Özet
In the present work deodorizer distillates of canola and sunflower oil were studied for their chemical characterization. Tocopherols, sterols, hydrocarbons and fatty acid composition were determined by Gas chromatography Mass spectrometry (GC-MS). Results indicated that deodorizer distillates of canola oil (DDCLO) studied had higher saponification value in the range of 164.2-175.8 mg/g and all deodorizer distillates of sunflower oil (DDSFO) had high iodine value of 126.2-127.1 g/100 g. Peroxide value and free fatty acids were present in the range between 7.0-8.9 mEq/Kg and 35.7-54.4 g/100 g in DDSFO and DDCLO samples, respectively. Contents of oleic acid (49.3-51.1 g/100 g) and linolenic acid (6.2-7.5 g/100 g) were significantly greater in DDCLO samples. Conversely, DDSFO contained concentrated amount of linoleic acid (52.8-53.3 g/100 g). Tocopherols and hydrocarbons were significantly higher in all DDSFO samples while, sterols were dominant in DDCLO samples. GC MS provided excellent results for simultaneous determination of tocopherols, sterols, hydrocarbons and fatty acid composition of deodorizer distillates of canola and sunflower oil.
