Provided is a powdered green tea extract composition, including the following components (A) to (C): (A) non-polymer catechins; (B) quinic acid; and (C) a polysaccharide, wherein the powdered green tea extract composition has a volatile content of 5.6 mass % or less, wherein a mass ratio between the component (A) and the component (B), [(B)/(A)], is less than 0.2, wherein amass ratio between the component (A) and the component (C), [(C)/(A)], is 1.2 or more, wherein, when an absolute value (Δa*) of a difference between an a* value in an L*a*b* color system of the powdered green tea extract composition after storage under an atmosphere of 37° C. and 50% RH for 6 weeks and an a* value in the L*a*b* color system of the powdered green tea extract composition immediately after production is obtained, the Δa* of the powdered green tea extract composition is a value less than Δa* of a powdered green tea extract composition α which has the same mass ratio [(B)/(A)] as the mass ratio [(B)/(A)] of the powdered green tea extract composition, and which is free of the component (C), and wherein a change rate calculated by the following expression (2) is 5% or more: (Δa*−Δa*)/Δa*×100 (2) where Δa* and Δa* have the same meaning as Δa* and Δa* described in Description.

Powdered green tea extract composition

The present invention provides a method for producing a useful substance by supplying, to a fixed-bed reactor packed with an immobilized enzyme, a liquid mixture containing two liquid phases, in which the two liquid phases are allowed to flow in an identical, parallel direction, which method employs a fixed-bed reactor equipped with an insertion unit or tubes, so as to form a plurality of lumens in the fixed-bed reactor, each lumen having a cross section of a circular shape with a diameter of 100 mm or less or having a polygonal shape with a diagonal line of 100 mm or less, wherein the lumens are packed with an immobilized enzyme and the liquid mixture is supplied. In a reaction performed by passing a reaction mixture exhibiting two liquid phases through a fixed-bed reactor equipped with an immobilized enzyme, overall flow of the reaction liquid is made uniform.

Method for producing a useful substance by use of an immobilized enzyme

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

A process for producing fatty acids, which comprises supplying an oil phase substrate and a water phase substrate to an enzyme column packed with an immobilized enzyme, concurrently flowing them in the same direction, and hydrolyzing a fat and/or oil, wherein the oil phase substrate and the water phase substrate are alternately supplied to the enzyme column.

Method for producing fatty acids with an immobilized enzyme packed column

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.

Process for producing useful substance using immobilized enzyme

To provide a packaged high-catechin beverage in which a low-caffeine green tea extract is added. A packaged beverage containing from 0.03 to 1.0 wt % of non-polymer catechins, in which a low-caffeine green tea extract obtained by a method of brining a green tea extract into contact with a 91/9 to 97/3 by weight mixture of an organic solvent and water, activated carbon, and acid clay or activated clay is added.

A method for producing detergent granules, includes the step of dry-neutralizing a liquid acid precursor of a non-soap, anionic surfactant with a water-soluble, solid, alkali inorganic substance. In this method, a dry-neutralizing step is carried out in the presence of 0.1 to 1.0 mol of an inorganic acid per mol of the liquid acid precursor of a non-soap, anionic surfactant. The above detergent granules have the features of extremely low tackiness of the granules and containing larger number of micropores. By using the detergent granules, a high-bulk density detergent composition having a small particle size can be obtained at high yields.
