Abstract

The invention discloses a processing method of earthworm, vinegar earthworm and application thereof, and relates to the technical field of traditional Chinese medicine processing. Comprises the steps of performing vinegar-stewed treatment on pretreated earthworms in rice vinegar, parching after the rice vinegar is fully absorbed, and setting the length of the earthworms, the dosage of the rice vinegar and the temperature of the parching. In the processing method of the earthworms, through the synergistic effect of rice vinegar moistening and sand stir-frying at a specific temperature, the taste correction effect of the rice vinegar is utilized to effectively cover the fishy smell of the earthworms, and simultaneously, the thermosensitive medicinal material components such as hypoxanthine and the like are reserved to the greatest extent. The processing method has the advantages of simple and clear operation, accurate parameters, high repeatability and good stability, low cost related to raw materials and technology, obvious improvement of the fishy smell of the prepared vinegar earthworm, stable odor correction effect, maximum retention of medicinal substances in the earthworm, and guarantee of consistency of product quality, and is beneficial to realizing standardized production.

Description

Lumbricus processing method, vinegar Lumbricus and application thereof Technical Field The invention relates to the technical field of traditional Chinese medicine processing, in particular to a earthworm processing method, vinegar earthworm and application thereof. Background The earthworm is used as a traditional Chinese medicinal material, contains a plurality of active ingredients such as lumbrokinase, hypoxanthine and the like, and has obvious curative effects on aspects such as antithrombotic, anti-inflammatory, antiasthmatic, diuretic, vein relaxing, heat clearing and convulsion arresting and the like. In clinical application, earthworm is often used for treating diseases such as high fever unconsciousness, convulsion, arthralgia and the like, and the curative effect of the earthworm is widely verified. But the earthworm is rich in protein and volatile components, has strong fishy smell, seriously affects the medication compliance of patients, and limits the popularization of the earthworm in clinical and daily medication. The deodorizing method for animal medicinal materials mainly comprises wine roasting, talcum powder roasting, rice roasting and the like, and aims to improve the smell problem of earthworms, the method is usually adopted for processing the earthworms, but has limitations, for example, the wine roasting method utilizes the volatility and pungent scattering effect of wine to remove fishy smell and correct smell, but can lead to loss of part of water-soluble protein active ingredients, the talcum powder preparation method adsorbs part of peculiar smell ingredients through auxiliary materials, but is easy to cause uneven heating of medicinal materials and influence the medicinal effect, and the milk soaking method reduces fishy smell by virtue of interaction between milk protein and earthworm protein, but has the problems of easy spoilage, higher cost and the like, and has the risk of microbial pollution or deterioration in the storage process. The processing method has unsatisfactory fishy smell removing effect, and is difficult to realize stable and controllable quality standard. The vinegar is used as a common auxiliary material for processing traditional Chinese medicines, acetic acid in the vinegar can be subjected to neutralization reaction with the amine and other fishy smell components in the medicinal materials, and meanwhile, the volatility of the vinegar is favorable for taking away bad smell. In the aspect of processing technology, the prior art mostly adopts a simple soaking or stir-frying mode, and lacks systematic research on key parameters such as vinegar concentration, processing temperature, time and the like, so that the odor correction effect is unstable, and the difference of the retention rate of active ingredients is large. Therefore, the technology for processing the earthworm by vinegar, which is simple and convenient to operate, low in cost and capable of obviously improving the fishy smell of the earthworm and guaranteeing the medicinal components of the earthworm, is urgently needed in the field. In view of this, the present invention has been made. Disclosure of Invention The invention aims to provide a processing method of earthworm, vinegar earthworm and application thereof, so as to solve or improve the technical problems. The invention is realized in the following way: In a first aspect, the invention provides a processing method of earthworm, comprising the following steps: Performing vinegar-stewed treatment on the pretreated earthworms in rice vinegar, and parching after the rice vinegar is fully absorbed; Wherein the length of the earthworms is 0.5cm-3cm, the dosage of the rice vinegar is 15-25% of the weight of the earthworms, and the temperature of the stir-frying treatment is 100-180 ℃. In a second aspect, the present invention provides a vinegar processed earthworm, which is prepared by the earthworm processing method according to any one of the previous embodiments; in the vinegar earthworm, the hypoxanthine content is more than or equal to 0.350mg/g. In a third aspect, the present invention provides a use of the vinegar earthworm according to the preceding embodiment for preparing a medical drug for at least one of the features (1) to (5): (1) Antipyretic, sedative and anticonvulsant; (2) Inhibiting inflammatory response and pain; (3) Clearing and activating the channels and collaterals and improving blood circulation; (4) Dilating bronchi, dilating blood vessels, and inhibiting platelet aggregation; (5) Clear heat and induce diuresis. The invention has the following beneficial effects: According to the earthworm processing method provided by the embodiment of the invention, through the synergistic effect of rice vinegar moistening and sand stir-frying at a specific temperature, the fishy smell of the earthworms is effectively covered by the taste correction effect of the rice vinegar, the formation of flavor substances is promoted by optimizi
