COLD-RESISTANT OIL OR FAT COMPOSITION

摘要

PURPOSE: To obtain a cold-resistant oil or fat composition which does not solidify or hardly solidifies even at a temperature as low as about -20 deg.C and is greatly improved in freeze resistance by blending a vegetable oil that is liquid at ordinary temperature with a cane sugar ester of a fatty acid having a specified composition. CONSTITUTION: A cold-resistant oil or fat composition obtained by blending an oil or fat (A) containing at most 10wt.% fat that is solid at 10 deg.C with a cane sugar ester (B) of a fatty acid, wherein the content of the component B is 0.01-5wt.%, the fatty acid that forms the component B comprises a mixture of an 8-22C saturated fatty acid and a 16-22C unsaturated fatty acid at a weight ratio of (80:20) to (20:80), and the component B has an HLB of at most 3. An example of preferable component A is one composed mainly of a castor oil, a rapeseed oil or a macadamia oil. An example of preferable component B is a cane sugar ester of a fatty and wherein the total of the saturated fatty acid and the unsaturated fatty acid accounts for at least 95wt.% of all the fatty acids of the component B.
