Method for fractionating an oil or fat to separate the high melting point components thereof

摘要

A method is provided for fractionating an oil to separate high melting components thereof, which comprises the steps of: (a) adjusting the temperature of an oil or fat to a temperature from the complete melting point to thirty Celsius degrees above the slip melting point of the oil or fat; (b) seeding the temperature-adjusted oil or fat with seed crystals of the high melting point components of said oil or fat; (c) cooling said seeded oil or fat below said temperature to crystallize said high melting point components; and (d) separating the crystals of said high melting point components from the slurry obtained in step (c).
