Abstract: A two-step reaction method for the transesterification of fats and oils, comprising hydrolyzing fats and oils to produce diglycerides by reacting said fats or oils with lipase; esterifying said digylcerides and to produce triglycerides by reacting said diglycerides with at least one fatty acid.

Abstract: A hard butter of the present invention is obtained by adding 0.05 to 20% by weight of polyglycerol fatty acid ester(s), which is prepared by binding four or more moles in average of fatty acid(s) to polyglycerol(s) having five or more in average of hydroxyl groups, to a hard butter. With the use of the hard butter of the present invention, the anti-blooming properties of a chocolate are enhanced with little limitation on the composition of the same. In particular, chocolates containing trans and lauric hard butters can be more freely compounded thereby than in the case of conventional ones.

Abstract: The hard butter of the present invention comprises a fat which is obtained from the pericarp of the Chinese tallow tree by extraction optionally followed by fractionation and has a solid fat content of 80% or more, 60% or more and 0.5% or less at 20.degree. C., 30.degree. C. and 40.degree. C., respectively. And the other hard butter of the present invention comprises 5 to 95% of the pericarp oil as defined above and 95 to 5% by weight of one or more fats selected from among, for example, sal fat, fractionated sal fat, fractionated shea fat, kokum fat, mango kernel fat, fractionated mango kernel fat and illipe fat.

Abstract: A cacao butter substitute is disclosed having a medium melting point fraction of palm oil, having a solid fat content of 70% or more at 20.degree. C., 10% or more at 30.degree. C., 1% or less at 33.degree. C. and 0% at 35.degree. C., and showing an initial curve in cooling curve which is identical down to 19.degree. C. to the initial curve of a palm soft oil having an iodine value of 65 or above in which the medium melting point fraction is removed and the high melting point fraction is completely removed. The cacao butter substitute has very sharp melting characteristics and excellent compatibility with cacao fat.

Abstract: A cacao butter substitute comprising a triglyceride composition wherein the saturated fatty acid radicals comprise substantially palmitic acid radical, stearic acid radical and arachidic acid radical and the molar proportion of the arachidic acid radical to the total saturated fatty acid radicals is 4 to 15 molar % and that of the palmitic acid radicals is 10 to 65 molar % and that of the stearic acid radicals is 20 to 86 molar %; the unsaturated fatty acid radicals comprise substantially oleic acid radical and linoleic acid radical and the molar proportion of linoleic acid radical to the total unsaturated fatty acid radicals is less than 20 molar %; and the proportions of the glycerides are as follows, based on the total triglyceride components: 1 to 5 molar % of trisaturated triglycerides, 50 to 80 molar % of .beta.-unsaturated-.alpha.,.alpha.'-disaturated triglycerides, less than 5 molar % of .alpha.- or .alpha.'-unsaturated-disaturated triglycerides, 15 to 50 molar % .alpha.- or .alpha.

Abstract: A hard butter having an iodine value of 52 to 75, a melting point of 30.degree. to 40.degree. 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 C.sub.16 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 C.sub.16 saturated fatty acid content of 12 to 30% by weight and a C.sub.

Abstract: A cocoa butter substitute comprises sal fat obtained by extracting the fat from the seeds of Shorea robusta and then refining the resulting product. The cocoa butter substitute has a hydroxy value of not more than 16, a solid fat index of not less than 48 at 30.degree. C., a cooling time, at which the maximum point appears in the cooling curve, of not longer than 120 mins. and the maximum point temperature of not less than 17.degree. C.

Abstract: A hard butter is prepared from a selective hydrogenation-isomerization product of a palm olein and a vegetable oil or fat other than palm oil.
