Popis: | Sea buckthorn berries contain lipids rich in palmitoleic acid, carotenoids, tocols and sterols, but their composition varies greatly depending on the cultivar and region of cultivation. Therefore, the current study presents the chemical composition of fruit flesh oils of cultivars grown in Poland and compares them with plants grown worldwide. Among tested cultivars, the highest shares of palmitoleic acid were determined in Golden Rain and Luczystaja cvs. Ten grams of sea buckthorn flesh oil provides at least 28% of vitamin A, 50% of vitamin E and 5% of sterols of the recommended dietary allowance (RDA) values for adults. The final part of this study is dedicated to a preliminary study of the optimization of the oleosome yield by the centrifugation method. The maximum oleosome yield can be obtained at a relatively low centrifugal force (below 8000×g), while optimal temperature and time should be laboratory determined for each cultivar. |
