Abstract: Disclosed is a method whereby, in producing a hard butter composition being rich in SUS (2-unsaturated-1,3-disaturated triglyceride) via ester exchange by a 1,3-specific lipase, the production can be more conveniently or more efficiently carried out. In producing a hard butter composition being rich in SUS (2-unsaturated-1,3-disaturated triglyceride) via ester exchange by a 1,3-specific lipase, a low-melting point fraction of allanblackia fat is used as the main starting material, saturated fatty acids are selectively introduced into the 1- and 3-positions of the fat, and then fractionation is optionally conducted to thereby give an SUS-rich fraction.

Abstract: The present invention provides a method of producing water-containing chocolates in which an aqueous component and a fat and oil composition containing tri-saturated fatty acid glyceride crystals dispersed in a fat or oil whose melting point is at or below body temperature are added to and emulsified with a chocolate mass.

Abstract: The present invention aims at providing fat-and-oil compositions which can effectively inhibit the migration of water even when a low-water-content component is in contact with a high-water-content component and foods made by using the same. Namely, a fat-and-oil composition for inhibiting the migration of water in food wherein the fat-and-oil component contains a 1,2-saturated-3-unsaturated glyceride (SSU) in an amount of 15 wt % or above but preferably below 50 wt % and a 1,3-saturated-2-unsaturated glyceride (SUS) in an amount of less than 50 wt %; fat-and-oil compositions as described above which further contain at least one member selected from among mono-diglycerides, sorbitan tristearate, and acetylated sucrose fatty acid esters, or a solid matter other than fats and oils; and foods containing, between low-water-content regions and high-water-content regions, the fat-and-oil compositions for inhibiting the migration of water.

Abstract: A foamed chocolate which can be foamed without resort to any special apparatuses or emulsifiers, has a lightened chocolate texture and shows no oily feel. This foamed chocolate is produced by adding an oil mixture comprising an edible fat or oil with tri-saturated fatty acid glycerides containing behenic acid.

Abstract: 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.

Abstract: Chocolate having excellent hardness and melting properties in the mouth upon eating at a temperature range of freezing or refrigerating is disclosed. The chocolate is subjected to tempering treatment and has a softening point of 15.degree. to 30.degree. C. Its fat ingredient comprises 95 to 40% by weight of fats rich in 2-unsaturated-1,3-disaturated triglycerides (SUS) the main constituent fatty acids of which are palmitic acid (P) and stearic acid (St) with a P/St ratio of at least 1.0 and 5 to 40% by weigh of lauric fats, the relation of P/St ratio of SUS to the fat content in the chocolate being on or in the higher fat content region above line 1 as shown in FIG. 1.

Abstract: A hard butter composition suitable for a cocoa butter substitute which comprises as a main ingredient a triglyceride SUS, constituent saturated fatty acids of which contain at least 4% by weight of one or a plurality of fatty acids selected from the group consisting of behenic acid, lignoceric acid, cerotic acid and arachidic acid, provided that the amount of arachidic acid is less than 4% by weight based on the total weight of the constituent saturated fatty acids.
