Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with examples.

[0019] The first step: chemicals. Take 550 kg of licorice extract raw material and add it to the chemical pot, add 550 kg of pure water in a 1:1 weight ratio, heat to a slight boil to fully dissolve the licorice extract to obtain a solution, filter the solution through a 20-mesh screen, and then add alcohol Can.

[0020] The second step: alcohol dissolution. Adding licorice extract consumption 9 times the concentration of 85% ethanol 4950L to the ethanol solution tank, measure with alcohol meter, make ethanol content reach 65% in the feed liquid, then add the diatomite of 0.2 times weight ratio of licorice extract consumption 110kg, after stirring and mixing evenly, open the circulation valve, and extract the solution in the alcohol dissolution tank at room temperature for 90 minutes.

[0021] The third step: filter press. The above feed liquid is sent to a diaphragm filt...

Abstract

The invention provides a preparation method for licorice fluid extract. The method comprises the following steps: material dissolving; dissolving with alcohol; press filtration; squeezing; concentration; blending; and filling and sealing. Compared with a traditional ternary alcohol precipitation process, the preparation method for the licorice fluid extract provided by the invention has the following advantages: a production cycle is shortened to 6 d from original 12 d, production cost is greatly reduced, and the disadvantages of decrease and instability of a pH value in the traditional process are overcome through repeated adjusting of the pH value.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine extraction, and in particular relates to a preparation method of licorice liquid extract. Background technique [0002] Licorice liquid extract is a liquid extract obtained by extracting glycyrrhizic acid in licorice extract with alcohol. It is a palliative medicine and is often used in combination with phlegm-reducing and cough-relieving medicines. The traditional preparation method uses three alcohol precipitation processes, the production cycle is as long as 12 days, and the production cost remains high. And the licorice liquid extract produced by the traditional preparation method has the disadvantages that the pH value drops and is unstable. Contents of the invention [0003] The invention provides a preparation method of licorice fluid extract. Compared with the traditional three-time alcohol precipitation process, the production cycle is shortened from the original 1...
