Embodiment Construction

[0021] Chuzhou City, Anhui Province is located in the Jianghuai River Basin, with many hilly areas in the territory, rich in wild jujube resources. Due to the warm and humid climate, the jujube shoots grow full and thick, which is very suitable for making jujube leaf tea. The raw materials of jujube leaf tea processed in the following embodiments of the present invention are taken from Chuzhou.

[0022] The specific implementation process and product characteristics of the content of the present invention are further described below:

[0023] (1) Young wild jujube leaves: Every spring, when the total length of wild jujube leaves is 1.5-3.0 cm, it is best to pick. At this time, the moisture content in the young leaves of jujube is about 80%-85%.

Abstract

The invention relates to a processing technology of half-fermentation wild jujube leaf tea, which comprises the following steps of picking tender wild jujube leaves with total lengths of 1.5-3.0cm in spring, cleaning, spreading and airing in the shade till the moisture loss is 20%-30%, using palms to repeatedly knead the wild jujube leaves in the same direction on a wood board till the wild jujube leaves are strip-shaped, drying for the first time at 50-60 DEG C till the moisture content is reduced to 30%-35%, placing into a pottery jar, squeezing, sealing, fermenting for 30-40 days at the room temperature in the shade, using 90-100 DEG C water vapor to conduct green removing for 10-20min after the fermentation is over, drying for the second time till the moisture content is reduced to 8%-12%, taking out for cooling, placing the wild jujube leaves that are dried for the second time into a sealing bag for overnight aging and moisture equilibrium, and obtaining the half-fermentation wild jujube leaf tea that is compact in appearance and soft in taste. Compared with the common wild jujube leaf tea, the wild jujube leaf tea is yellow green in color, soft in taste and rich in flavor, has delicate fragrance and color of the common wild jujube leaf tea, and has higher nutrition, and better flavor and taste.
