Problems solved by technology

The patent application number 201210309645.4 discloses a preparation method of high-purity anthocyanin. In order to avoid the use of various chromatographic columns, the method uses prickly ash oleoresin as raw material, adds a polar solvent to extract the solid, and then Add n-hexane to extract, and then use n-hexane to wash to obtain ananthoxylin crystals. This method claims that the purity of ananthantham can reach more than 90%. The composition requirements of the raw materials are unknown, and the operation process still has certain technical difficulties, which need to be further studied; and solvent extraction makes the finished product prone to solvent residues, which poses a safety hazard
[0004] At present, there are some studies on the preparation method combining supercritical extraction and molecular distillation, which are mainly used for the research of volatile components such as essential oils, but there is basically no research on the purification of flavor substances.

[0023] The preparation method of high-purity xanthanin of the present invention is as follows:

[0024] ① Raw material pretreatment: use the Zanthoxylum oleoresin extracted by supercritical as raw material, heat until there are no insoluble solid particles, the heating temperature is 60-70°C, and the heating time is 10-15min; the Zanthoxylum oleoresin component includes Zanthoxylum aromatic oil , linalool, limonene, pepper amide substances;

[0025] ② Evaporation: Zanthoxylum oleoresin enters the evaporator H1 at a feed rate of 80-100ml / h, and distributes it continuously and evenly on the heating surface through the feed liquid distributor, and then the film wiper scrapes the feed liquid into a liquid film , the temperature of the heating surface is 80-95°C, the frequency of the wiper is 50HZ, the thickness of the liquid film is 0.01-0.02cm, and then the light component and the heavy component are separated under the vacuum degree of 40-50Pa;

[0026] ③Molecular distillation:...

Abstract

The invention discloses a preparing method for high-purity sanshoamides. The preparation method comprises the following steps: a supercritical carbon dioxide extraction technology and a molecular distillation technology are combined, zanthoxylum oil resin which is obtained through supercritical extraction is used as a raw material, pre-treatment, and evaporation and molecular distillation are performed on the raw material to prepare the sanshoamides. The utilization rate of the raw material in the preparation method is high, the content of the sanshoamides in the obtained sanshoamides products is 720mg / g-850mg / g, and the purity of the products is high.

Description

technical field [0001] The invention belongs to the field of extraction technology of porchepin, and in particular relates to a preparation method of high-purity porchepin. Background technique [0002] Zanthoxylum bungeanum is a traditional seasoning in our country. When using Zanthoxylum bungeanum, the numbing substance of Zanthoxylum bungeanum contained in Zanthoxylum bungeanum is mainly used. At present, pepper resources at home and abroad are abundant but processing and utilization technology is lacking. In daily use, the method of oil immersion is generally used to extract peppercornin. This method has a low content of peppercornin, generally 3-5mg / g. The utilization of raw peppercorn The rate is low and the waste is serious. There are also studies using supercritical carbon dioxide to extract and separate the anthanthin. For example, the patent application number 200910263947.0 discloses a method for extracting the essential oil and the anthanthin from the pepper. K...
