For example, in the past, so-called gabalon tea has been known in which tea leaves that have been plucked are placed under anaerobic conditions in the process of manufacturing tea to accumulate GABA in large amounts in the tea leaves. Japanese Patent Laid-Open No. 8-
Japanese Patent No. 173111 describes that coffee leaf tea having a high GABA concentration is obtained by a method in which fresh coffee leaves are treated in an oxygen-free state, and then heat-treated and dried at a high temperature of 110 ° C. or higher. Further, Japanese Patent Application Laid-Open No. 9-205989 discloses that tea leaves are irradiated with infrared rays to improve the GABA content.

ＡＢＡも減少する傾向にある。The microwave treatment may be carried out within a range in which the enzyme involved in fading of the green leaves of grasses is inactivated or the green color is not lost by heating. Such a range can be appropriately adjusted by the output of the microwave irradiation device, the wavelength of the microwave, the irradiation time, and the like. For example, 100 g of green leaf (young leaf) of rice that was cut at a height of about 30 cm
When a microwave of 2450 MHz and 500 W is applied per (wet weight), the treatment is performed for 0.5 to 10 minutes, preferably 0.5 to 5 minutes, and more preferably 0.5 to 1 minute. If it is less than 0.5 minutes, inactivation of the enzyme is insufficient and fading easily occurs. Also, if it is treated for 10 minutes or more, it will fade and G
ABA also tends to decrease.

Drying is carried out at a temperature as low as possible, for example, 50 to 80 ° C., preferably 55 to 55 so that the treated green leaves do not become discolored.
Perform at 65 ° C. In addition, you may perform the said process and drying simultaneously in parallel.
