Abstract: The present invention provides a method for producing a purified lipase which comprises steps of: (a) bringing a long chain fatty acid triglyceride and a medium-chain triglyceride into contact with a lipase to purify the lipase; and (b) collecting the purified lipase. According to this production method, the purified lipase can be obtained wherein content of impurity such as silicon is decreased.

Abstract: There is provided a lipase powder which is a granulated material comprising a lipase and at least one member selected from the group consisting of fatty acids having 8 to 12 carbon atoms, alcohol esters thereof, and a mixture thereof. This lipase powder has an increased lipase activity.

Abstract: A method for producing symmetric triglycerides, which comprises the steps of reacting a medium chain fatty acid triglyceride with a long chain fatty acid triglyceride in the presence of an enzyme or a chemical catalyst to conduct random transesterification reaction and thereby to obtain a reaction product containing a triglyceride composed of a medium chain fatty acid and a long chain fatty acid as the constituting fatty acids in the step of the first reaction; transesterifying the reaction product with an alcohol monoester of the medium chain fatty acid in the presence of an sn-1,3-position specific enzyme in the step of the second reaction and then taking the alcohol monoester of the medium chain fatty acid and the alcohol monoester of the long chain fatty acid from the reaction product obtained in the step of the second reaction to obtain the symmetric triglyceride composed of the medium chain fatty acids at the sn-1, 3 positions and the long chain fatty acid at the sn-2 position.

Abstract: An edible fat/oil composition containing a plant sterol, which permits suppressing the deposition of the plant sterol during, for example, the storage and which produces the effect of, for example, inhibiting the absorption of cholesterol, contains an edible fat/oil, linolenic acid in an amount of 1 mass % or more, a plant sterol in an amount of 1 mass % to 10 mass %, tocopherol in an amount of 0.01 mass % to 1 mass %, and a lipophilic emulsifying agent in an amount of 0.005 mass % to 10 mass %.

Abstract: A method for producing a lipase powder, which comprises the step of spray drying an aqueous solution containing a lipase adjusted to pH 6 to 7.5; the lipase powder which is a 1,3-specific lipase derived from Rhizomucor miehei, spherical, and contains not more than 10% by weight of moisture; and a lipase composition wherein the lipase powder is immersed or impregnated in fatty oil. According to the present invention, a lipase powder of which 1,3-selectivity is improved can be provided.

Abstract: An oil and fat composition exhibiting an antifoaming effect, which comprises: (i) at least 50% by mass of triglycerides comprising fatty acids, wherein the fatty acids comprise fatty acids having 6 to 12 carbon atoms and fatty acids having 14 to 22 carbon atoms in a mass ratio of 5:95 to 95:5; and (ii) 0.01 to 10% by mass of one or more polyglycerol fatty acid ester having an average degree of polymerization of 6 to 10 and an average degree of substitution of 4 to 32, wherein the unsaturated fatty acid content of fatty acids constituting the polyglycerol fatty acid ester is 50 to 100% by mass based on the total fatty acids constituting the polyglycerol fatty acid ester.
