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.
