Patent ID: 7435441

Claim:
A fat and oil composition comprising an oil phase which comprises one of: (a) a fat and oil (1) containing a triglyceride represented by StEE, wherein St is stearic acid, and E is elaidic acid, at a proportion in which the triglyceride content is 6.7% to 17.5% by weight; or (b) a fat and oil (2) capable of forming compound crystals of: (i) a triglyceride represented by S 1 MS 2 , wherein S 1 and S 2 each is a saturated fatty acid, and M is a mono-unsaturated fatty acid, and/or (ii) a triglyceride represented by MS 3 M, wherein S 3 is a saturated fatty acid, and M is a mono-unsaturated fatty acid, in which the molar ratio of MS 3 M/S 1 M 2 is 0.4 to 2.5 and the proportion of the content of compound crystals is 5% to 42% by weight; wherein, when the oil phase of said fat and oil composition is completely melted at 70° C. and maintained at 0° C. for 30 minutes and then at 5° C. for 7 days, the resulting fat and oil crystals are β form crystals having a double chain length structure.
