Cold-resistant fat compsn. and process for producing same

The objects of the present invention are to provide a fat composition which even in long-term storage at low temperature (in a refrigeration or freezing range), has excellent cold resistance because the fat is inhibited from undergoing crystal growth, and to provide a process for producing the compo...

More Information
Summary:The objects of the present invention are to provide a fat composition which even in long-term storage at low temperature (in a refrigeration or freezing range), has excellent cold resistance because the fat is inhibited from undergoing crystal growth, and to provide a process for producing the composition. The present inventors made intensive studies in order to accomplish the object and, as a result, they have found that a cold-resistant fat composition comprising 0.15 to 4.5% by weight of tri-saturated fatty acid glycerides based on a fat which is in a liquid state at room temperature and has 60% or more of the proportion of polyunsaturated fatty acids in all the unsaturated fatty acids therein, a process for producing the same, and an oil-based food comprising as a main component of its fat component(s) the cold-resistant fat composition can be provided.
