Abstract
Abstract A mixed acid triglyceride inhibits a hard butter from fat-blooming, having as the main acid moiety 15 to 70 wt. % of saturated fatty acids having 20 to 24 carbon atoms and 20 to 60 wt. % of unsaturated fatty acids having 16 to 22 carbon atoms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A fat blooming inhibitor comprising a mixture of triglycerides, said mixture containing from 40 to 100 percent by weight of a mixed-acid, triglyceride component, said triglyceride component containing, in the same molecule as different fatty acid moieties, both saturated fatty acids having 20 to 24 carbon atoms and unsaturated fatty acids having from 16 to 22 carbon atoms, the amount of said saturated fatty acids in said mixture being from 15 to 70 percent by weight and the amount of said unsaturated fatty acids in said mixture being from 20 to 60 percent by weight, both percentages being based on the total weight of the fatty acid moieties present in said mixture.
Claim 2
Dependent Claim
112 words
A fat blooming inhibitor comprising a mixture of triglycerides, said mixture containing from 40 to 100 percent by weight of a mixed-acid, triglyceride component, said triglyceride component containing, in the same molecule as different fatty acid moieties, both saturated fatty acids having 20 to 24 carbon atoms and unsaturated fatty acids having from 16 to 22 carbon atoms, the amount of said saturated fatty acids in said mixture being from 15 to 70 percent by weight and the amount of said unsaturated fatty acids in said mixture being from 20 to 60 percent by weight, both percentages being based on the total weight of the fatty acid moieties present in said mixture.
Claim 3
Dependent Claim
28 words
A fat blooming inhibitor as claimed in claim 1 in which said mixture of triglycerides contains from 50 to 100 percent by weight of said mixed-acid, triglyceride component.
Claim 4
Dependent Claim
50 words
A fat blooming inhibitor as claimed in claim 1 in which said saturated fatty acid in said mixed-acid, triglyceride is at least one of arachic acid and behenic acid and said unsaturated fatty acid in said mixed-acid, triglyceride is at least one of oleic acid, linoleic acid and linolenic acid.
Claim 5
Dependent Claim
71 words
A fat blooming inhibitor as claimed in claim 1 wherein said mixed-acid, triglyceride component is prepared by interesterifying a fatty acid triglyceride containing at least 30 percent by weight of saturated fatty acids having 20 to 24 carbon atoms, with a vegetable oil containing at least 60 percent by weight of unsaturated fatty acids having 16 to 22 carbon atoms, and recovering said fat blooming inhibitor from the interesterification reaction product.
Claim 6
Dependent Claim
76 words
A fat blooming inhibitor as claimed in claim 1 wherein said mixed-acid, triglyceride component is prepared by subjecting vegetable oil containing at least 60 percent by weight of unsaturated fatty acid having 16 to 22 carbon atoms at the β-position of the triglyceride nucleus, and saturated fatty acid having 20 to 24 carbon atoms to an enzymatic selective interesterification, removing fatty acids from the reaction product and recovering said fat blooming inhibitor from the reaction product.
Claim 7
Dependent Claim
97 words
A fat blooming inhibitor as claimed in claim 1, which consists essentially of up to 5.0% of PPU triglyceride, from 0.5 to 20.4% of PSU triglyceride, from 2.4 to 24.7% of SSU triglyceride, from 7.2 to 14.7% of ASU triglyceride, from 24.6 to 34.7% of AAU and BSU triglycerides, from 2.0 to 12.2% of ABU triglyceride, from 6.8 to 47.5% of BBU triglyceride, and from 0.2 to 2.6% of BBA triglyceride, wherein P represents palmitic acid, S represents stearic acid, U represents unsaturated acids having 18 carbon atoms, A represents arachic acid and B represents behenic acid.
Claim 8
Dependent Claim
24 words
A hard butter composition which comprises a hard butter and 0.5 to 30 wt.% of the fat blooming inhibitor as defined in claim 1.
