<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing tea, which has such an effect as to improve a renal function by keeping the caffeine contained in tea, eliminating unwelcome flavor components, and converting an astringent component into polymer polyphenol thereby stabilizing glycohemoglobin (GHb) being an index in diabetes treatment, the manufactured tea, and food. <P>SOLUTION: Tea made by a conventional method is put in a pressure container, and steam is blown into the pressure container, and it is autoclaved to polymerize catechin being an astringent component, whereby functional green tea rich in polymer polyphenol content can be made. Caffeine is kept without sublimating or being thermally decomposed with pressurization or heating under saturated steam. It is found that this green tea is effective for stabilization of the value of glycohemoglobin (GHb) being an index in diabetes treatment and improvement of renal function, so it is useful for diabetes treatment. Functional food can be made from a material, i.e. aromatic green tea. Autoclaving the tea under coexistence of a calcium carbonate will accelerate the polymerization of catechin being an astringent component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
