PROBLEM TO BE SOLVED: To provide a method of processing tea leaves for increasing various kinds of nutrition values contained in the tea leaves. SOLUTION: A tea leaves containing prescribed moisture is heat-treated by superheated steam, and then is passed through a strainer for crushing processing. In this manner, tea leaves containing moisture is heat-treated by superheated steam so that the moisture does not dry, thus increasing a glutamic acid and polyphenol, namely nutritive values contained in the tea leaves. A puree-like, or paste-like tea-leaf processed product, where the tea leaves are passed through the strainer without being dried for crushing processing, can be used directly to drink only by thinning with hot water, can be used for food directly, and also can be used for direct addition to confectionery, or the like. Then, preservative quality is extremely satisfactory, and need for addition of an antioxidant, or the like is reduced. COPYRIGHT: (C)2012,JPO&INPIT |
