Processing technology of cold-soluble burdock flower and fruit instant tea

Abstract

The invention provides a processing technology of cold-soluble burdock flower and fruit instant tea, which comprises the following steps: taking burdock tea powder, adding water, pectinase, tannase and additive powder, fully stirring and uniformly mixing by using mixing and stirring equipment, and extracting a burdock tea extracting solution; performing centrifugal treatment on the burdock tea extracting solution to obtain centrifugal liquid; performing ultrafiltration on the centrifugate to obtain filtrate; and concentrating and drying the filtrate to obtain the instant burdock tea. According to the processing technology of the cold-soluble burdock flower and fruit instant tea provided by the invention, burdock tea powder, water, pectinase, tannase and additive powder are fully and uniformly mixed and extracted by utilizing mixing and stirring equipment, and then filtration is performed by adopting ultrafiltration, so that the instant solubility of the burdock tea is improved, and pollen or fruit powder can be added in the preparation process, so that the taste of the burdock tea is improved; and the uniform mixing and stirring equipment adopts simultaneous operation of bidirectional shaking and stirring, so that the mixing uniformity of the solution is enhanced.

Description

technical field [0001] The invention mainly relates to the technical field of burdock tea, in particular to a processing technology of cold-soluble burdock flower and fruit instant tea. Background technique [0002] Instant tea is generally made by extracting tea leaves with hot water (temperature above 80°C) and then filtering or centrifuging, concentrating and drying. It is a solid powder that can quickly dissolve in water, has no tea residue and maintains the unique flavor of tea. It is ready to drink. It can also be used as a raw material for food and beverages. With the above-mentioned processing method, the cold solubility of the instant tea product is poor. If it is dissolved in water at 5°C, there will be obvious insoluble particles in the water. [0003] In the prior art, there are instant teas that can be dissolved in ice water for types such as white tea, black tea, and yellow tea, but there is no cold-dissolving instant tea for burdock tea. Therefore need to pr...

Problems solved by technology

Using the above-mentioned processing method, the cold solubility of instant tea products is poor. If it is dissolved in water at 5°C, there will be obvious insoluble particles in the water.

[0003] In the existing technology, there are instant teas that can be dissolved in ice water for types such as white tea, black tea, and yellow tea, but there is no cold-soluble instant tea for burdock tea.
