摘要
The changes in the content and composition of total fatty acids, phospholipids and sterol esters, and their fatty acids, and of free sterols and tocopherols in developing seeds of a selection of high oleic acid sunflower varieties grown in Bulgaria were examined over a period of 15th to 90th day after flowering by means of various chromatographic methods. Under the climatic and geographical conditions typical for the South-East Balkans phospholipid, sterol-, sterol ester- and tocopherol- species are formed practically completely in the first 15 days after flowering. Until the 90th day, only quantitative changes were detected to give a product with 65%oil content, 1%phospholipids, 0.3%total sterols and 0.09%tocopherols. Oleic acid is the main component in all acyl derivatives, reaching 85%of the total fatty acids while palmitic and stearic acid content is about 4%each. The product is a good quality HOSO with beneficial content of FA and good prospects as a salad and cooking oil.
