Study On Application Of CSEP Technique In Extraction Of Fructose

Fructose is the sweetest natural sugar, it has the high nutritional value , the low thermal characteristic, widely applies to food, drink, feed, medicine and so on. The fructose and the glucose are isomeric compounds, they are difficult to separate from each other, and therefore, the industrial production of fructose mainly is the fructose corn syrupsn. This paper introduces taking the fructose corn syrupsn as the raw material, the pure water for elutes, using continuous chromatographic separator (CSEP) to separate the fructose from the fructose corn syrupsn .Through to analysis of the degree of dissociation influence factors, has determined the resin model, the resin natural target, as well as feeding volume, feeding density, feeding speed of flow and operating temperature. Enlarges using the single column empirical datum to the continuous chromatographic separator, has determined the method of piping arrangement. Passes through to the result, introduces the system optimization method. Then feeding fructose corn syrupsn, whose content is 42g/100ml, in CSEP to separate, after that, carrys on the concentration crystallization, the result indicates that, the quality of crystallization fructose completely conform to the USP standard. The purity of fructose is 98.93%, the density is 39.13%, the purity of glucose is 98.23%, the yield reachs 97.97%. Using this craft each ton resin produces fructose 0.02 ton an hour, extracting 1 ton fructose needs water 3.13 tons.Through to insert the CSEP to produce fructose, invests less, the production working procedure reduces, the flow is shorter, the operating costs low, operation is easy, the product enrichs, the labor intensity is low, automaticity is higher,it strengthens the competitive advantage of corn deep processing profession.
