Abstract:
1. A method of partially hydrogenating an unsaturated fat, comprising: dispersing a nickel-based catalyst in an unsaturated edible oil, the edible oil having an initial Iodine Value and an initial fatty acid profile; delivering hydrogen to the oil; and hydrogenating the oil at a hydrogenation temperature no greater than about 75° C. for a hydrogenation time to yield a partially hydrogenated fat having a modified Iodine Value and including a modified fatty acid profile, wherein the partially hydrogenated fat has a solid fat content of about 25-80 weight percent at 20° C., an absolute difference between the initial Iodine Value and the modified Iodine Value (dIV) divided by the hydrogenation time defines an average Iodine Value change rate of no less than about 5/hour, and no more than about 15 weight percent of the modified fatty acid profile comprises trans-fatty acids.
