Method of reducing use amount of activated carbon in production processes of high fructose corn syrup

Abstract

The present invention belongs to the field of food processing and discloses a method of reducing a use amount of activated carbon in production processes of high fructose corn syrup. A method of reducing the use amount of the activated carbon in the production processes of the high fructose corn syrup is as follows: a cation resin ion exchange column is used to treat isomerized fructose corn syrup, circulating water is added to treat the fructose corn syrup, in every 10 BV of a material discharge volume, 50 ml of samples are taken, an instantaneous pH of discharged materials is measured, then the isomerized fructose corn syrup and the taken treated samplesare mixed until a pH of the sample is 5, and a mixed solution is decolorized. By increasing technological processes to conduct the decoloration of the high fructose corn syrup, a decoloration effect is improved, the use amount of the activated carbon in the decoloration working section is lowered by 50% or more, a production cost is reduced, an energy consumption is lowered, and the production technology of the high fructose corn syrup is more optimized.

Description

technical field [0001] The invention belongs to the field of food processing and discloses a method for reducing the consumption of activated carbon in the production process of fructose syrup. Background technique [0002] High fructose syrup is a common material in food processing. The production of high fructose syrup requires treatment processes such as pH adjustment and decolorization. The fructose syrup from the fructose syrup isomerization column is directly added to the fructose syrup decolorization tank after being treated by the fructose syrup isomerization column, and the fructose syrup is decolorized by using the activated carbon in the decolorization tank. The decolorization effect is based on The color value of the syrup is tested for comparison. The amount of activated carbon used for decolorization of the material is three thousandths of the dry basis of the material (the denominator is called the dry basis with the unchanging part of the mass), but the decol...

The decolorization effect is based on The color value of the syrup is tested for comparison. The amount of activated carbon used for decolorization of the material is three thousandths of the dry basis of the material (the denominator is called the dry basis with the unchanging part of the mass), but the decolorization effect is not good. After structuring, the color generally becomes darker, which does not meet the requirements of the decolorization process, and the amount of activated carbon is relatively large
