Abstract: A method for producing a microbial microcapsule, including, mixing a (A) hydrophobic component having a surface tension above 33.6 mN/m at 25° C. and a microorganism (B) for 3 hours or more. The mixing is carried out under a condition that a mass ratio of the (A) hydrophobic component to a dry mass of the microorganism (B), [(A)/(B)], is above 2.

Abstract: A method for manufacturing a fermentation product by culturing a microorganism, the method containing steps (A) to (D): (A) culturing the microorganism with a first culture medium; (B) passing a culture solution containing cultured bacterial cells, raw materials for culture, and the fermentation product through an adsorption tower packed with an adsorbent capable of adsorbing the fermentation product from the culture solution, and then collecting an effluent containing the bacterial cells and the raw materials for culture flowing out from the adsorption tower, wherein a relationship among a size (short diameter) d of the bacterial cell, a pore size D1 of the adsorbent, and a minimum void size D2 between adsorbent particles, D1<d<D2 is satisfied; (C) eluting the fermentation product from the absorbent; and (D) culturing the microorganism with a second culture medium using collected effluent containing the bacterial cells and the raw materials for culture.

Abstract: To provide a method for efficiently utilizing bacterial cells and unused raw materials for culture in the manufacture of fermentation products.

Abstract: Provided is a process for producing a tea extract having a high recovery rate of non-polymer catechins, a low caffeine content and an improved taste and color tone. As one embodiment of this invention provides, there is provided a process for producing a purified tea extract by adsorbing a tea extract on a synthetic adsorbent, bringing an aqueous solution of an organic solvent or a basic aqueous solution into contact with the synthetic adsorbent to elute non-polymer catechins, and then bringing the eluate into contact with activated carbon in an aqueous solution of an organic solvent.

Abstract: Provided is a production method for a purified tea extract having improved solubility of the non-polymer catechins in a solvent. The production method for a purified tea extract according to the present invention comprises bringing a tea extract into contact with a magnesium-type or lithium-type cation exchange resin.

Abstract: Provided is a production method for a purified tea extract, which enables efficiently removing gallic acid and collecting the non-polymer catechins in a high yield without impairing original taste and flavor of tea. The production method for a purified tea extract according to the present invention comprises bringing a tea extract into contact with an OH-type anion exchange resin and an H-type cation exchange resin.

Abstract: Provided is a method for producing a purified tea extract, which can satisfy both the yield of the non-polymer catechins and the removal rate of gallic acid at high levels. The method is characterized in that a tea extract, which contains an aqueous solution of an organic solvent, brought into contact with an anion exchange resin.

Abstract: This invention relates to a process for producing a tea extract. The process includes subjecting a first tea extract solution, which has been obtained from tea, to solid-liquid separation so that a turbidity becomes 200 NTU or lower when a concentration of non-polymer catechins is adjusted to 1 wt %, thereby obtaining a second tea extract solution in which a concentration of (A) non-polymer catechins is from 0.2 to 5 wt % and a concentration of non-polymer catechins in solid content is from 15 to 80 wt %; and then subjecting the second tea extract solution to a heat treatment at a temperature of from 95 to 140° C. for an F value of from 0.05 to 40 min.

Abstract: A purified tea extract with suppressed bitterness and astringency is economically produced in high yield and high efficiency by dramatically accelerating an enzyme reaction with addition of tannase in a smaller amount. A process of the present invention for the production of a purified tea extract includes a first step which comprises eliminating water-insoluble solids from a first tea extract and then obtaining a second tea extract so that a turbidity falls into a range from 0.1 to 100 NTU when a concentration of the non-polymer catechins is adjusted to 0.7 wt %, and a second step which comprises subjecting the second tea extract at a concentration of the non-polymer catechins of from 0.05 to 4.0 wt % to tannase treatment.
