Process for decolorizing sweetening agent mother liquor for preparing electronic atomized liquid

Abstract

The invention relates to the field of electronic atomized liquids, and particularly discloses a process for decolorizing a sweetening agent mother liquor for preparing an electronic atomized liquid. The process comprises the following steps: adding modified macroporous adsorption resin into an acesulfame potassium mother solution according to a weight ratio of the acesulfame potassium mother solution to the modified macroporous adsorption resin being 100: 4, stirring, adding modified activated carbon according to a weight ratio of the acesulfame potassium mother solution to the modified activated carbon being 100: 5, stirring to obtain a crude product, and filtering the crude product to obtain a finished product; modifying the macroporous adsorption resin with an anionic polyacrylamide solution to obtain modified macroporous adsorption resin;and modifying the activated carbon with an ammonia water solution to prepare modified activated carbon. The process has the advantages that pigments, colloids and suspended impurities in the sweetening agent mother liquor are efficiently removed, a decolorizing agent is conveniently filtered out, and the color and the purity of a product are guaranteed.

Description

technical field [0001] The present application relates to the field of electronic atomization liquid, and more specifically, it relates to a process for decolorizing the sweetener mother liquor used in the preparation of electronic atomization liquid. Background technique [0002] The electronic atomizing liquid mainly contains water, propylene glycol, glycerin, nicotine and flavoring agents. As one of the flavoring agents, the sweetener can adjust the taste of the electronic atomizing liquid and make the electronic atomizing liquid have a sweet taste. [0003] At present, the commonly used sweeteners mainly include acesulfame-K or sucralose, and the mother liquor of acesulfame-K or sucralose contains a certain amount of acesulfame-K or sucralose, suspended solids and pigments, etc. Brown, if not recycled, the production cost of the sweetener will increase, and the direct use will affect the quality of the product; the sugar content in the mother liquor generally reaches 10%...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used sweeteners mainly include acesulfame-K or sucralose, and the mother liquor of acesulfame-K or sucralose contains a certain amount of acesulfame-K or sucralose, suspended solids and pigments, etc. Brown, if not recycled, the production cost of the sweetener will increase, and the direct use will affect the quality of the product; the sugar content in the mother liquor generally reaches 10%-35%, and the decolorization treatment of the mother liquor can effectively change the color of the mother liquor. It can also remove most of the colloids and suspended impurities, thereby improving the utilization rate of the mother liquor

[0004] Generally, activated carbon adsorption is used for decolorization treatment, but activated carbon decolorization is generally performed intermittently, which is prone to leakage of activated carbon, resulting in incomplete decolorization; and after decolorization, it is prone to problems that the filtration is not fine enough, affecting the color and purity of the product
