Abstract: The purpose of the present invention is to provide a body taste improver comprising a small amount of fat and oil, but significantly showing body taste, i.e., a body taste improver with a high titer. The high titer of the improver will reduce an amount of the fat and oil to be added and calorie as well, and will enable to use the body taste improver in foods that originally contain little fat and oil, such as Japanese-style clear soup and soybean soup. Thus, the present invention is related to a body taste improver comprising decomposed substances of a long-chain highly unsaturated fatty acid and/or an ester thereof, to a body taste improver comprising an extract of decomposed substances of a long-chain highly unsaturated fatty acid and/or an ester thereof, and to a food comprising said body taste improver.

Abstract: The purpose of the present invention is to provide fat and oil being free of cholesterol and having a low content of saturated fatty acid, while having body taste. Thus, the present invention is related to a body taste improver comprising a long-chain highly unsaturated fatty acid and/or an ester thereof, especially one for vegetable fat and oil, and to a vegetable fat and oil composition comprising the body taste improver.

Abstract: The purpose of the invention is to enhance the body taste, taste and flavor of foods. Thus, the present invention is related to a method for enhancing or making better body taste or taste of the foods by adding n-3 long-chain highly unsaturated fatty acid having 20 or more of carbon atoms and 3 or more of double bonds, or adding n-6 long-chain highly unsaturated fatty acid having 18 or more of carbon atoms and 3 or more of double bonds to them.

Abstract: The purpose of the present invention is to provide a fat or oil composition that can be protected from the off-flavor of the fish oil for a long period of time, and can be used in usual cooking without any problems. Thus, the present invention is related to a fat or oil composition comprising oleic acid of 3˜9 parts by weight, preferably 3˜7 parts by weight, linolic acid of 5˜15 parts by weight, preferably 6˜10 parts by weight and linolenic acid of 0.1˜1.5 parts by weight, preferably 0.5˜1.5 parts by weight per one part by weight of long-chain highly unsaturated fatty acids, and to a fat or oil composition comprising oleic acid of 5˜40 parts by weight, preferably 8˜35 parts by weight, linolic acid of 10˜60 parts by weight, preferably 12˜45 parts by weight and linolenic acid of 0.1˜4 parts by weight, preferably 0.2˜3 parts by weight per one part by weight of long-chain highly unsaturated fatty acids.

Abstract: The purpose of the invention is to provide a means for improving the body taste, taste and flavor of foods.

Abstract: A process for modifying fats and oils which comprises applying partial glyceride lipase to fats and oils containing partial glycerides and fatty acids to synthesize triglycerides from the partial glycerides by esterification.The lipase is preferably an immobilized lipase and this process is preferably carried out under a water concentration of 1500 ppm or less.By using partial glyceride lipase according to the present invention, there can be obtained modified fats and oils having a low content of diglycerides without changing triglyceride composition.

Abstract: The present invention relates to a method for reforming fats and oils which comprises treating the fats and oils containing partial glycerides with two or more kinds of lipases which are different in a fatty acid specificity and/or a position specificity in the presence of a small amount of water to obtain fats and oils containing partial glycerides in a low content in a high yield. According to the invention, a reaction rate and a yield are improved.

Abstract: A process of extracting vegetable oil and fat from an oleaginous raw material which comprises the steps of obtaining flakes having a moisture content of from 0.7 to 10 weight % from an oleaginous raw material; contacting the flakes with an ethanol solution containing not less than 90 weight % ethanol at a temperature in the range of from 70.degree. C. to the boiling point of the ethanol solution, thereby obtaining a miscella; cooling the miscella, thereby obtaining vegetable oil or fat and a separate defatted miscella; drying the defatted miscella with a molecular sieve material having a pore size of from 3 .ANG. to 4 .ANG., thereby obtaining a second ethanol solution wherein the second ethanol contains less than 7 weight % water; and using the ethanol solution obtained in the drying step as the ethanol solution of the contacting step in a second extraction.
