ical composition of biodiesel is dependent upon the feedstock from which it is produced, as vegetable oils and animal fats of differing origin have dissimilar fatty acid compositions (Table 1).

The intake of omega-6 vegetable oils, particularly soybean oil, began to increase in the USA starting in the early 1900s at a time when the consumption of butter and lard was on the decline.1 This caused a more than two-fold increase in the intake of linoleic acid, the main omega-6 polyunsaturated fat found in vegetable oils, which now makes up around 8% to 10% of total energy intake in the .... The unsaponifiables from 19 vegetable oils were divided into a sterol and three other fractions by thin-layer chromatography. All except olive and palm kernel oils gave the sterol fraction in a large quantity. Compositions of the sterol fractions were determined by gas liquid chromatography. Identification of each sterol was carried out by gas liquid chromatography and combined gas .... represent a subcategory of hydrotreated vegetable oil (HVO) biofuels. HVOs are notably distinct to fatty acid methyl ester (FAME) biodiesels which retain an oxygen ester and are therefore too oxygenated to be a drop-in biofuel. Vegetable oils contain about 10 wt% oxygen and this oxygen has to be removed to produce drop-in HVO biofuels.. The fatty acid ester composition of the vegetable oil was determined by a gas chromatographic analysis procedure using methyl ester derivatives of the different vegetable oils prepared as described previously [17,18].
