A novel, chemically-modified partially hydrogenated vegetable oil (PHVO) is described. The PHVO is produced by a three-step reaction process that includes epoxidation, a ringopening reaction, followed by esterification. The modified PHVO has improved kneadability and, if mixed with fully hydrogenated fat(s ), hardness comparable to umnodified PHVO.
