changes in vitamin E content after storage differed between the genotypes, and these differences are likely to be explained by the different initial content of vitamin E in the respective genotypes before storage. Furthermore, each genotype appeared to have a different fatty acid and liqid profile, indicating different ratios between unsaturated and saturated fatty acida (data not shown). Indeed, the discrimination between samples before and after storage observed in the PCA plots derived from the ATP-MIR analysis appears to be due to differences in the frequencies associated with methyl groups, particularly in liqids. Biochemical reactions changing the frequencies of methyl group in lipids and the tocols possibly associated with them maay therefore occur during storage.
