Wpływ tłoczenia na zimno roślin oleistych na jakość wytłoczonego oleju
Języki publikacji
The aim of this work was to evaluate the physical properties of oils from winter rape, pumpkin and grape seeds in order to assess their potential as a source of functional oils. Seeds were analysed for water content, protein and fat. All the seeds met minimum requirements for technological quality. The effect of cold oil extraction on chemical compounds was studied in oils pressed from the above seeds. The properties of the oils were compared based on the lipid profiles, content of carotenoids, chlorophylls and tocopherols. The oxidation stability of the oils was estimated through the determination of the acid number, peroxide number and oxidation induction time.
Zamierzeniem pracy było określenie parametrów fizycznych olejów z rzepaku ozimego, dyni i winogron w celu oceny ich potencjału jako źródła olejów funkcjonalnych. Nasiona analizowano na zawartość wody, białka i tłuszczu. Parametry nasion spełniały minimalne wymagania technologiczne. Badano zawartość związków chemicznych uzyskanych z powyższych nasion w olejach tłoczonych na zimno. Właściwości olejów porównano na podstawie zawartości lipidów, karotenoidów, chlorofili i tokoferoli. Stabilność oksydacyjną tych olejów oszacowano przez oznaczenie liczby kwasowej, liczby nadtlenkowej oraz czasu indukcji utleniania.
