For the authentication and adulteration control the lipidomic approach was used. The samples of cow and/or soyabean milk and their mixtures were analyzed by supercritical fluidic chromatography coupled with high-resolution mass spectrometry. The obtained data were processed by statistical analysis. The results showed that the above approach and methods can be used for the determination of authenticity and adulteration control of cow and soyabean milk. The amount of foreign milk to the cow or soyabean milk can be also determined from the characte¬ristic triacylglycerol content. This procedure, which is described above, is able to is able to detect 1 % of cow milk in soyabean milk and vice versa.
