Abstract

The invention discloses an extraction process for improving the recovery rate of prickly ash, and relates to a method for extracting food spices. The specific method includes: (1) Zanthoxylum bungeanum pretreatment: compressing Zanthoxylum bungeanum raw materials into tablets, the thickness of which is 0.1-0.5mm; 2) Supercritical CO 2 Fluid extraction: Put the pepper flakes into the extraction tank, when the pressure of the extraction tank rises to 30-35MPa, and the extraction temperature is 45-55°C, feed supercritical CO 2 At the same time, the entraining agent is introduced into the entraining agent, extracted for 2-3 hours, and the extract is obtained; (3) Separation: the extract enters the separation tank for separation, the separation pressure is 6-8MPa, and the separation temperature is 50-55°C to obtain Zanthoxylum bungeanum crude oil and gaseous CO 2 (4) Separating the entrainer from the extracted Zanthoxylum bungeanum crude oil, and finally obtaining the oleoresin containing pianopianin. The process has high recovery rate and simple process.

Description

technical field [0001] The invention relates to a method for extracting food spices, in particular to an extraction process for improving the recovery rate of xanthanin. Background technique [0002] Zanthoxylum bungeanum is a commonly used condiment. In daily use, it is generally crushed or used directly. In this way, the numb substances in Zanthoxylum bungeanum cannot be effectively utilized. The method of supercritical carbon dioxide extraction is currently the most efficient production and extraction method for extracting the numbing substances of peppercorns, but the recovery rate of pepperanthin is generally about 60% and 30% when the traditional supercritical carbon dioxide extraction method is used to extract the numbing substances of peppercorns Left and right cannabinoids have not been effectively extracted, resulting in waste of prickly ash raw materials. [0003] Chinese patent literature (authorized notification number CN1220450C) discloses a process for separa...
