<P>PROBLEM TO BE SOLVED: To utilize condensed extract of reaped and discarded tea leaves, which are abundant and which are said to have nearly 30% content of catechins, as raw materials, because catechins extracted by heat-treating tea leaves, though it is preferable to utilize catechins extracted by heat-treating tea leaves, are likely to be oxidized in contact with air or adversely affected by light or heat, and therefore, there is difficulty in processing; and to provide a method for deodorization. <P>SOLUTION: (1) Roasted tea can be produced by roasting tea leaves which can be roasted. By further roasting the roasted tea, an organic substance is produced on the way from the roasted tea till the carbonization. The produced substance is called roasted tea, which can be utilized. (2) The roasted tea has such a characteristic that the deodorization effect is enhanced by heating the roasted tea, and the characteristic can be utilized. The same deodorization effect can be obtained by heating tea leaves for deodorization with the tea leaves, but it is necessary to pass through a range or region of the roasted tea to achieve the result. The same result can not be achieved without passing through the same route as roasting by heating. Particularly, tea and garlic are natural products inherited from old times, and useful crops for the humankind. Either product has a high medication effect, and particularly, the condensed extract from roasted tea is as high effect as garlic. From the view-point of preventive medicine, the condensed extract of roasted tea is useful for people's health maintenance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
