<P>PROBLEM TO BE SOLVED: To provide a method for producing a non-polymeric catechin composition purification-treated for removing a fragrant aroma peculiar to a pot-roasted tea produced by excessive heating and also improving the hue and flavor of the non-polymeric catechin composition in performing the purification treatment of the non-polymeric catechins in a water-soluble composition extracted by using water from green tea leaves produced by the pot-roasting production method. <P>SOLUTION: This method for producing the non-polymeric catechin composition is provided by adsorbing the water-soluble composition extracted by using water from the green tea leaves produced by the pot-roasting production method with a column filled with a synthetic adsorbent by 0.5-20 [v/v] liquid passing multiple based on the synthetic adsorbent, washing with with water by 1-10 [v/v] liquid passing multiple based on the synthetic adsorbent, and then eluting by passing through 0.5-20 [v/v] amount of 10-95 vol% aqueous ethanol solution based on the filled volume amount of the synthetic adsorbent. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
