Problems solved by technology

[0013] It can be seen that the preparation process is medium and low temperature extraction, and then the extract is filtered, the filtrate is concentrated under reduced pressure, spray dried or dried under reduced pressure, the extract is directly filtered, and the filtration volume is large, which is not only time-consuming and labor-intensive, but also difficult to achieve in terms of efficiency and effect. It is guaranteed that the active ingredients and yield of the product are low when tea coarse powder is used as raw material for medium and low temperature extraction

Abstract

The invention relates to a Pu'er tea extract, and a preparation method and application thereof. The Pu'er tea extract is high in active ingredient content and can reduce blood sugar and blood fat obviously. By the preparation method of the Pu'er tea extract, the active ingredients are completely and effectively converted and dissolved out and the original flavor of the Pu'er tea is maintained. The process of the Pu'er tea extract has the advantages of guaranteeing the clarity of the finished products which are dissolved in cold water and hot water and reducing the work load of later centrifugation, along with low cost, industrialization and stable and controllable quality.

Description

technical field [0001] The invention relates to a tea product, in particular to a Pu'er tea extract capable of lowering blood sugar. Background technique [0002] In recent years, due to changes in people's production, living and environmental conditions, on the one hand, overall resources have been destroyed, air and water quality have been polluted to varying degrees, pesticides remain in some vegetables and fruits, and feed hormones in some meats have not been completely decomposed. , which greatly increases the working pressure of the pancreas, the detoxification organ of the human body. Often, this leads to insufficient insulin production in the body; Physical labor reduces physical exertion and increases the accumulated calories in the body, leading to an increase in insulin consumption. As a result of the combined effects of the two aspects, the incidence of diabetes, fatty liver and other diseases has increased significantly. At present, diabetes has become the thir...
