Abstract

The invention is a polygala root mould proofing and core pulling method, firstly, putting cleaned polygala root in a sealed glass room, secondly, turning on an ultraviolet lamp in the glass room, and treating for more than 2 hours by ozone to eliminate the existing mould; thirdly, laying for 3-5 days at the temperature of 2-8 ℃, evaporating water slowly, controlling the propagation of mould, promoting the separation of the core and the meat, then spreading to be thin, and drying in the sun to evaporate 20 percent of water; fourthly, core pulling: flattening cortex et radix Polygalae, shaking off cortex et radix Polygalae skin, or directly extracting cortex et radix Polygalae core to obtain semi-finished product of cortex et radix Polygalae; fifthly, drying or sun-drying to obtain the polygala tenuifolia finished product without aflatoxin and core. The method comprises the steps of treating polygala tenuifolia with ozone for more than 2 hours by using an ultraviolet lamp, controlling the aflatoxin of polygala tenuifolia, laying for 3-5 days at the temperature of 2-8 ℃, slowly evaporating water, controlling mold propagation, promoting the separation of core and meat, flattening polygala tenuifolia, shaking off cortex polygalae to separate the cortex polygalae tenuifolia, or directly pumping polygala tenuifolia core to obtain polygala tenuifolia, and drying or airing.

Description

Method for preventing polygala from mildew and conveniently pulling core

Technical Field

The invention relates to a processing technology of polygala tenuifolia, in particular to a method for preventing polygala tenuifolia from mildew and facilitating core pulling.

Background art:

the medicinal part of polygala root is root bark, the medicinal materials are processed into loose core platycodon root and peeled polygala root, and the peeled root bark is called polygala root for short; harvesting cortex et radix Polygalae in the third year after sowing, selecting sunny day in 10 months, cutting off stem and leaf on the surface of rhizoma Phragmitis, and deeply digging

Centimeter, digging out the whole root at one time, piling up the root

Drying in the sun to soft, removing wood core from root, making into cortex et radix Polygalae cylinder, drying in the sun to eight dry, and drying in the sun

And (5) drying under the condition.

The method has the phenomenon that aflatoxin exceeds standard, and the core of fresh polygala tenuifolia is difficult to loose, and the core of polygala tenuifolia is easy to loose after stacking and fermenting for 1-2 weeks in large-scale production. The aspergillus flavus is easily generated by breeding mould in the stacking fermentation process.

The method for producing polygala tenuifolia under the application number 201910609436.3 does not mention the mould prevention and core pulling, and the two methods are all throughout the processing process of polygala tenuifolia.

The processing method of polygala root under the application number 201710257974.1 also has the problems.

The application number 201510539212.1 radix Polygalae fresh-cut processing technology does not mention core-pulling and mold-proof of radix Polygalae.

Disclosure of Invention

The invention particularly provides a method for preventing mould and conveniently pulling core of polygala tenuifolia in order to ensure the quality and the medicinal components of polygala tenuifolia.

Therefore, the technical scheme of the invention is that the polygala tenuifolia mildew-proof and core-pulling-convenient method comprises the following steps of firstly putting cleaned polygala tenuifolia in a sealed glass room, and is characterized in that: secondly, turning on an ultraviolet lamp in the glass room, and treating the glass room with ozone for more than 2 hours to eliminate the existing mold;

thirdly, laying for 3-5 days at the temperature of 2-8 ℃, evaporating water slowly, controlling the propagation of mould, promoting the separation of the core and the meat, then spreading to be thin, and drying in the sun to evaporate 20 percent of water;

fourthly, core pulling: flattening cortex et radix Polygalae, shaking off cortex et radix Polygalae skin, or directly extracting cortex et radix Polygalae core to obtain semi-finished product of cortex et radix Polygalae;

fifthly, drying or sun-drying to obtain the polygala tenuifolia finished product without aflatoxin and core.

Has the advantages that:

the method utilizes an ultraviolet lamp, treats polygala root with ozone for more than 2 hours, effectively controls aflatoxin of polygala root, lays for 3-5 days at the temperature of 2-8 ℃, controls mould propagation, slowly evaporates water, dries in the sun after being spread thin to evaporate 20 percent of water due to different water contents of the skin and the core of polygala root, slowly evaporates to promote the separation of the core and meat, flattens polygala root to shake off polygala root skin to separate polygala root skin or directly pumps polygala root core to obtain polygala root semi-finished product due to certain toughness of the skin of polygala root; oven drying or sun drying to obtain radix Polygalae product without aflatoxin and core.

Detailed Description

The invention provides a polygala root mould proofing and core pulling facilitating method, which comprises the steps of firstly placing cleaned polygala root in a sealed glass room, secondly turning on an ultraviolet lamp in the glass room, and treating for more than 2 hours by ozone to kill existing moulds;

thirdly, laying for 3-5 days at the temperature of 2-8 ℃, evaporating water slowly, controlling the propagation of mould, promoting the separation of the core and the meat, then spreading to be thin, and drying in the sun to evaporate 20 percent of water;

fourthly, core pulling: flattening cortex et radix Polygalae, shaking off cortex et radix Polygalae skin, or directly extracting cortex et radix Polygalae core to obtain semi-finished product of cortex et radix Polygalae;

fifthly, drying or sun-drying to obtain the polygala tenuifolia finished product without aflatoxin and core.
