A method for producing a polyphenol composition including a step of subjecting (A) a hardly water-soluble polyphenol and (B) one or more selected from cathechins, chlorogenic acids and methylated compounds of hardly water-soluble polyphenols to a heat treatment at from 100 to 180&#xb0; C. in the presence of an aqueous medium.

Manufacturing method for polyphenol composition

The present invention relates to a process for producing a fatty acid, which includes feeding a liquid mixture formed of two liquid phases that flow in a co-current manner into a fixed bed-type reaction column packed with immobilized lipase, and performing a hydrolysis reaction when the two liquid phases are in contact with the immobilized lipase in the fixed-bed reaction column; wherein the fixed-bed reaction column comprises partition plates so as to comprise a plurality of tube- shaped structures, wherein each tube-shaped structure has a cross -section which is rectangular, circular, oval, or polygonal in shape with at least a part being unclosed and the cross-section has a representative length of 100 mm or less.

Process for producing useful substance with immobilized enzyme

The present invention relates to a process for producing a useful substance, the process includes feeding a liquid mixture formed of two liquid phases into a fixed bed-type reaction column packed with an immobilized enzyme, and allowing the liquid mixture to flow in the same direction in a co-current manner to perform a reaction. The packing thickness of the immobilized enzyme per stage of the fixed bed-type reaction column having an equivalent circular diameter of 35 mm&#x3c6; or larger is 10 to 200 mm. The flow of the reaction liquid inside the column can be made uniform, and as a result, reactivity and productivity is enhanced.
