Problems solved by technology

[0003] In the method of refining capsicum essence with macroporous resin, Chinese patents CN1392201A and CN101940289A use macroporous resin to separate capsicum essence, which has a large solvent consumption, complicated operation, and high yield. The rate is low, and it cannot be fully applied to the production of decolorized capsicum extract

Abstract

The invention relates to a process for preparing decolorized water-based capsicum oleoresin. The process comprises the following steps: (1) dissolving a crude capsicum oleoresin product into alcohols, stirring, dissolving and participating at certain temperature; (2) separating out clear liquid in the step (1), concentrating to be 1 / 5; (3) adding a certain amount of decolorizing resin to the concentrated liquor in the step (2) for decolorizing; (4) filtering, concentrating the filtrate, recovering a solvent, and desolventizing to be qualified, so as to obtain decolorized capsicum oleoresin extractum; and (5) adding a certain amount of emulsifier to the extractum, emulsifying and mixing into the decolorized water-based capsicum oleoresin with certain concentration. The decolorized water-based capsicum oleoresin produced by the process is strong in solubleness, low in color value, flavescent, transparent, and free of impurities or sediments; the application field of the capsicum oleoresin is expanded; and the capsaicin content of the decolorized water-based capsicum oleoresin produced by the method is 1%-18%.

Description

technical field [0001] The invention belongs to the field of natural pigment preparation, and in particular relates to a preparation process of decolorized water-based capsicum extract. Background technique [0002] At present, in the process of producing decolorized capsicum extract, activated carbon or diatomaceous earth, activated clay, hydrogen peroxide, etc. are mostly used for decolorization. However, the above methods exist, a large amount of capsanthin cannot be recovered, the solvent consumption is large, the decolorization effect is not good, the adsorbent cannot be recycled, and it is difficult to produce on a large scale. [0003] In the method of refining capsicum essence by using macroporous resin, Chinese patents CN1392201A and CN101940289A use macroporous resin to separate capsicum essence, but there are large solvent consumption, complicated operation and low yield, which cannot be fully applied to the production of decolorized capsicum essence.
