Preparation method of edible Chinese mugwort extract

Abstract

The invention relates to a preparation method of an edible Chinese mugwort extract. The preparation method comprises the steps of step (1) thoroughly cleaning Chinese mugwort stems and leaves free from pathogen infestation, soaking the cleaned Chinese mugwort stems and leaves in a sodium chloride aqueous solution, and performing ultrasonic treatment and ozone sterilization and disinfection duringsoaking; step (2) immersing the cut-up Chinese mugwort stems and leaves in liquid nitrogen, performing scooping up, performing freeze-drying, putting small broken segments into a fine crushing machine, and performing crushing to obtain stem and leaf powder; step (3) putting the stem and leaf powder into a solvent, and performing soaking; step (4) placing the stem and leaf powder and the solvent inan extraction kettle to obtain a preliminary Chinese mugwort extract; and step (5) putting the preliminary Chinese mugwort extract in a distillation column, performing high-temperature distillation,enabling gas generated after distillation to flow out of the top of the distillation column, performing liquefaction on the gas through a condensing tube to obtain liquid, and enabling the liquid to enter a collecting tube so as to obtain the Chinese mugwort extract. According to the preparation method of the Chinese mugwort extract disclosed by the invention, loss of effective components in a Chinese mugwort extraction process can be effectively avoided, quality and yield of Chinese mugwort extracts are increased, and industrialized production is easy to realize.

Description

technical field [0001] The invention relates to the technical field of wormwood extracts, in particular to a preparation method of edible wormwood extracts. Background technique [0002] With the acceleration of people's life rhythm and the increasing pressure of work competition, slow sleep onset and insomnia have seriously troubled everyone. Among the Chinese population, 45.4% of people have sleep disorders. The traditional classic treatment method of Western medicine: taking diazepam , but it has many adverse reactions, such as: [0003] (1) Drowsiness, dizziness, fatigue, etc., large doses may cause ataxia and tremor; [0004] (2) Rarely have skin rash and leukopenia; [0005] (3) Individual patients experience excitement, multilingualism, sleep disturbance, and even hallucinations. After stopping the drug, the above symptoms disappeared quickly; [0006] (4) Long-term continuous drug use can cause dependence and addiction, and withdrawal symptoms may occur when the ...

AI Technical Summary

Problems solved by technology

[0006] (4) Long-term continuous drug use can lead to dependence and addiction, withdrawal symptoms may occur when the drug is stopped, manifested as agitation or depression

[0021] After research, it is found that the preparation methods of wormwood extracts currently on the market, especially the preparation methods of edible wormwood extracts, have relatively large defects, such as the extraction of essential oils has many impurities and the quality is not high

Secondly, the structure of the existing distillation extraction device is complex. Although high-temperature distillation is also used, it is relatively cumbersome to implement and has low efficiency.
