Problems solved by technology

What this method adopts is to remove ginkgolic acid by chemical method, and the price of ginkgo biloba extract (GBE) is expensive, and the enterprise cost is too high, and consumer can't afford it, and can't promote on a large scale
And this method only adds a small amount of ginkgo extract to the tea, so it is difficult to exert the effect of ginkgo tea

Abstract

The invention discloses a preparation method of detoxified ginkgo tea, which comprises the following steps: 1) preparation of a starter: separating Saccharomyces coronoidis from Fuzhuan tea and preparing a solid pure strain starter; 2) ginkgo leaves Pretreatment: wash and remove ginkgo leaves, cut into strips and kill them, and then spread them to cool and knead to obtain raw tea; 3) Ingredients and heaping: after removing impurities, blend them with Heimao tea; the blended tea leaves are steamed once. Heaping after steaming; 4) inoculation: the tea leaves after heaping are steamed twice and then inoculated with solid pure strain starter; 5) Briquetting and fermentation: pressing the tea leaves into tea bricks after inoculation; and placing the tea bricks in Fermentation in the fermentation room; 6) dehydration and packaging: dehydration of the tea bricks after the fermentation is completed, and the dehydrated tea bricks are directly packaged. The method of the invention can not only effectively retain active substances beneficial to the human body, but also reduce the content of ginkgolic acid, and the product quality is safe and reliable, and is suitable for large-scale production and popularization.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a method for preparing detoxified ginkgo tea. Background technique [0002] Ginkgo tea is a health tea refined from ginkgo leaves. In recent years, Ginkgo tea has the functions of lowering blood fat, softening blood vessels, antagonizing platelet activating factor, improving cardiovascular and cerebrovascular circulation and antithrombotic effects. , The effect of relieving fatigue and refreshing is widely accepted and recognized by people. Ginkgo tea contains a variety of active ingredients, including flavonoids, terpenoids, polyprenols, and organic acids. However, Ginkgo tea also contains ginkgolic acid (Ginkgolic Acids, GAs), a toxic and side effect component. According to research reports, ginkgolic acid has effects such as sensitization, cytotoxicity, and liver damage to the human body. If the content of ginkgolic acid in ginkgo tea is not controlled, it will definitely bring...
