摘要： 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 fructose syrup product, thus improving the quality of the high fructose syrup product.

摘要： The present invention provides a system for recovering protein in a production process of an ultrahigh maltose syrup, including a saccharification tank, an enzyme preparation tank, a first plate heat exchanger, a second plate heat exchanger, a plate and frame filter, a buffer tank and a rotary drum filter. The present invention further provides a method of recovering protein by using the system. After the sugar liquid in the saccharification tank is stood, the protein floats at the upper part of the saccharification tank and the lower liquid is clear and transparent and thus the sugar liquid can be directly filtered. When the saccharification tank is discharged, the lower liquid is firstly discharged with the remaining liquid being bottoms containing protein. During a production process, enzymatic hydrolysis is performed for the sugar liquid containing protein before filtration to improve the filtration effect of the sugar liquid. Assisted by the plate and frame filter, protein can be recovered. The present invention improves the economic benefits, reduces the production costs, and thus solves the problem of difficulty in recovering protein in a production process of an ultrahigh maltose syrup.
