た。2. Description of the Related Art Tochu leaf powder is used as Tochu tea and food materials. Tochu leaves are harvested in autumn, dried, cultivated and crushed to obtain Tochu powder. The dried Tochu leaf is brown, and the Tochu powder obtained by crushing it is brown. Conventionally, green tea has been the mainstream of the tea that has been drunk in Japan, and the one with excellent quality is bright green. Therefore, there is an image among consumers that high-quality tea is green,
The brown tea had a low commercial value by itself. Further, it is hard to say that brown as a color of food materials causes a delicious taste as compared with green. Therefore, it has been desired to obtain green Tochu powder to increase the added value as a product.

That is, the green color of plants is due to the chlorophyll existing therein, but the chlorophyll is easily discolored by the loss of magnesium ions due to oxygen, heat and the like. On the other hand, various pigments represented by polyphenols such as anthocyan are contained in the plant, and these pigments turn brown and become brown at the same time as the fading of chlorophyll. Various methods have been tried so far in order to prevent fading of chlorophyll. The best known method is to convert the magnesium ion at the center of chlorophyll cross-linking into a copper ion. However, since copper ions are heavy metals, this method is prohibited by the Food Sanitation Law.

Therefore, they have found that the magnesium ion of the porphyrin ring constituting chlorophyll is easily removed under acidic condition, and the green color of chlorophyll disappears.
That is, the present invention is a method for producing a green eucommia powder characterized by processing the green leaves of Eucommia vulgaris harvested from April to September, and eucommia leaves harvested at such a time under neutral or alkaline conditions. And a step of blanching the green eucalyptus powder.

The green leaves of Tochu in the present invention are harvested from April to September, preferably from May to August, and more preferably from June to early August. Conventionally, Tochu leaves are 1
It had been harvested since late October. However, even if it is initially green, the Tochu leaves harvested after the end of October are likely to be discolored during the processing step, storage period or when used as food. Contrary to the conventional wisdom, the present inventor succeeded in producing Tochu powder having a stable green color by harvesting Tochu leaves before September.
It is desirable to process the green leaves of Tochu that are harvested from April to September immediately, but if it is necessary to store the harvested Tochu green leaves without processing, refrigerate or freeze store at 0 ° C or below. Well, preferably frozen and stored at -15 to -20 ° C.

The pH is preferably 6 or more, more preferably 7 to 13. It is speculated that branching under such conditions may deactivate the enzymes involved in fading in the Tochu leaf and maintain the green color.
The blanching temperature is preferably 60 to 100 ° C, more preferably 70 to 100 ° C. The time is preferably 1 to 10 minutes, more preferably 1 to 3 minutes. However, the blanching temperature and time are correlated, and the time may be short when the temperature is high, and the time needs to be long when the temperature is low. For example, it may be 1 minute at 100 ° C, but is preferably 3 minutes or more at 70 ° C.

The lining solution was concentrated under reduced pressure, and SD-20 (a mixture of 20% by weight of cyclodextrin and 80% by weight of dextrin) manufactured by Shimizu Minato Sugar Co., Ltd. was added in an amount equal to the dry weight of boiled leaves and freeze-dried.
Tochu powder was manufactured. Separately, another Tochu powder was produced in the same manner except that SD-20 was not added. These Tochu powders were irradiated at 28,500 lux with a light beam spoiler and the degree of fading was measured. Irradiation for 45 hours with this amount of light is equivalent to exposure to a room on a sunny day for 2.7 consecutive months. Table 4 shows the degree of fading when the initial green color was set to 100. S
It was found that the addition of D-20 suppressed the fading after 47 hours.
