Compared to vegetable oil, vegetable shortening is solid at room temperature, white in color, and much less prone to rancidity as it is a saturated fat. It has essentially an unlimited shelf life.It is also very neutral in flavor, so is often used to grease pans.egetable oil is converted into vegetable shortening by hydrogenating it, forcing hydrogen to bind on to the ends of the fatty acids. This is done by forcing hydrogen to bubble through the oil under pressure, heat, and in the presence of a catalyst.
