specific Embodiment approach 1

[0020] Specific embodiment 1: This embodiment provides a decolorization and debittering method in the production of inulin by the full-membrane method. The process is to pass the chicory water extract (hot melt extraction or cold pressing extraction) through an ultrafiltration membrane ( 20,000 molecular weight membrane) interception, remove 20,000 molecular weight non-inulin component macromolecules (including macromolecular pigments) to obtain a clear liquid; the clear liquid is pretreated by a nanofiltration membrane (500 molecular weight) to exclude most of the low molecular salt The material liquid is then adsorbed by the macroporous resin to remove the pigment and bitterin. After the conductivity value is qualified (the conductivity is less than 200S), it enters the next process for concentration and spray drying to obtain inulin (content 86% or more, moisture less than 4%) , The microorganism is below the national standard value).

specific Embodiment approach 2

[0021] Specific embodiment two: this embodiment is different from specific embodiment one in that when the macroporous resin has sufficient capacity, there is no need for membrane salt. When the resin capacity decreases and the conductivity is high, membrane protection is required. The specific process is as follows: Chicory water extract (hot melt extraction or cold pressing extraction) is intercepted by ultrafiltration membrane (20,000 molecular weight membrane), and 20,000 molecular weight non-inulin component macromolecules (including macromolecular pigments) are removed to obtain clear liquid; clear liquid After pretreatment with nanofiltration membrane (500 molecular weight), most of the low-molecular salt material liquid is removed, and then the pigment and picrine contained in the macroporous resin are adsorbed, and then most of the water and ion are removed by the nanofiltration membrane (300 molecular weight) After the salt is exchanged with the resin to exchange the p...

Abstract

The invention discloses a method for removing pigment and ichangin of inulin produced through a full-film technology. The method includes the following steps that first, a cichorium intybus water extracting solution is intercepted by an ultrafiltration membrane, macromolecules of non-inulin components are removed, and accordingly a clear solution is obtained; second, the ultrafiltration membrane clear solution is pretreated by a nanofiltration membrane, the content of salt in the solution is lowered, and the strong solution is qualified under the conditions that the electric conductivity is lower than 1000 S and the acidity PH value is 6.5-7; third, the feed solution pretreated by the nanofiltration membrane is subjected to decoloration and debitterizing treatment through macroporous resin, and the purposes that the solution is colorless and free of bitterness and the electric conductivity is lower than 200 S are achieved; fourth, the feed solution subjected to decoloration and debitterizing treatment through the macroporous resin is dehydrated and desalted through the nanofiltration membrane. According to the method, membrane method separation and macroporous resin absorption are reasonably combined, and the optimum decoloration and debitterizing effects are achieved on the inulin produced by cichorium intybus; compared with products in the same industry, the bitterness is the same, the color scale is lowest, pollution is minimum, and the solid inulin yield is highest and reaches 10%.

Description

Technical field [0001] The invention relates to a method for extracting natural plants to remove natural pigments and picrines possessed by plants. Background technique [0002] In the process of producing inulin by using chicory as raw material, the pigment and bitterin in the plant should be removed. The original production method is: the extraction liquid is subjected to a flocculation process to precipitate macromolecules and part of the pigment; the material liquid is then subjected to electrodialysis Most of the salt is removed, and then desalted by desalting resin; afterwards, the material liquid obtained by decolorizing by activated carbon and adsorbing picrine by the debittering resin is concentrated to remove most of the water and then goes to the next process for concentration and spray drying to obtain inulin. The disadvantage of this method is that calcium hydroxide and ferrous sulfate need to be added for flocculation and precipitation, and external salt is added to...
