Popis: | The objective of this study was to investigate the impact of the storage time, content of the husk and impurities in the seed mass on the oxidative stability of the cold pressed sunflower oil. The oxidative stability of oil was analyzed by the RSM (Response Surface Methodology), where the response value (output) of the model was the content of oxidation products measured via specific absorbance at 232 nm for conjugated dienes and 270 nm for conjugated trienes. Analyses were performed on the fresh oil samples and oil samples tempered under the Schaal-Oven?s test conditions (96 h at 63?2?C). It was concluded that the seed storage time had significant impact on the primary (A1%232nm) and secondary (A1%270nm) oil oxidation products, both before (b1-p |
