Embodiment 1

[0018] A way to prevent CO 2 The method for supercritical extraction of Zanthoxylum bungeanum oleoresin crystallization comprises the following steps:

[0019] (1) Crush the prickly ash material to 40 meshes, then at 40°C, 35Mpa, CO 2 Extract at a flow rate of 12mL / min for 3 hours to obtain a semi-finished product of Zanthoxylum oleoresin, then conduct molecular distillation at 70°C to remove water from the semi-finished product of Zanthoxylum oleoresin, and obtain Zanthoxylum oleoresin at a temperature of 60°C after water removal;

[0020] (2) Carry out tubular centrifugation on the Zanthoxylum bungeanum oleoresin whose temperature after water removal is 60° C., the centrifugal speed is 16000 r / min, collect the outlet feed liquid, and obtain high-purity Zanthoxylum bungeanum oleoresin;

[0021] (3) Put the high-purity Zanthoxylum bungeanum oleoresin in a closed tank, first take out the air in the closed tank to form a negative pressure in the closed tank, stop pumping when t...

Abstract

The invention discloses a method for preventing crystallization of zanthoxylum oil resin obtained by CO2 supercritical extraction. The method comprises the following steps: distilling zanthoxylum oil resin obtained by CO2 supercritical extraction to remove water; performing tubular centrifugation on the dehydrated zanthoxylum oil resin, and collecting an outlet material liquid to obtain high-purity zanthoxylum oil resin; placing the high-purity zanthoxylum oil resin in a closed tank body, pumping air in the closed tank body out firstly, forming negative pressure in the closed tank body, then recovering normal pressure instantly, repeating the operation for 1-2 times, and obtaining the high-purity zanthoxylum oil resin. The method can effectively solve the problem that the zanthoxylum oil resin treated by the existing method is short in storage time.

Description

technical field [0001] The invention relates to the technical field of pepper oil extraction, in particular to a method for preventing CO 2 A method for supercritical extraction of Zanthoxylum bungeanum oleoresin crystallization. Background technique [0002] Most of the current Zanthoxylum bungeanum oil is extracted by steam distillation, CO 2 Supercritical extraction, solvent extraction, pressing, subcritical extraction, etc. The steam distillation method is suitable for extracting the aromatic components of essential oils, and the extracted essential oils have no taste. Both solvent extraction and subcritical extraction have solvent residues, and the extraction by pressing is incomplete, which easily leads to waste of raw materials. Most manufacturers now use CO 2 Supercritical extraction does not require high conditions such as temperature and pressure, and there is no solvent residue, good fragrance, and relatively complete extraction. But the Zanthoxylum bungeanum...
