Problems solved by technology

For example, the combination of sulfurous method and phosphorus floatation method can effectively reduce the sulfur content in sugar products, but due to the lengthening of the process flow, it will cause additional loss of sucrose and increase in color value; and the development of efficient decolorizers is very important for the sulfurous method. Effective supplementation or improvement of the clarification process is also one of the reform directions of the sugar clarification process

Abstract

The invention relates to a sugar juice compound decolorizing agent and a sugar juice decolorization method. The sugar juice compound decolorizing agent is an H2O2-Vc compound reagent composed of H2O2and vitamin C in a mass ratio of 0.01-10. The sugar juice decolorization method includes: using the H2O2-Vc compound reagent for decolorization treatment on sugar juice, which is mixed juice, clear juice, syrup or / and massecuite, wherein the adding amount of the H2O2-Vc compound reagent and the corresponding sugar juice are in a mass ratio of 10*10<-6>-2*10<-3> in the decolorization process. The method provided by the invention can greatly reduce the color value of sugar juice and sulfur dioxide residual, can effectively lower the content of colored matters and sulfur residue in the final white granulated sugar finished product, at the same time can enhance the purity of white granulated sugar, thus improving the quality of the white granulated sugar finished product; and on the other hand, the process is simple, has no need for change of the original technological process, also in low in investment and utilization cost, and can significantly improve the economic benefits of sugar factories.

Description

technical field [0001] The invention relates to a compound decolorizing agent for sugar juice and a method for decolorizing sugar juice. Background technique [0002] The color value of white granulated sugar is the most important and most technically difficult quality index of white granulated sugar. There are many and complex types of colored substances in sugar products, including two types of colored substances originally contained in sugarcane and those produced during the production process. The original pigments contained in sugarcane are mainly fat-soluble and water-soluble. The former coexists with lipids in sugarcane juice and is basically insoluble in water. Most of them can be removed when heated. Water-soluble pigments are mainly various polyphenols, which are the main reason for coloring white granulated sugar and various sugar products. On the other hand, in the sugar production process, in addition to clarification treatment to remove some colored substance...
