METHOD FOR PRODUCING GREEN AND DRIED EUCOMMIA LEAF PRODUCT

摘要

The purpose of the present invention is to provide a processing method, whereby a green tea micropowder having a pure green color and high sweetness and containing a large amount of useful components can be produced while shortening the production time by 1/4 (compared with a conventional method requiring 120 minutes) and minimizing the heating of leaves in drying and milling, and a green micropowder produced by the processing method. A method for heating and drying fresh eucommia leaves by far infrared ray irradiation, said method comprising: irradiating fresh eucommia leaves with far infrared ray under blowing an air stream at 0-60^oC thereto from start to finish of the heating and drying treatment; and thus conducting the heating and drying treatment in such a manner that the moisture content of the leaves is reduced to 3% or less, relative to the moisture content thereof prior to drying, within 30 minutes after starting the heating, thereby giving a green and dried eucommia leaf product.
