The effects of hydrogenation on the stability of pilot plant refined and deodorized northern and southern sunflowerseed oil were studied. Light hydrogenation reduced the iodine value of the northern oil from 134 to 120 and the southern oil from 106 to 102. Hydrogenation increased the overall stability of both oils but did not alter the rate of loss of oxidative stability as represented by a plot of the log of the active oxygen method values versus the number of hours the oil had been heated. Non‐gas liquid chromatography eluting material which includes oxidation products, polymers, and unsaponifiables reached a maximum of 4.1%.
