming normality of the errors, and free distribution tests were carried out. The assumptions of the tests were verified. At 15 degrees C there exist some sorption differences that can be detected neither at 25 degrees C nor at 35 degrees C. In establishing which varieties can be stored together the study of the similarities and dissimilarities in sorption behaviour at a given temperature cannot be extrapolated to another temperature. These results show the importance of analysing sorption characteristics of cereals and oil seeds at different storage temperatures in order to decide adequately on storage policy.
