Abstract

The invention relates to a tea beverage making technology, and concretely relates to an Ampelopsis grossedentatac tea beverage extracting method. The method comprises the following steps: carrying out enzyme deactivation of a fresh Ampelopsis grossedentatac raw material, carrying out pile fermentation, steaming, sprinkling Eurotium cristatum spore powder, sealing tea leaves, sterilizing, fermenting the tea leaves, fermenting the tea leaves, extracting, filtering, and mixing. The adoption of a large amount of the Eurotium cristatum spore powder in the method to carry out rapid fermentation reduces the infectious microbe growth, does not cause the moldy problem of the tea leaves, and avoids the influences of the culture medium in a Eurotium cristatum liquid to the original flavor of the tea leaves. The addition of Ampelopsis grossedentatac leaves can substantially inhibit the growth of harmful bacteria, and the common fermentation of the Ampelopsis grossedentatac and a raw dark green tea can effectively improve the flavonoid substances in the tea leaves and is in favor of improving the mouthfeel of the Ampelopsis grossedentatac tea. A large amount of dihydromyricetin in the Ampelopsis grossedentatac is converted into soluble fragrant substances, and the flavonoid substances in the Ampelopsis grossedentatac tea are greatly utilized to increase the healthcare functions of the Ampelopsis grossedentatac tea.

Description

Technical field: [0001] The invention belongs to the field of biological fermentation, and relates to a tea beverage production process, and more specifically relates to a method for extracting Maoyan berry tea beverage. Background technique [0002] Maoyanberry is also known as Tujia Ganlu, Tujia God Tea, Guanyin Grass and so on. Its active ingredients are mainly dihydromyricetin and flavonoids, and it also contains 17 essential amino acids such as leucine, isoleucine, and methionine, and 14 trace elements such as potassium, calcium, iron, zinc, and selenium, among which flavonoids are the highest The detection content is 9.31%, which is the highest flavonoid content among all plants found so far, and is called the "king of flavonoids" in plants. Maoyanberry is mainly wild in selenium-rich areas such as Zhangjiajie, and the content of selenium in Maoyanberry leaves is relatively high. Selenium is closely related to the occurrence and development of diabetes. Studies have...
