<P>PROBLEM TO BE SOLVED: To provide a fractionation method for fats and oils whereby fats and oils containing a large amount of asymmetric triglycerides (SSO) can be efficiently fractionated and the resultant crystal section and liquid section can be utilized for margarine, etc. <P>SOLUTION: This fractionation method for fats and oils is characterized in that fats and oils of which the crystal form after completely melted at 70°C or higher, kept at 0°C for 30 min, and kept at 5°C for 7 days is a β-type crystal with a two-chain length structure are fractionated into a crystal section and a liquid section. <P>COPYRIGHT: (C)2003,JPO |
