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.

Example Embodiment

[0017] Example 1

[0018] A method of preventing CO 2 Pepper oil supercritical extraction method of crystallization of the resin, comprising the steps of:

[0019] (1) The material crushed pepper 40 mesh, and then at 40 ℃, 35Mpa, CO 2 The flow rate of extraction 3h 12mL / min conditions to prepare a semi pepper oleoresin, pepper oleoresin and then at 70 ℃ for semi molecular distilled water, in addition to the water to give a resin temperature of 60 deg.] C of pepper oil;

[0020] (2) except that the temperature of the pepper oleoresin after water is 60 ℃ were centrifuged tube, centrifugal rotation 16000r / min, collecting outlet feed solution, to give high-purity pepper oil resin;

[0021] (3) High purity pepper oil resin is placed in a sealed tank, to deprived of air sealed in the tank, the negative pressure in the sealed tank, pumping is stopped when the negative pressure reaches -0.05 MPa, and instant recovery atmospheric pressure, the above-described operation is repeated twice, pepper oil resin can be treated for dispensing storage.

Example Embodiment

[0022] Example 2

[0023] A method of preventing CO 2 Pepper oil supercritical extraction method of crystallization of the resin, comprising the steps of:

[0024] (1) The material crushed pepper 30 mesh, and then at 45 ℃, 30Mpa, CO 2 4h under extraction flow 13mL / min conditions to prepare a semi pepper oleoresin, pepper oleoresin semifinished then at 72 deg.] C conditions of molecular distillation for removal of water, in addition to the water to give a temperature of 62 ℃ pepper oleoresin;

[0025] (2) except that the temperature of the pepper oleoresin after water is 62 ℃ centrifuge tube, centrifuge speed is 16000r / min, collecting outlet feed solution, to give high-purity pepper oil resin;

[0026] (3) High purity pepper oil resin is placed in a sealed tank, to deprived of air sealed in the tank, the negative pressure in the sealed tank, pumping is stopped when the negative pressure reaches -0.05 MPa, and instant recovery atmospheric pressure, the above-described operation is repeated once to the pepper oleoresin processed for dispensing storage.
