Differentiation of milk by fatty acid spectra and principal component analysis

109 FAMEs could be separated. By PCA and PLS-DA a clear distinction between the two groups of milk samples was possible. By evaluation of correlation loadings an estimation of the contribution of distinct FAMEs to the characterization of samples was possible. Among others most odd chained, saturated and unsaturated C18 FAMEs - especially C18:2c9t11 conjugated linoleic acid were significantly different in the two groups of samples.
