Method for extracting xanthoxylin and sanshoamides from pricklyash peel

Abstract

The invention relates to a process for extracting xanthoxylin and sanshoamides through supercritical carbon dioxide. Firstly, the pricklyash peels are crushed and squashed into pieces, the squashed pricklyash peels are loaded in a supercritical extraction reactor for extraction, the extraction solvent is food-grade carbon dioxide, the extraction liquid sequentially enters a separation reactor I and a separation reactor II for separation, the pressure of the separation reactor I is 6-7 MPa, the temperature thereof is 25-32 DEG C and the time is 20-40 min; the pressure of the separation reactor II is 5-6 MPa, the temperature thereof is 22-26 DEG C and the time is 30-50 min; the products of the separation reactor I and the separation reactor II are respectively collected, the product of the separation reactor I is dehydrated and refined to prepare the sanshoamides, and the product of the separation reactor II is xanthoxylin; the sanshoamides, xanthoxylin and food oil are blended according to weight ratio of 1:1:30-100 to obtain supercritical pepper oil which can be used as flavoring oil for high-grade dinning industry.

Description

technical field [0001] The invention relates to a process for extracting prickly ash essential oil and pricklycannin by supercritical carbon dioxide. Background technique [0002] Zanthoxylum bungeanum is the fruit of the Rutaceae shrub or tree Zanthoxylum bungeanum. It has a unique strong aroma and is currently mainly used as a food seasoning spice. Zanthoxylum bungeanum also has a certain effect in traditional Chinese medicine. It is warm in nature, pungent in taste, warms the middle and relieves pain, kills insects and relieves itching. For epigastric cold pain, vomiting and diarrhea, worm accumulation abdominal pain, ascariasis; external treatment of eczema itching. In addition, there are other uses. "Shen Nong's Materia Medica Notes" records: "It was first produced in Qin." It was originally wild. Zanthoxylum bungeanum is spherical in shape, and the skin of the pepper is reddish in color, and turns black after drying. There are tortoise cracks and the top is cracke...

AI Technical Summary

Problems solved by technology

Pepper oil with better taste can be obtained through extraction of vegetable oil, but the extraction of active ingredients is incomplete and the waste is serious

Solvent extraction products have solvent residues, the appearance of the product is not good, and it is difficult to dissolve in oil

At present, there is no standard product of Zanthoxylum bungeanum in the market, which makes the accurate quantification of Zanthoxylum bungeanum components difficult. These are problems that need to be solved urgently in the development of the industry.
