Problems solved by technology

The operation steps of the organic solvent method are cumbersome, and the amount of organic solvent is large, so it is difficult to popularize and apply; the supercritical carbon dioxide fluid extraction method uses a solvent method to extract the crude capsicum essence, and then puts the crude capsicum essence into the extraction kettle in the supercritical device, and opens the extraction The circulation loop "extraction-separation-extraction" is used to extract and control the pressure of carbon dioxide to obtain capsaicin with high purity. However, this method has high requirements for equipment investment, safety and operation, and the production cost is also high, which is not conducive to production and application. Enzymatic extraction also has certain limitations, such as higher requirements on test conditions such as temperature, pH value and action time, and the types of applicable enzymes are also very limited, which restricts the popularization and use of this method

Abstract

The invention discloses a method for extracting capsaicin crystals from oleoresin capsicum. The method comprises the following steps that chilli powder is extracted with an aqueous alkaline solution in a single-stage continuous countercurrent ultrasonic extraction machine, wherein the aqueous alkaline solution is prepared from sodium chloride, sodium acetate, sodium hydroxide and beta-cyclodextrin; filtrate obtained through filtering separation is processed through the steps of concentration, ethanol extraction, reduced pressure distillation, petroleum ether low-temperature recystalization and the like, and then the high-purity needle-shaped capsaicin crystals are obtained. According to the method, a continuous countercurrent and ultrasonic extraction technique, a micro-cutting interaction technique and the like are combined on the basis of a common solvent method, the extraction time is shortened, the solvent using amount is decreased, the recycle rate and the purity of the capsaicin crystals can be effectively increased, the whole operation process is easy and convenient, the requirements for the reaction condition and production equipment are low, and the method is a capsaicin crystal extraction technology which is suitable for industrialized popularization.

Description

technical field [0001] The invention belongs to the technical field of capsaicin extraction, and in particular relates to a method for extracting capsaicin crystals from capsicum essence. Background technique [0002] Capsaicin, also known as capsaicin, capsaicin, etc., generally has the highest content in the peptide chamber tissue (seed part) and diaphragm tissue in the fruit, and the middle part of the peel, and is the main chemical substance that causes the spicy taste of pepper. This spicy component was first isolated from pepper fruit by Thres (1876). Later, some scholars analyzed its chemical composition in detail and found that the spicy component in pepper is composed of a series of homologues: capsaicin, Dihydrocapsaicin family, homocapsaicin family, nordihydrocapsaicin family, p-methyl capsaicin family, p-methyl capsaicin saturated chain hydrocarbon family, p-methyl capsaicin ene chain family, etc., among which capsaicin family Mainly. Capsaicin products are wid...
