Abstract

The invention relates to a method for preparing high fructose corn syrup by using glucose syrup. The method includes: subjecting the glucose syrup to saccharification, discoloration, ion exchanging, concentration, blending, isomerization and ion exchanging. The glucose syrup may be processed and converted into the high fructose corn syrup greater than 43% in fructose content, the high fructose corn syrup is directly applicable to the production of fructose by chromatographic separation, the glucose syrup is fully utilized, product cost is substantially decreased, and product market competitiveness is improved.

Description

technical field [0001] The invention relates to a method for preparing fructose syrup from glucose syrup, which belongs to the technical field of fructose syrup preparation. Background technique [0002] At present, the production of fructose is mainly based on fructose syrup (in the dry component of fructose syrup: 43% fructose, 52% glucose, 5% oligosaccharides) as raw material, and the fructose syrup is separated into two parts by simulated moving bed chromatography. One part is the crude fructose solution, and the other part is the glucose solution; wherein the crude fructose solution is subjected to nanofiltration to remove oligosaccharides, and then concentrated to crystallize fructose. The glucose solution, together with oligosaccharides, is a by-product of fructose production (collectively referred to as glucose syrup). It can be seen that in the actual production of fructose, only 43% of fructose in fructose syrup is effectively utilized, and the remaining glucose s...
