Preparation process for extracting active ingredient of natural plant by supersonic

Abstract

The invention discloses a preparation process for extracting active ingredient of natural plant by supersonic, which comprises the following steps: firstly, cleaning and removing dust; secondly, crushing; thirdly, steeping: placing the crushed natural plant raw material to be extracted into a material mixing tank with a mixer for continuously mixing, adding steeping fluid in the natural plant rawmaterial to be extracted in the material mixing tank and obtaining material mixture after mixing and stirring; fourthly, supersonically extracting: passing the material mixture circularly continuously through the inner part of a supersonic extraction device by a circulation pipe between the material mixing tank and the supersonic extraction device and performing the continuous, circulated and supersonic extraction; fifthly, filtering, sixthly, reducing and concentrating. The invention saves time and labor, can obviously improve the product quality and the product yield, has short extraction time, high extraction efficiency, and low temperature during the extraction without heating, and prevents effective ingredient being damaged when heating at high temperature.

Description

Technical field [0001] The invention belongs to the technical field of extraction of natural plant active ingredients, and in particular relates to a preparation process for ultrasonic extraction of natural plant active ingredients suitable for the field of seasoning product preparation. Background technique [0002] Nowadays, the extraction method for the effective ingredients of natural plants is mainly the classic solvent extraction method. The principle is to select a volume with high solubility for the active ingredients and low solubility for impurities according to the different solubility of the ingredients in natural plants in different solvents. Dissolve the active ingredients from the plant tissues. The commonly used methods in the solvent extraction method are: dipping method, percolation method, decoction method, reflux extraction method and continuous reflux extraction method. At present, industrial production mainly adopts reflux extraction method and continuous re...

AI Technical Summary

Problems solved by technology

At present, industrial production mainly adopts reflux extraction method and continuous reflux extraction method, but these two extraction methods still have some shortcomings and deficiencies in actual industrial production

[0003] Among them, the shortcomings and deficiencies of the reflux extraction method are as follows: 1. The extraction efficiency is low, and the solvent needs to be renewed two to three times for each batch of extraction; 2. The solvent is used in a large amount, and the operation process is cumbersome, and it takes a lot of work when boiling; 3. The total extraction time is long, the temperature is high, some active ingredients are lost or other chemical reactions occur, which significantly affects the product quality

The disadvantages and deficiencies of the continuous reflux extraction method are as follows: the extraction process takes a long time, generally 5 to 8 hours, and the extraction temperature is relatively high, so it will cause some thermally unstable and easily changeable components in natural plants, that is, heat sensitivity. The loss of active ingredients affects the flavor quality of the product
