Popis:	Olive oil was hydrogenated to an iodine value (I.V.) of ca. 50 under widely differeing operating conditions. Three types of catalyst were employed. Each catalyst was used at the lowest possible operating temp and at 170C. The hydrogenated samples were subjected to lipase hydrolysis to remove a portion of the acyl groups in the 1,3-positions, and the fractions obtained, as well as the unhydrolyzed samples, were analyzed for fatty acid composition and content oftrans mononenes. From these data it was concluded that the position of the oleoyl group in the triglyceride molecule is not a factor in the rate of hydrogenation or isomerization.
