Preparation technology of discolored aqueous chilli extract

Abstract

The invention relates to a production technology of discolored aqueous chilli extract. The production technology comprises the following steps: step one, dissolving a crude product of chilli extract into alcohol, stirring to dissolve the crude product at a certain temperature, and then carrying out settlement; step two, collecting supernate obtained in the step one, and condensing the supernate until one fifth of the supernate is left; step three, adding a certain amount of discoloring resin into the concentrated supernate obtained in the step two to discolor the supernate; step four, filtering the concentrated supernate, condensing the filtrate, recovering the solvent, desolventizing the concentrated supernate to obtain qualified discolored chilli extract; step five, adding a certain amount of emulsifying agent into the chilli extract to carry out emulsification, and blending to obtain discolored aqueous chilli extract with a certain concentration. The produced discolored aqueous chilli extract has the advantages of high solubility, low color value, and no impurity or precipitate, has a light yellow color, and is transparent. The application range of chilli extract is enlarged. The capsaicin content of the produced discolored aqueous chilli extract is 1 to 18%.

Description

technical field [0001] The invention belongs to the field of preparation of natural pigments, and in particular relates to a preparation process of decolorized water-based capsaicin. Background technique [0002] In the current process for producing decolorized capsaicin, activated carbon or diatomaceous earth, activated clay, hydrogen peroxide, etc. are often used for decolorization. But the above method exists, 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 large-scale industrial production. [0003] In the method of using macroporous resin to purify capsicum essence, Chinese patents CN1392201A and CN101940289A utilize macroporous resin to separate capsicum essence, which has large solvent consumption, complicated operation and low yield, which cannot be fully applied to the production of decolorized capsicum essence.
