Problems solved by technology

However, this tea has certain deficiencies: first, the tea body particles are relatively large, and it is difficult to extract all the active ingredients in the tea leaves in a short time when making tea, which affects the nutritional value and efficacy of the tea; There is a certain amount of grass flavor of wild Maojian grass remaining, and the taste is poor
The above shortcomings have seriously affected the quality image of Maojian fitness tea, and also affected the economic benefits of Maojian grass resource development

Embodiment 1

[0026] A preparation method of Maojian fitness instant tea, comprising the steps of:

[0027] (1) Enzyme treatment: soak the tea leaves in 8A water first, adjust the pH to 5.5 with citric acid, heat to 42°C and add tannase, cellulase and pectinase at this temperature for enzyme treatment, and timely Stirring is carried out, and the enzyme treatment time is 28-35min. The dosages of the tannase, cellulase and pectinase are 4.05A%, 2.7A%, 0.9A%.

[0028] (2) Extraction: After enzyme treatment, add 20A of water again, extract at 90°C under normal pressure for 44 minutes, then filter and squeeze, and squeeze out all the juice to obtain a first-time soaking juice and a first-time liquid slag; the first-time liquid Add 10A of water to the slag for secondary leaching, extract at 90°C for 34 minutes under normal pressure, filter and squeeze again, and squeeze out all the juice to obtain the secondary leaching juice and secondary liquid slag. The tea juice and tea dregs obtained after...

Abstract

The invention relates to a method for preparing instant Maojian tea capable of building bodies from black Maojian tea as a raw material, belonging to the technical field of health beverages, and solving the problems of large granules, poor instant solubility, low nutritional value and poor mouth feel of existing Maojian tea capable of building bodies. The method comprises the concrete steps of adding water for soaking the black Maojian tea raw material; adding tannase, cellulase and pectinase for enzymatically hydrolyzing; adding beta-cyclodextrine and sodium hydrogen sulfite for well extracting effective ingredients from the raw materials; removing impurities; concentrating; drying; packaging. The method is simple in process. The instant Maojian tea prepared by adopting the method is high in effective ingredient content, moderate in tea granule size, good in porosity, convenient to dissolve in water, fresh and bright in tea soup color, rich in fragrance, and fragrant and slightly sweet in mouth feel.
