Sugar cane of raw materials for production of high fructose syrup, sugar by-products can increase the added value. Through the sugar cane production of high fructose syrup key technologies (pretreatment, acid solutions, separation, heterogeneous, refining) study, sugar cane waste for the production of honey industrialized production of high fructose syrup provides a theoretical basis for practical. The main topic of this research and the results are as follows:1. Analysis by the sugar factory, a sulfite sugar cane in the main component analysis, in which sucrose content around 33% to 35%, reducing sugar content of 15% to 16%, ash content of 9% to 12%, Colloidal content 9% to 11%.2. sugar cane pre-treatment of optimum conditions: sugar cane and distilled water for the dilution of 1:0.1, will be diluted by H2SO4 solution transferred to the PH value of about 2.5, add 0.8% flocculation Agent, 100 grams honey processing waste from the precipitation reached 18.87 g, OD reduce the rate of 95.37%.3. Use of acid hydrolysis waste in the sugar cane, fructose in sugar cane to increase the waste content. Waste acid hydrolysis sugar cane is the optimum conditions: the reaction temperature is 80℃, the reaction solution pH value of 2.0, the reaction time is 4.0 h, honey hydrolysis rate of waste can be reached 92.75 %.4. Chemical separation of fructose and glucose is the optimum conditions: fructose and Ca(OH)2 amount of the molar ratio of 1:3, 0-5℃reaction under the conditions of three hours, the reaction of the add 2×10-4% Acrylamide flocculant, making fructose sugar into the results from calcium precipitation, with 30% H3PO4 to wash precipitation, are the high fructose syrup crude products.5. For high-fructose syrup crude product was activated carbon and decoloration strong acid cation resin static desalination refined. Decolorization of activated carbon are: adding activated carbon content 3% (W/V), decolorizing temperature at 50℃, decolorizing time 40 min. Resin the desalination process is: resin amount of 6% (W/V), desalination temperature 40℃, desalination time 2 h. After a series of extraction and refining process, the fructose in the rate of 67.17 %t, fructose loss rate of 8.05 %, after the final decompression concentrated fruit by high-fructose syrup products reached 92.56 %.6. Under the conditions of glucose in alkaline water bath by heating sugar can be transformed into results through the response surface that, through use of alkaline isomerization results will be transformed into glucose sugar is the optimum combination of: temperature 75℃, reaction time 30 min, the solution PH value in 11.50, glucose isomerization rate reached 28.14 %.7. In this paper, Alkaline heterogeneous apparent reaction kinetics study, the establishment of the apparent dynamic model, obtained 75℃, the rate constant k=0.0574min-1, in response to the heterogeneous 75℃at the rate equation:VA =-dcA/dt =0.0574CA;Alkaline isomerization reaction obtained theapparent activation energy 53.74KJ/mol, referring to the former factor k0=2.40286×104s-1 and the reaction rate constant temperature of the relationship:k = 2.40286×10-4e-6461.1/RT...
