摘要
果葡糖浆是一种由淀粉制备的甜味剂,其在食品工业中的应用十分广泛。在果葡糖浆的工业生产中,对淀粉的水解效率直接影响其效率和品质。研究了玉米淀粉在大生产的液化和糖化过程中,液化液DE值、糖化酶加入量、液化液底物浓度、糖化液pH值、糖化温度等条件对最终糖化液中葡萄糖值的影响。在此基础之上,分析了系统物料平衡,根据实际生产中参数变换可进行及时调整,从而控制系统稳定性,经参数优化、工艺改进及系统稳定控制后,最终糖化葡萄糖值达到96%以上,可获得成品果葡糖浆总糖组分达到96%以上的高品质产品。
Fructose corn syrup is a sweetener prepared mainly from corn starch, it is widely used in the food industry. In the industrial production process of fructose corn syrup, the hydrolysis efficiency of corn starch directly affects the yield and quality of fructose corn syrup. In this paper, the correlation of dextrose with the pH value of liquefied liquid, the amount of glucoamylase enzyme, the concentration of liquefied liquid, the pH of saccharification liquid and the saccharification temperature during the liquefaction of corn starch was systematically studied. Based on the above analysis, the material balance of the whole system was studied, and the optimized parameters can be applied on actual industrial production, the stability of the system can be exactly controlled. Through the process optimization and system stability control, the final saccharified dextrose value can exceed 96%, we can get high quality fructose corn syrup with total sugar content more than 96%.
