Problems solved by technology

However, molecular distillation equipment requires continuous production, and the equipment has low compatibility. It can only be used for liquid-liquid separation, and other processing operations (such as extraction and separation of solid substances) cannot be realized.
It is technically difficult to use supercritical equipment to deoil and process Zanthoxylum bungeanum oleoresin, which has not been reported yet.

Abstract

The invention discloses a fresh pericarpium zanthoxyli oleoresin separation and purification process which comprises the following steps: after harvesting fresh pericarpium zanthoxyli, carrying out cold pressing within two hours to obtain fresh pericarpium zanthoxyli oleoresin, carrying out countercurrent extraction separation on the fresh pericarpium zanthoxyli oleoresin through a liquid substance extraction and separation unit of a supercritical CO2 fluid dynamic countercurrent extraction and separation system, and after the countercurrent extraction separation is completed, obtaining fresh pericarpium zanthoxyli resin from the extraction unit, and obtaining fresh pericarpium zanthoxyli essential oil through a separation unit. The extraction separation process is as follows: the feeding rate is 40kg / h, the CO2 flow rate is 600L / h, the extraction temperature is 45 DEG C, and the extraction pressure is 20MPa; the separation I temperature is 40 DEG C, the separation I pressure is 7.5 MPa, the separation II temperature is 55 DEG C, and the separation II pressure is 4-6 MPa; the total yield of the oleoresin product reaches 98.74%-99.17%, and the separation efficiency of volatile oil reaches 94.00%-99.24%; the volatile oil content of the obtained essential oil can reach 101.94-128.93 ml / 100g; the content of amide substances in the obtained resin can reach 575.22 mg / g to 645.99 mg / g, and the content of the amide substances is increased to 79.08% to 98.25%. According to the process disclosed by the invention, the fresh pericarpium zanthoxyli essential oil with high volatile oil content and the fresh pericarpium zanthoxyli resin with a high amide substance content can be obtained, and the purification effect of the two products is remarkable.

Description

technical field [0001] The invention belongs to the technical field of biochemical products, discloses a fresh pepper oleoresin separation and purification process, specifically discloses a process using supercritical CO 2 A process for fluid dynamic countercurrent extraction and separation of liquid substances, and fresh pepper essential oil and fresh pepper resin prepared by the process. Background technique [0002] Zanthoxylum bungeanum is a condiment unique to my country and rich in resources. At present, there are many domestic research reports on the flavor characteristics and flavor substances extraction of Zanthoxylum bungeanum, but the extraction is limited to steam distillation, organic solvent (ethanol, acetone, etc.) extraction, etc. The steam distillation method can only extract the volatile oil with low boiling point in Zanthoxylum bungeanum, and the organic solvent extraction method has the disadvantages of high impurity content, large loss of flavor compone...
