Description

Powdered " Xiancha " tea product

The present invention relates to prepare instant tea, especially belong to the instant tea for preparing with the freeze drying mode.

Described in traditional instant tea manufacture craft such as application number: the 88105853.X " a kind of manufacture method of instant tea " is soak juice with filtering after the tealeaves lixiviate, will soak juice then and carry out the instant tea that drawn behind the concentrate drying; And for example described in the application number 88103042.2 " processing technology of instant tea " it is through pulverizing, filtering the then dry instant tea that is drawn after the squeezing with fresh tea leaf in its, because these methods all are through filtering lixiviate, therefore the cellulose in the tealeaves is by big havoc, the medical effect heavy losses of tealeaves.

The objective of the invention is to: provide a kind of directly tealeaves being rolled to pulverize the instant tea product that the back produces, keep cellulose or other volatile composition in the tealeaves as much as possible, make to produce beyond thought diseases prevention, the effect of curing the disease.

The technical solution used in the present invention is: get fresh tea leaf in its, and selected, decontamination, cleaning completes, quick-frozen, vacuum drying, its improvements are: directly dried tealeaves is rolled the back batching that accounts for gross weight 30% that adds of pulverizing and form; And wherein said completing is meant that the NaOH liquid with 5/10000ths to 10/10000ths concentration carries out the moment high-temperature process; Quick-frozen is meant puts into the tealeaves after completing-40 ℃ to-20 ℃ refrigerating chamber immediately.

The invention has the advantages that: (1) is owing to be directly to roll to pulverize after the employing aged tea leaf drying to make instant tea, therefore cellulose in the tealeaves and the various useful composition in the aged tea leaf can have been kept to greatest extent, therefore drink and help the wriggling of stomach and increase digestive function after this product enters stomach, gastrointestinal disease is had certain curative effect.(2) because tealeaves just rolls pulverizing after only completing, so original green of having preserved tealeaves, delicious flavour is good to eat, and has the natural fragrance of green grass, is a kind of natural green beverage extremely useful to human body, improves a poor appetite after the drink, helps digest.(3) therefore the present invention owing to adopt the fresh aged tea leaf of growth more than 200 days more can turn waste into wealth, and make full use of Resources of Tea Plant.

Specific embodiments of the invention are: get the fresh tea leaf in its of growing more than 200 days, selected, decontamination, the NaOH liquid that adds 5/10000ths to 10/10000ths concentration then carries out after 30 to 90 seconds green removing in high temperature of 100-130 ℃ handle, put it into immediately-40 ℃ to-20 ℃ the refrigerating chamber freezing 4 to 8 hours, then carry out 8 to 12 hours the drying that vacuumizes, enter roller after the drying and roll and be crushed to 60 to 80 orders, add the batching that accounts for gross weight 30% again and modulate and form.

Batching content among the present invention can be selected as required, and each content can on average be selected four kinds of material dryings of dried orange peel, cassia bark, sesame, Radix Glycyrrhizae to mix and roll to wear into 60 to 80 purpose powders and get final product.
