The aim of research was to determine the effect of heat treatment of whole and milled seeds and methods of extraction on the content of phosphorus and profile of phospholipids. The experimental material consisted of 15 laboratory samples of rapeseed oil, and 1 sample of industrial hot-pressed oil. The phosphorus content, the share of phospholipids with column chromatography and the profile of phospholipids with thin layer chromatography were determined. The methods of oil extraction had a significant impact on the content of phosphorus and the profile of phospholipids, while the most significant to the share of PA. It was found that the heat treatment of seeds increased the content of phosphorus, share of total PL and PA in the samples of cold-pressed and extracted with petroleum ether oils.

Celem badań było określenie wpływu obróbki termicznej całych i rozdrobnionych nasion rzepaku, jak również metody wydobywania oleju na udział i profil fosfolipidów. Materiał badań stanowiło 15 laboratoryjnych próbek oleju rzepakowego i jedna przemysłowa próbka oleju tłoczonego na gorąco. W olejach określono skład lipidowy metodą chromatografii kolumnowej oraz profile fosfolipidowe metodą chromatografii cienkowarstwowej. Metoda wydobywania oleju miała istotny wpływ na zawartość fosforu oraz udział i profil fosfolipidów, z czego w największym stopniu na udział PA. Stwierdzono, iż ogrzewanie nasion rzepaku wpłynęło na zwiększenie zawartości fosforu oraz ogólny udział PL i udział PA w próbkach tłoczonych na zimno i ekstrahowanych eterem naftowym.
