Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of preparation method of Saussurea involucrate fruit tea, Smallantus sonchifolium stem tuber is made dry Smallantus sonchifolium fourth, mixed black tea, effectively reduce the side effect of Smallantus sonchifolium, improve the utilization ratio of Smallantus sonchifolium simultaneously.
The preparation method of a kind of Smallantus sonchifolium of the present invention, comprises the following steps:
Step one, Smallantus sonchifolium is cut into granularity is 4-10 object Smallantus sonchifolium fourth; After described Smallantus sonchifolium makes fourth, effectively shorten dry required time, reduce the damage to described Smallantus sonchifolium active ingredient.
Step 2, described Smallantus sonchifolium fourth is dropped into blanching 1-2min in boiling water, immerse in cold water immediately after pulling out and cool.Blanching treatment to go out enzyme and sterilizing to described Smallantus sonchifolium fourth, prevents described Smallantus sonchifolium fourth from because of oxidation, variable color occurring.
Step 3, described Smallantus sonchifolium fourth obtained for step 2 is put into colour protecting liquid soak at room temperature 5-10min, then clear water rinsing drains; Described color retention can effectively prevent described Smallantus sonchifolium fourth from because being exposed in air, variable color occurring.
Step 4, alternating temperature are dry
Step 3 is obtained described Smallantus sonchifolium fourth, be placed in air dry oven, dry 4-5h in 40-50 DEG C, then adjust described drying box temperature and dry 1-2h to 60-70 DEG C, finally adjust described drying box temperature and dry 5-6h to 40-50 DEG C.Owing to containing a large amount of compound sugar in Smallantus sonchifolium, when drying, the too high meeting of temperature causes coking and is adhered, and described alternating temperature is dry, and its initial temperature is low, and internal moisture diffusion control is preponderated, and accelerates moisture and shifts to surface; Mid-term, temperature raised, and surface vaporization is preponderated, and surface moisture evaporation is accelerated, and the later stage reduces baking temperature, can effectively prevent inner sugar diffusion and be adhered, and impact is dry.Meanwhile, described baking temperature controls below 70 DEG C, effectively reduces the minimizing of compound sugar in described Smallantus sonchifolium.
Step 5, microwave treatment
The described Smallantus sonchifolium fourth that step 4 is obtained carries out microwave treatment, and described microwave power is 150-300W, and the processing time is 2-5 second.Described microwave treatment effectively shortens the time of described Smallantus sonchifolium fourth high temperature drying, reduces the loss of compound sugar in described Smallantus sonchifolium fourth.
Step 6, baking
The described Smallantus sonchifolium fourth that step 5 is obtained is placed in baking box toast, presents golden yellow to described Smallantus sonchifolium fourth.Described baking can improve the mouthfeel of described Smallantus sonchifolium fourth, and make described Smallantus sonchifolium fourth golden yellow color, mouthfeel is good.
Step 7, mixed black tea
Add black tea in the described Smallantus sonchifolium fourth that step 6 is obtained to mix, bag distribution packaging.In described Smallantus sonchifolium fourth, add black tea, can effectively neutralize the cold of described Smallantus sonchifolium, improve human body to the absorption of active ingredient in described Smallantus sonchifolium simultaneously.
Preferably, the described Smallantus sonchifolium fourth in described step 7 is with parts by weight 60-70 part, and described black tea is with parts by weight 30-40 part.
Preferably, described colour protecting liquid is selected from one or more in the citric acid of 0.1%-0.2%, 0.5% ascorbic acid and 0.05%-0.1% sodium sulfite.
Preferably, described colour protecting liquid is the citric acid of 0.2%.
Preferably, described baking time is 5-10min, and baking temperature is 70-80 DEG C.
Preferably, described black tea is selected from the common black tea of commercially available finished product, such as, be Pu'er tea.
Preferably, the antioxidant of 1-2 weight portion can also be added in described step 7.
Wherein in an embodiment, the preparation method of a kind of Saussurea involucrate fruit tea of the present invention, comprises the following steps:
Step one, the Smallantus sonchifolium stem tuber selected completely filled fruit, go mouldy without disease and pest, nothing, such as, clean to avoid repeated contamination with circulating water, removed the peel by the described Smallantus sonchifolium stem tuber cleaned, and being cut into granularity is such as 4-10 object Smallantus sonchifolium fourth.
Step 2, described Smallantus sonchifolium fourth is put into boiling water blanching 2 ~ 6min, to go out enzyme and sterilizing, immerse in cold water immediately after blanching and cool rapidly.
Step 3, described Smallantus sonchifolium fourth obtained for step 2 is put into colour protecting liquid, described colour protecting liquid is such as the citric acid of 0.1%-0.2%.And 5-10min is soaked under normal temperature, then clear water rinsing drains.
