Processing method of ginger processed pinellia

Abstract

The invention provides a processing method of ginger processed pinellia. The processing method comprises the following steps: taking ginger slices and decocting; adding pure pinellia and immersing until the center of pinellia is immersed with the soup; adding alum and continually immersing for 48-72 hours; taking out and steaming; then cooling and slicing; and naturally drying or drying at a low temperature to obtain a finished product. The use amount of the ginger accounts for 25wt% of the pure pinellia and the use amount of the alum accounts for 6wt%-8wt% of the pure pinellia. According to the processing method, the use amount of auxiliary materials is reduced and medicinal materials are pre-treated and steamed, so that the use amount of the alum is greatly reduced, and the effects of detoxifying and removing irritation are guaranteed; effective components of pinellia are kept to the greatest extent; furthermore, the ginger processed pinellia processed by the method has a better finished product shape and high yield; modern equipment can be used for realizing standardized production and parameters of a processing process can be accurately controlled; and the influences of manual subjective factors are reduced, so that the quality of the product is more stable and controllable.

Description

technical field [0001] The invention relates to the field of processing and processing of Chinese medicinal materials, in particular to a processing method of ginger pinellia. Background technique [0002] Pinellia ternata is an araceae plant whose tubers are used for medicine. Because of its pungent taste, tongue numbness and stinging throat, it has the irritant of "halving the throat", and because of its neurotoxicity, it is listed as a drug-type traditional Chinese medicine. In order to reduce its irritation and toxicity, it often needs to be processed before medicinal use. At present, pinellia can be divided into Qing Pinellia, Jiang Pinellia and Fa Pinellia according to its processing method. Among them, ginger pinellia is one of the most commonly used processing methods. [0003] The processing method of the ginger pinellia included in the 2010 edition of "The Pharmacopoeia of the People's Republic of China" is as follows: take the pinellia clean, separate the size,...

Problems solved by technology

[0004] But the auxiliary material consumption of this method is bigger, especially the consumption of alum, reaches 12.5% ​​of net pinellia, on the one hand, alum is a toxic raw material, and Pharmacopoeia also stipulates strict limits to the content of alum in the ginger pinellia finished product, promptly does not More than 8.5%, the Jiang Pinellia prepared by the method of Pharmacopoeia, its alum residue is generally 6%-8%

On the other hand, due to the large amount of alum, when cooking with ginger and pinellia, it is easy to stick to the bottom of the pan, making the finished product of ginger pinellia poor in character and low in yield. The yield of this method is generally 70%. Left and right; in order to reduce sticking to the bottom of the pan, constant stirring is required, which makes the operator labor intensive

In addition, in addition to the precise control of the amount of raw materials and auxiliary materials, this method has no clear control over the parameters of the processing process. The controllability of the processing process is poor, and it needs to be completed in sections. The process is cumbersome and is not conducive to industrialized standardized production.

In addition, the ginger pinellia obtained by this method has poor quality stability.
