Abstract

The invention discloses an efficient processing method of Chinese caterpillar fungus. The method comprises the following steps of: putting fresh Chinese caterpillar fungus into acid normal saline of which the pH value is 2-4 for soaking in a way that the Chinese caterpillar fungus is fully submerged below the liquid surface; slightly overturning once every 10-20 minutes; washing the Chinese caterpillar fungus till surface-attached impurities are removed; taking the washed Chinese caterpillar fungus out; standing at the room temperature for 25-35 minutes; transferring wet Chinese caterpillar fungus into liquid nitrogen; taking the Chinese caterpillar fungus out 25-35 seconds later; smashing; and quickly packaging in vacuum. By adopting the processing method, the nutrition and functional activity losses of the picked Chinese caterpillar fungus can be prevented in the processing process, browning of the Chinese caterpillar fungus is avoided, and the Chinese caterpillar fungus is hardly polluted by harmful microorganisms when stored for a long time.

Description

A kind of high-efficiency machining method of Cordyceps
Technical field
The invention belongs to technical field of Chinese medicines, be specifically related to a kind of high-efficiency machining method of Cordyceps.
Background technology
Cordyceps plantworms; Entomophyte claims " Cordyceps ", " Cordyceps " again, is to originate in the geographic rare medicinal herbs simply in Yunnan Province of China, Sichuan, Tibet and Qinghai.For Clavicipitaceae fungus Cordyceps colonizes in Stroma and the dry composite body of larva corpse on the Hepialidae insect larvae; This property of medicine is sweet equals, returns lung, kidney channel; And the effect that kidney-supplementing liver-boosting, hemostasis and phlegm are arranged is used for deficiency of kidney essence, impotence and seminal emission, soreness of waist and knee joint, chronic cough dyspnea due to deficiency, chronic cough spitting of blood.
The output of Cordyceps is lower, and demand is very vigorous, and the bright Cordyceps after plucking is difficult to storage and transport, and the medicinal herb grower adopts the sunshine method that Cordyceps is at source dried after harvesting usually at present, and this also is the way that for many years numerous medicinal herb growers extensively taked.This method efficient is low, water content is not easy control; And receive weather effect bigger, Cordyceps volume-diminished in the dry run, the obvious brown stain of color and luster meeting; Influence outward appearance; Also receive harmful microbial contamination easily, nutrition and the functional activity of Cordyceps also have bigger loss in the process of drying simultaneously, also do not have a kind of desirable effective method to solve this technical problem at present.
Summary of the invention
The purpose of this invention is to provide a kind of high-efficiency machining method that prevents Cordyceps nutrition and Cordyceps of functional activity loss in plucking the post-treatment process.
The objective of the invention is to realize in the following manner:
A kind of high-efficiency machining method of Cordyceps, this method may further comprise the steps: get fresh Cordyceps, put into pH value and be 2~4 acid normal saline and soak; The complete submergence Cordyceps of liquid level was overturn once in per 10~20 minutes gently, Cordyceps is washed till the surface nothing adheres to impurity; Take out washed Cordyceps, room temperature was placed 25~35 minutes, changed in the liquid nitrogen when keeping Cordyceps moistening; Take out after 25~35 seconds, pulverize, vacuum-packed rapidly.
Described pH value is that 2~4 acid normal saline is for regulating the normal saline of pH value through citric acid.Compare with other acidic materials, citric acid is easy to be easy to get, safety non-toxic, and Cordyceps can effectively maintain active component through in the normal saline of its adjusting, soaking.
Above-mentioned soak time is preferably 0.5~1.5 hour, and the upset number of times is 3~4 times.The liquid nitrogen temperature of using is-194~-198 ℃, and the preferred liquid nitrogen temperature of using is-196 ℃.The pulverizing time is 1~1.5 minute, and preferably the pulverizing time is about 1 minute, is crushed to 200 orders~400 orders.
The most preferred method of Cordyceps highly-efficient processing of the present invention is: get fresh Cordyceps, be no more than 8 hours apart from gathering, put into pH value and be 2~4 acid injection normal saline (be preferably mass percentage concentration be 0.9% sodium-chloride water solution) immersion 1 hour; The complete submergence Cordyceps of liquid level overturn in per 15 minutes gently, impurity such as the silt that adheres on the removal Cordyceps surface, dust; Take out washed Cordyceps with bamboo let, room temperature was placed in the porcelain dish about 30 minutes, kept the moistening of Cordyceps; Polypide is changed in the liquid nitrogen; Liquid nitrogen temperature is about-196 ℃, takes out after 30 seconds, puts into the spheroid mill and pulverizes 1~1.5 minute; Be crushed to 200 orders~400 orders, Cordyceps is sealed with aluminium foil bag is vacuum-packed rapidly.
In addition, the present invention has tried out the container of various material, finds to adorn Cordyceps to container with bamboo length, and it is comparatively suitable to change in the liquid nitrogen container again, and easily Cordyceps is poured out after taking out, not sticking wall.
When Cordyceps was pulverized, the time was unsuitable long, get final product in 1~1.5 minute, both can guarantee the fineness pulverized, can avoid equipment heating destruction nutritional labeling in the crushing process again.
Adopt Cordyceps that processing method of the present invention obtains and the comparison of shining the Cordyceps active constituent content that drying method obtains:
Laboratory sample: get bright Cordyceps, be no more than 8 hours apart from gathering.
Method 1, dry Cordyceps: between 4~June of collection period, dry after bright Cordyceps is removed mud in the Qinghai-Tibet Platean Cordyceps, under the sunshine sufficiency, directly to dry in 2~3 days, the Cordyceps weight after drying is 20% of bright Cordyceps, under 4 ℃ of conditions, preserves 12 months.
Method 2, Cordyceps powder:, under 4 ℃ of conditions, preserved 12 months according to the Cordyceps powder that the embodiment of the invention 1 method prepares.
Content assaying method:
1, with reference to " Chinese food journal " in June, 2007, P144~149, Gu Zhenyu etc. publish an article: the assay method of cordycepic acid, cordycepin in " content of cordycepin and cordycepic acid in the high effective liquid chromatography for measuring Cordyceps ".
2, the Cordyceps polysaccharide detection method is with reference to the assay method of polysaccharide under Ganoderma item of 2010 editions pharmacopeia.
3, the adenosine detection method is with reference to the assay method of adenosine under Cordyceps item of 2010 editions pharmacopeia.
The Cordyceps that fresh Cordyceps, processing method of the present invention are obtained compares with the active constituent content and the outward appearance of shining the Cordyceps that drying method obtains, and the result sees table 1:
Table 1
The result: under 4 ℃ of conditions, preserving 12 months effects with the Cordyceps powder of the inventive method preparation does not have destruction, the polypide invariant color, and the outward appearance abnormal smells from the patient is all good.Drying Cordyceps weight is about 20% of bright Cordyceps, so corresponding functional component content should be divided by about 5, but through active constituent content measuring, can dry adenosine in the Cordyceps, cordycepin, cordycepic acid has greater loss when drying, and the browning that darkens.
" % " of the present invention is the quality percentage composition.
With prior art beneficial effect more of the present invention: with prior art relatively, processing method of the present invention is soaked in pH value is 2~4 acid normal saline and can fully be removed silt and keep the polypide even tissue full; In liquid nitrogen, placing can be rapidly with the polypide sclerosis, the convenient pulverizing.Processing method of the present invention has prevented that Cordyceps nutrition in plucking the post-treatment process runs off with functional activity, and color and luster can brown stain, and outward appearance is good, and long-term the placement is difficult for receiving being harmful to microbial contamination.
