PROBLEM TO BE SOLVED: To provide a fractional modifier for an oil-and-fat, which is added to an oil-and-fat as a fractional object, for example, palm oil, to enable an improvement in a yield of a liquid fraction therein, in the case where the oil-and-fat which is a mixture of solid components and liquid components at ordinary temperature is fractionated into its liquid fraction and solid fraction by a natural fractionation method carried out under usual conditions.SOLUTION: The fractional modifier for an oil-and-fat comprises a diglycerol aliphatic acid ester using as a main constituting aliphatic acid a mixed aliphatic acid of two or more selected from 8-22C aliphatic acids, especially 12-18C aliphatic acids. |
