Method for producing decolorized aqueous chilli extract

Abstract

The invention relates to a method for producing decolorized aqueous chilli extract. The method comprises the following steps: (1) the chilli extract crude product is dissolved in alcohol, is stirred to be dissolved at a certain temperature and is settled; (2) the clear liquid which is obtained in (1) is separated out, and is concentrated to 1 / 5; (3) a certain amount of decolorizing resin is added into the concentrated solution which is obtained in (2) for decolorizing; (4) filtration is carried out for concentrating the filtrate and recovering the solvent, desolvation is carried out until reaching the standard, so that the decolorized chilli extract concrete is obtained; and (5) the concrete is added with a certain amount of emulsifier to be emulsified and mixed into the decolorized aqueous chilli extract with a certain concentration. The decolorized aqueous chilli extract which is produced by the method has strong dissolubility, is low in color value, is light yellow and transparent, and does not have impurities and sediments, so that the application field of chilli extract is broadened. The decolorized aqueous chilli extract which is produced by the method has the capsaicin content of 1-20%.

Description

technical field [0001] This article relates to a production method 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 for refining capsicum essence by using macroporous resin, Chinese patents CN1392201A and CN101940289A utilize macroporous resin to separate capsicum essence, but there is a large solvent consumption, complicated operation and low yield, which cannot be fully applied to the production of decolorized capsicum essence. Contents of the invention [0004] The purpose of this invention is to provid...
