(MVA)-principal component anal. (PCA) and cluster anal.-for the anal. of chromatog. and sensory data was investigated for volatiles of plant oils. Five oils-rapeseed, soybean, peanut, sunflower and olive oil-were compared. Volatile compds. of fresh oils and oils subjected to storage at 60 °C were isolated by HS-SPME sampling and analyzed by GC/MS, and fast GC with FID detection. Based on developed methods and data treatment it was possible to distinguish between different oils and oils stored for various periods of time. PCA of chromatog. data was related to PCA sensory anal. and similarities in sample clustering were obsd. Multivariate anal. facilitates comparison of chromatog. profiles of volatile compds. characteristic for various plant oils and for monitoring oil quality in storage.Except for chemicals metioned above, 17312-80-0 and 110-62-3 are also used. .
