Abstract

The invention discloses a technique to use supercritical fluid technology to separate Zantho- xylum bungeanumí»s tingling-taste component. It crushes Zantho- xylum bungeanumí»s peel into powder, places in supercritical extraction pot and adds carrier, alcohol, to extract the component; and adjusts the separation pot to control parameters, to separate the component. It adopts CO2 as extraction solvent, has not pollution and can be used as raw material of food and drug.

Description

technical field [0001] The invention relates to a process for separating the numbing components of prickly ash, in particular to a process for separating the numbing components of prickly ash using supercritical fluid technology. Background technique [0002] Zanthoxylum bungeanum is a unique spice variety in my country. It has a long history of use in my country. It is one of the spice varieties often used in people's daily life and is a traditional seasoning variety. Zanthoxylum bungeanum is the only spicy variety among common seasonings. It is mellow and delicious, and it is an excellent seasoning. However, except for my country and a few Asian countries that are accustomed to this seasoning, most foreign countries do not recognize this spicy taste, which hinders the entry of Zanthoxylum bungeanum into the international market. At the same time, the spicy component of Zanthoxylum bungeanum is also a kind of pharmaceutical raw material, which has the functions of anesthes...
