Abstract
Abstract A hard butter having an iodine value of 52 to 75, a melting point of 30 DEG to 40 DEG C. and a trans-isomer content of at least 40% by weight based on the total weight of combined fatty acids and consisting essentially of (a) 50 to 100% by weight of a first hardened oil obtained by hydrogenating with isomerization a rice-bran oil having an iodine value of 97 to 108, a C16 saturated acid content of 15 to 22% by weight based on the total weight of combined fatty acids and 1.0 to 4.0% by weight, based on the rice bran oil, of higher alcohol fatty acid esters of which the combined higher alcohols are unsaponifiable and/or a fraction obtained by fractionation of the first hardened oil and (b) 50 to 0% by weight of a second hardened oil obtained by hydrogenating with isomerization a vegetable oil substantially free of trisaturated glycerides and having C16 saturated fatty acid content of 12 to 30% by weight and a C18 di-unsaturated acid content of 30 to 55% by weight based on the total weight of combined fatty acids and/or a fraction obtained by fractionation of the second hardened oil.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
253 words
A hard butter having an iodine value of 52 to 75, a melting point of 30° to 40° C., a C 16 saturated fatty acid content of 10 to 30% by weight, a C 18 saturated fatty acid content of 2 to 10% by weight, a C 18 mono-unsaturated fatty acid content of 55 to 75% by weight and a trans-isomer content of 40 to 70% by weight based on the total weight of combined fatty acids, said hard butter consisting essentially of (a) 50 to 100% by weight of a first hardened oil obtained by hydrogenating with isomerization a rice bran oil having an iodine value of 97 to 108 and a C 16 saturated acid content of 15 to 22% by weight based on the total weight of combined fatty acids and containing 1.0 to 4.0% by weight, based on the rice bran oil, of higher alcohol fatty acid esters of which the higher alcohols are unsaponifiable matters of said rice bran oil, a fraction obtained by fractionation of the first hardened oil, or mixture thereof, and (b) 50 to 0% by weight of a second hardened oil obtained by hydrogenating with isomerization a vegetable oil substantially free of tri-saturated glycerides and having a C 16 saturated fatty acid content of 12 to 30% by weight and a C 18 diunsaturated acid content of 30 to 55% by weight based on the total weight of combined fatty acids, a fraction obtained by fractionation of the second hardened oil, or mixture thereof.
Claim 2
Dependent Claim
253 words
A hard butter having an iodine value of 52 to 75, a melting point of 30° to 40° C., a C 16 saturated fatty acid content of 10 to 30% by weight, a C 18 saturated fatty acid content of 2 to 10% by weight, a C 18 mono-unsaturated fatty acid content of 55 to 75% by weight and a trans-isomer content of 40 to 70% by weight based on the total weight of combined fatty acids, said hard butter consisting essentially of (a) 50 to 100% by weight of a first hardened oil obtained by hydrogenating with isomerization a rice bran oil having an iodine value of 97 to 108 and a C 16 saturated acid content of 15 to 22% by weight based on the total weight of combined fatty acids and containing 1.0 to 4.0% by weight, based on the rice bran oil, of higher alcohol fatty acid esters of which the higher alcohols are unsaponifiable matters of said rice bran oil, a fraction obtained by fractionation of the first hardened oil, or mixture thereof, and (b) 50 to 0% by weight of a second hardened oil obtained by hydrogenating with isomerization a vegetable oil substantially free of tri-saturated glycerides and having a C 16 saturated fatty acid content of 12 to 30% by weight and a C 18 diunsaturated acid content of 30 to 55% by weight based on the total weight of combined fatty acids, a fraction obtained by fractionation of the second hardened oil, or mixture thereof.
Claim 3
Dependent Claim
39 words
A hard butter according to claim 1 wherein said hard butter consists essentially of said first hardened oil obtained by hydrogenating with isomerization of the rice bran oil or the fraction obtained by fractionation of said first hardened oil.
Claim 4
Dependent Claim
