Embodiment 1

[0024] A kind of processing method of clover green tea, concrete steps are as follows:

[0025] 1) Select the effective part: select the leaf part of the 2-3-year-old fresh raw medicinal material Clover clover at the cultivation base in June, and remove the non-medicinal part;

[0026] 2) Clean selection: The leaves collected in step 1) are removed by selection and water selection, that is, after removing rotten leaves and moth-eaten plaques, soak them in detergent with a mass fraction of 0.1% for 30 minutes, and then use Rinse with running water for 30 minutes until there is no foam, then flatten and dry to remove most of the water on the leaf surface, and freeze at -40°C overnight to maintain the freshness of the leaves;

[0027] 3) Drying: Use a cold trap to pre-cool the iron frame plate for 30 minutes until the temperature is lower than -45°C, keep it for 10 minutes, quickly take out the frozen leaves and place them on the iron frame plate, vacuumize to 2.0Pa, and freeze-d...

Embodiment 2

[0031] A kind of processing method of clover green tea, concrete steps are as follows:

[0032] 1) Select the effective part: select the leaf part of the 2-3-year-old fresh raw medicinal material Clover clover at the cultivation base in August, and remove the non-medicinal part;

[0033] 2) Clean selection: The leaves collected in step 1) are removed by selection and water selection, that is, after removing rotten leaves and moth-eaten plaques, soak them in detergent with a mass fraction of 0.1% for 30 minutes, and then use Rinse with running water for 30 minutes until there is no foam, then flatten and dry to remove most of the water on the leaf surface, and freeze at -40°C overnight to maintain the freshness of the leaves;

[0034] 3) Drying: Use a cold trap to pre-cool the iron frame plate for 20 minutes until the temperature is lower than -45°C, keep it for 10 minutes, quickly take out the frozen leaves and place them on the iron frame plate, vacuumize to 2.0Pa, and freeze...

Embodiment 3

[0038] A kind of processing method of clover green tea, concrete steps are as follows:

[0039] 1) Select the effective part: select the leaf part of the 2-3-year-old fresh raw medicinal material Clover clover at the cultivation base in September, and remove the non-medicinal part;

[0040] 2) Clean selection: The leaves collected in step 1) are removed by selection and water selection, that is, after removing rotten leaves and moth-eaten plaques, soak them in detergent with a mass fraction of 0.1% for 30 minutes, and then use Rinse with running water for 30 minutes until there is no foam, then flatten and dry to remove most of the water on the leaf surface, and store at -40°C ultra-low temperature overnight to maintain the freshness of the leaves;

[0041]3) Drying: Use a cold trap to pre-cool the iron frame plate for 25 minutes until the temperature is lower than -45°C, and keep it for 10 minutes. The frozen leaves are quickly taken out and placed on the iron frame plate, va...

Abstract

The invention discloses a processing method for radix tetrastigme tea. Coarse radix tetrastigme powder obtained by performing selection, impurity removal, drying, wall breaking and smashing on leaf parts of radix tetrastigme is packaged in vacuum in a sealed manner and then is stored in shade. By a freeze-drying method, the completeness of the biochemical structure and the activity of radix tetrastigme leaves are retained, and the obtained radix tetrastigme tea powder is loose, is high in rehydration capability, smells mellow and is easy to cut and smash; the form, the color and the taste of the radix tetrastigme tea powder are higher than those of the tea powder prepared by the conventional technology. The produced powdered radix tetrastigme tea can be stored for a long time and is convenient to transport, and effective medicinal components of the radix tetrastigme are retained to the maximum extent. The processing method is easy to operate, high in speed and high in efficiency; the medicinal components of the radix tetrastigme can be effectively retained, so that the radix tetrastigme tea can be stored under a natural condition for a long time and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of beverages, and in particular relates to a freeze-drying processing method of three-leaf green tea. Background technique [0002] In the early 19th century, Altmans pioneered freeze-drying technology, which was applied to the research of tissues and organs of biological samples. In 1909, in order to facilitate the storage of samples and avoid the instability of samples at high temperatures, Schackcll used a very primitive vacuum pump, used salt and ice as refrigerants, and used sulfuric acid as desiccant, and published the freeze-drying experiment report in Am.J.Physiol. In 1921, H.F.swift proposed the standard freeze-drying method for preserving bacterial strains, and combined freezing and drying under low pressure to produce biological materials without deformation, damage, and less loss of components. After the Second World War, the application of freeze-drying technology in medical research is very common. my ...
