AI Technical Summary

Technical Problem

In existing technologies, when extracting traditional Chinese medicine and food from the same source, it is difficult to take into account all the various components. The coordination of the liquid phase system is insufficient, which leads to problems such as inconsistent release of components, turbidity and sedimentation. Moreover, the existing process fails to effectively utilize the synergistic relationship between raw materials.

Method used

The raw materials from group A were used for two-stage extraction to form liquid A1 and liquid A2. Liquid A2 was used in the main extraction stages of groups B and C. Combined with carbon dioxide pressurization-depressurization circulation and ethanol-water solution ratio control, fractional extraction and diversion were carried out. Finally, the extraction environment was optimized by ethanol backflushing and A1 liquid backfilling.

Benefits of technology

It achieves coordinated release of various components, reduces the risk of turbidity and sedimentation of the extract, and improves the overall coordination and extraction effect of the liquid phase system.

Abstract

The invention relates to the technical field of medicinal and edible extraction, and discloses a synergistic preparation method of a medicinal and edible composite extract.The method comprises the steps that raw materials are divided into an endogenous conditioning group A, a hydrophilic skeleton group B and a function enhancing group C; the method comprises the following steps: firstly, carrying out two-stage extraction on the group A to respectively obtain a liquid A1 and a liquid A2, with the liquid A1 being enriched with aromatic micromolecules and part of weak fat-soluble active components and the liquid A2 being enriched with organic acids and hydrophilic regulation components; the A2 liquid is used as an endogenous conditioning liquid of the main extraction stages of the group B and the group C for collaborative extraction; then, the obtained composite main extracting solution is subjected to ethanol backswing purification, the A1 solution is added after dealcoholization, reversed-order backfilling is conducted, and the medicinal and edible homologous composite extract is obtained. The coordination and liquid phase stability of a composite extraction system are improved by combining graded extraction, split-flow use, endogenous tempering and back-section backfilling.
