Preparation method of cordyceps sinensis micropowder lozenges

Abstract

A preparation method of cordyceps sinensis micropowder lozenges relates to a technology that the cordyceps sinensis is smashed through an ultra-low temperature smashing method and then is frozen and dried to produce the cordyceps sinensis micropowder which serves as the raw material, and then the raw material is rehydrated and pressed to obtain the cordyceps sinensis micropowder lozenges. The method comprises the following steps: first: freezing the cordyceps sinensis with water content not less than 5 percent to be below 0 DEG C, and smashing under the temperature not higher than 0 DEG C; directly freezing and drying the non-defrosting cordyceps sinensis micropowder obtained through smashing, wherein the water content of the micro powder at the moment is not higher than 3 percent (weight); forwards, rehydrating the frozen and dried cordyceps sinensis micropowder; allowing the water for rehydration to be subjected to ultrasonic atomization so as to obtain water mist which is input into the frozen and dried micro powder; meanwhile, stirring the frozen and dried micro powder so as to allow the water content to be raised to 4-20 percent (weight), and obtaining the rehydrated micro powder with the water percent of 4-20 percent (weight); and tabletting the micro powder so as to obtain the cordyceps sinensis micropowder lozenges with the water content not high than 20 percent (weight). The cordyceps sinensis micropowder with water content lower than 8 percent can be directly pressed into the lozenges with uniform water content, and the method for controlling the water content is simple and precise.

Description

technical field [0001] The invention relates to a technique for preparing a micropowder of Cordyceps sinensis with low water content by using Cordyceps micropowder obtained after ultralow temperature pulverization and freeze-drying as a raw material, rehydrating and pressing into tablets. It belongs to the scope of medicine, food and health products. Background technique [0002] Cordyceps sinensis (Cordyceps sinensis) It is a precious traditional Chinese medicine with a history of thousands of years in China. Modern medical research shows that Cordyceps sinensis has various effects such as regulating immune system function, anti-tumor, and anti-fatigue. The active ingredients in it, such as polysaccharides containing protein subunits, and various proteins and enzymes with anti-cancer, anti-tumor and immune-initiating abilities, will be hydrolyzed and destroyed under excessively high temperature conditions. This makes the traditional way of utilizing Cordyceps sinensis in...

AI Technical Summary

Problems solved by technology

The micropowder is very viscous after adding water directly, and it is difficult to mix evenly. When using this method, the water content of the micropowder is less than 8% and cannot be pressed into tablets.

In the patent application with the application number 201210128486.8, it is disclosed that firstly, Cordyceps sinensis with a water content of less than 9% is prepared into a nano-powder, and then the nano-powder is added to water with a weight of 2 to 6 times to prepare a homogenate, and then the homogenate After freeze-drying, crush again, mix the original nano-powder for tableting, because it is difficult to directly take samples for moisture determination during the working process of the freeze-drying machine, and the moisture content of the material cannot be accurately controlled through a freeze-drying process, so it has to be dried in the freeze-dried powder The original nano powder is added to adjust the water content, which makes it difficult to accurately control the water content of the material before tableting

In the process of freeze-drying the homogenate into medicinal powder, because the viscous substances in the cells of Cordyceps sinensis are dissolved in water after adding water to the homogenate, during the freeze-drying process, the material is layered in the homogenate during freezing, and the blocky material after freeze-drying The composition of the powder is not uniform, the surface turns black, and the inside is gray. It needs to be pulverized again to get a relatively uniform micropowder, which makes the production process more complicated.
