Abstract: In a production method for a protein processed food, a tubular body having an outlet for a protein processed food at one end, and a core material arranged inside the tubular body and extending to at least the outlet along an axial direction of the tubular body are used, a mixture is supplied between the tubular body and the core material while the core material is rotated around the axial direction of the tubular body, the mixture is extruded toward the outlet, and at a side further upstream than the outlet, the mixture is internally heated and coagulated, and the coagulated hollow protein processed food is discharged from the outlet.

Abstract: In the specification, a method for purifying a compound by column chromatography, and a method for optimizing the symmetry factor and theoretical plate number by allowing the slurry to settle and reducing the sedimentation volume of the slurry. A compound purified by such method is also provided.

Abstract: PROBLEM To provide a composition comprising highly enriched PUFA or its alkyl esters while containing fatty acid esters of 3-MCPD at adequately low concentrations and to provide an efficient method for producing the composition. MEANS FOR SOLVING A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is less than 1.80 ppm.

Abstract: The purpose of the present invention is to provide very long chain polyunsaturated fatty acids and/or derivatives thereof. Substance production of very long chain polyunsaturated fatty acids and/or derivatives thereof has been possible by the conventional technology. However, concentrations of the produced substances have been low. The substance production of very long chain polyunsaturated fatty acids and/or derivatives thereof has been possible. However, the substances produced cannot be obtained in sufficient concentrations and cannot be used as compositions. The present invention provides very long chain polyunsaturated fatty acids and/or derivatives thereof with increased concentrations. Moreover, the object of the present invention is to provide a composition comprising very long chain polyunsaturated fatty acids and/or derivatives thereof.

Abstract: A processed meat-like food containing a connective tissue-like texture imparting agent and a textured vegetable protein, and having texture closer to processed meat foods produced from meat as a main raw material; a connective tissue-like texture imparting agent capable of imparting to a processed meat-like food a texture closer to processed meat foods produced from meat as a main raw material; a method for texture improvement of a processed meat-like food containing a textured vegetable protein, where a connective tissue-like texture imparting agent is added, the method approximating the texture of a processed meat-like food to processed meat foods produced from meat as a main raw material; and a production method for a processed meat-like food, including mixing a connective tissue-like texture imparting agent and a textured vegetable protein, the method resulting in a processed meat-like food having texture closer to those of processed meat foods produced from meat.

Abstract: The present invention provides a method of producing a composition containing docosahexaenoic acid as a constituent fatty acid of glycerides. The method includes hydrolyzing a feedstock oil containing glycerides, the glycerides including docosahexaenoic acid as a constituent fatty acid, by action of a first lipase and a second lipase, to increase the proportion of docosahexaenoic acid in glyceride fractions. The first lipase is at least one lipase selected from the group consisting of a lipase obtained from a microorganism of the genus Thermomyces, a lipase obtained from a microorganism of the genus Pseudomonas, a lipase obtained from a microorganism of the genus Burkholderia, and a lipase obtained from a microorganism of the genus Alcaligenes. The second lipase is a partial glyceride lipase.

Abstract: [Problem] To provide a composition for external skin use that has anti-inflammatory and antiallergic activity, and is very safe. [Solution] A composition for external skin use for inflammatory diseases contains dihomo-gamma-linolenic acid (DGLA) as the active ingredient thereof. It is preferable for the DGLA to be present as a glyceride, a phospholipid, or an alkyl ester. The amount of DGLA contained in the composition for external use is 0.1-50 wt %.
