Problems solved by technology

Hot air deenzyming is to use the thermal radiation generated by hot and dry air to increase the temperature of leaves and destroy the activity of oxidase in tea leaves to achieve the purpose of deenzyming, but it has the disadvantages of high energy consumption and large damage to nutrients; microwave deenzyming uses the thermal effect of microwaves and biological The effect is to passivate the oxidase activity in tea leaves, and the efficiency is high, but the investment in equipment is large

Abstract

A method for preparing tea bag by oriental blueberry leaves comprises the following steps of: (A) crushing, that is, performing mechanical crushing of oriental blueberry leaves twice; (B) soaking, that is, mixing the crushed oriental blueberry leaves with water, and soaking; (C) suction filtration, that is, performing suction filtration to realize slag-liquid separation so as to obtain soaked oriental blueberry leaves; (D) enzyme deactivation, that is, performing enzyme deactivation of the soaked oriental blueberry leaves by steam; (E) drying and sterilization, that is, drying and sterilizing the oriental blueberry leaves after enzyme deactivation by hot air circulation; (F) bagging, that is, bagging the dried and sterilized oriental blueberry leaves. The oriental blueberry leaf tea bag prepared by the invention has natural fragrance of oriental blueberry leaves, and high health care value, and thus the invention enlarges the application scope of oriental blueberry leaves, and improves the economical value of oriental blueberry leaves.

Description

technical field [0001] The invention relates to the technical field of agricultural products and food processing, in particular to a method for preparing teabags from the leaves of the black rice tree. Background technique [0002] Vaccinium bracteatum Tbunb belongs to Rhododendronaceae and belongs to the genus Vaccinium. Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty recorded: "The leaves of the black rice tree have a bitter, flat, and non-toxic smell. It is mainly used to relieve diarrhea and eliminate sleepiness, strengthen muscles and strength, take it for a long time, lighten the body for many years, make people not hungry, and turn white but old." The chemical components contained in the leaves of black rice tree are quercetin, p-hydroxycinnamic acid, ursolic acid, triundecane, isoorientin, unkissed terpene (ketone) and oleanolic acid. In addition, the leaves are also rich in amino acids and organic acids. The organic acids mainly include oxalic acid...
