Abstract
There is disclosed a process for improving a glycerolyzed oil. The oil is heated until any crystals which have formed have disappeared. Then the oil is crystallized by slow stirring for eight to seventy-two hours until an end of crystallization temperature of typically between 0.degree. and 15.degree. is reached. Finally the crystals which have formed are separated at the end of crystallization temperature. The process can be iterated at two successively lower end of crystallization temperatures.
