Abstract
The present invention relates to a system for reducing a content of 5-hydroxymethylfurfural in a high fructose syrup, including an ion exchange positive column and an ion exchange negative column for performing cation and anion removals in sequence for an F42 high fructose syrup obtained by performing isomerization and first decolorization, a heat exchanger for performing heat exchange and temperature reduction for an F55 high fructose syrup obtained by performing concentration, chromatographic separation, blending and second decolorization in sequence for the F42 high fructose syrup subjected to ion exchange, a mixed bed column for performing purification for the heat-exchanged F55 high fructose syrup, and an evaporation tank for performing concentration for the F55 high fructose syrup subjected to mixed bed treatment. The present invention further provides a method of reducing a content of 5-hydroxymethylfurfural in a high fructose syrup. In the present invention, optimization is performed for ion exchange and operation modes and parameters of the mixed bed such that the HMF content in the high fructose syrup product is reduced in a case of ensuring the quality of the high fructo…
