Problems solved by technology

[0002] Most of the existing technologies use single-phase or two-phase solvent extraction to separate capsaicin and capsanthin products in capsicum oleoresin. This extraction method has low efficiency and incomplete extraction, and the obtained products often contain various impurities.
From the perspective of production efficiency, this method is inefficient, time-consuming and labor-intensive, and the labor intensity of workers is high. The organic solvent used in the production process is easy to leak, which will cause environmental pollution when the production safety is seriously endangered.
The capsanthin product produced in the prior art will be partially decomposed, and the produced capsaicin product and capsanthin product are not stable in quality

Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. Accompanying drawing is a simplified process flow chart, only schematically illustrates the basic process flow of the present invention.

[0014] Specific implementation one: please refer to figure 1 , a method for extracting capsaicin and capsanthin from capsicum oleoresin, the steps comprising:

[0015] (1), capsicum oleoresin 11 is made into preliminary dilution solution with diluent n-hexane in batching tank-1, wherein the volume ratio of capsicum oleoresin and diluent n-hexane is 1: 5;

[0016] (2), adding extractant methanol aqueous solution in batching tank two 2, the initial dilution solution prepared in step 1 and extractant methanol aqueous solution are transported in the cooler 3 according to the volume ratio 1:5;

[0017] (3), control the temperature of the cooling solution coming out of the cooling machine 3 between 25°C, send the cooling solution coming out...

Abstract

The invention relates to a method for extracting capsaicin and capsanthin from capsicum oleoresin. The method adopts a low temperature efficient dynamic reflux continuous forward single stage or forward and reverse multistage extraction manner, thus having good extraction effect and high efficiency; the method uses less solvent, thus saving labor cost, reducing energy consumption, and improving production efficiency. A negative pressure steam concentrator used in the method can reduce the temperature of steam to be less than 65DEG C, so that the capsanthin product is guaranteed not to be degraded due to overhigh temperature, and a large amount of heat resource is guaranteed to be used for heating so as to improve the efficiency and the use ratio of the heat resource. By adopting airtight continuous mechanical operation, liquid-liquid extraction and chromatographic separation, the method obtains over 98% of s high contentcolorless capsaicin and more than 480E of non-spicy capsanthin, and also improves labor efficiency, the use ratios of the capsaicin and capsanthin in the raw material are over 98%, and environmental pollution is also avoided.

Description

technical field [0001] The invention relates to a method for extracting capsaicin and capsanthin from capsicum oleoresin. Background technique [0002] The prior art mostly uses single-phase or two-phase solvent extraction to separate capsaicin and capsanthin products in capsicum oleoresin. This extraction method has low efficiency and incomplete extraction, and the obtained products often contain various impurities. From the perspective of production efficiency, this method is inefficient, time-consuming and labor-intensive, and the labor intensity of workers is high. The organic solvent used in the production process is easy to leak, which will cause environmental pollution when the production safety is seriously endangered. The capsanthin product produced in the prior art may partially decompose, and the produced capsaicin product and capsanthin product are unstable in dissolved quality. [0003] Therefore, in order to solve the above technical problems, it is necessary ...
