Problems solved by technology

At present, the common method of extracting and separating ceramide from konjac powder is organic solvent extraction and separation method, which has the disadvantages of large solvent consumption, low extraction efficiency, long time-consuming, unstable active ingredients when heated, etc., making it difficult to large-scale Industrial production
Moreover, some toxic organic solvents are used in the extraction and separation process. The evaporation of organic solvents consumes a lot of energy, which is not environmentally friendly, and organic solvent residues in the product are inevitable.

Abstract

The invention belongs to the field of processes for extracting plant effective components and discloses a method for extracting and separating ceramide in konjac flying powder. According to the invention, an ultrasonic technology is utilized to carry out primary processing, so as to separate the ceramide from raw material cells in short time, extraction time is short, damage to effective ingredients, which is caused by high temperature heating, is avoided, and an extraction rate is improved for extraction and separation in the next step; then the characteristic of selective dissolving capacity of carbon dioxide in a super-critical state is utilized to carry out secondary extraction, refining and separation on different polar materials. The method has the advantages of low operating temperature, good selectivity, no damage to effective ingredient structures, capability of perfectly storing active ingredients of natural plants and the like, and enables the ceramide in the konjac flying powder to be efficiently extracted and separated out; compared with the prior art, content of the ceramide is higher and the konjac flying powder is more pure.

Description

technical field [0001] The invention belongs to the field of extraction technology of plant effective components, and in particular relates to an extraction and separation method of ceramide in konjac powder. Background technique [0002] Konjac (Amorfhophallus Konjac) belongs to the phylum Angiosperms, the class Monocotyledons, the family Araceae, and the genus Konjac. It is a perennial herbaceous plant with bulbs. Contains a large amount of dietary fiber, multivitamins, trace elements, amino acids and other active ingredients. It is a natural plant raw material for both medicine and food. Stomach and other functions. Ceramide is a kind of biologically active substance widely present in animal and plant cells, which is formed by condensation of long-chain sphingosine and fatty acid through amide bond. In recent years, ceramides have become important functional ingredients of emerging medical and health products, food and cosmetics, especially their high-efficiency moistur...
