Ground beetle processing method

Abstract

A ground beetle processing method comprises the following steps: scalding living ground beetles with boiling water until the ground beetles are dead, steaming the dead ground beetles on a plate for at least 100 min, and drying the steamed ground beetles in an open oven. The method further comprises the following steps: scalding the living ground beetles with boiling water until the ground beetles are dead, immediately steaming the dead ground beetles on a plate for at least 120 min, and immediately drying the steamed ground beetles in the open oven for 3-8 h. The processing method has the characteristics of simple processing process, effectiveness in control of the aflatoxin content of ground beetle decoction pieces, obviousness in reduction of acid-insoluble ash, improvement of the quality of products, enhancement of the safety of the products, and guaranteeing of people's medication safety.

Description

technical field [0001] The invention relates to a processing method of wood beetle, which belongs to the technical field of pharmacy. Background technique [0002] The ground beetle is the dried female body of Eupolyphaga sinensis Walker or Steleophagaplancyi (Boleny), an insect of the cockroach family. The processing method stipulated in the 2015 edition of "Chinese Pharmacopoeia" is: after catching, scald to death in boiling water, and dry or dry. But the prior art also includes scalding the ground beetle to death in milk, and then drying or drying; in addition, there is a method of freeze-drying the ground beetle. [0003] Although the current version of the "Chinese Pharmacopoeia" 2015 edition does not stipulate the standards for aflatoxin, China has clear regulations on the limit of aflatoxin in food, and the food standard GB2761-81 and GB2715-81 control the upper limit of aflatoxin B1 The maximum is no more than 20ug / kg. Most countries in the world control the total ...

Problems solved by technology

[0005] The traditional production process of wood beetles is: scald to death in boiling water → sun or dry. During the processing of this traditional process, after the fresh and alive wood beetles are scalded to death by boiling water, the water content of the insect body is high, and the shell has an oily film. Chinese medicine decoction pieces The traditional drying methods in the industry are still drying in the sun and drying in a tunnel oven. The heat transfer efficiency of the drying process is low. Because the heat transfer efficiency of the tunnel oven is improved, the incoming hot air will be recirculated and used, and the mass transfer efficiency is low. Causes subsequent drying times to be long

In mass production, even in summer, it takes 3-4 days to dry in the sun; the tunnel oven also takes more than 2 days to dry, intermittent drying method, during the intermittent period, aflatoxin is very easy to breed, As a result, the aflatoxin has greatly exceeded the safety standard requirements
