摘要:
将糖蜜稀释5倍后在0.16 MPa的跨膜压力下可获得最佳超滤效果,在1.5 BV/h的流速下可获得最佳离子交换效果。经过清净处理后样品的吸光度和电导率都大幅度降低。再采用强酸型阳离子交换树脂对真空浓缩制得的液体糖中的蔗糖进行酸水解,以蔗糖转化率和还原糖得率为指标,通过单因素及正交实验优化得出最佳酸水解参数为:树脂添加量4 mL,温度80℃,反应时间30 min。最后经过真空浓缩制得的转化糖浆的主要理化指标基本满足了QB/T 4093-2010对转换糖浆的要求,其中还原糖含量达98.9%(占干物质),显示了很好的应用前景。
Abstract:
After diluting molasses by 5 times, the best ultrafiltration effect can be obtained under the transmembrane pressure of 0.16 MPa, and the best ion exchange effect can be obtained at a flow rate of 1.5 BV/h. The absorbance and conductivity of the cleaned sample are greatly reduced. The sucrose in liquid sugar obtained by vacuum concentration was acid-hydrolyzed by strong acid cation exchange resin. The optimal acid hydrolysis parameters were optimized by single factor and orthogonal experiments with sucrose conversion rate and reducing sugar yield. That is, the amount of resin added is 4 mL, the temperature is 80 ° C, and the reaction time is 30 min. Finally, the main physical and chemical indicators of the converted syrup obtained by vacuum concentration basically meet the requirements of QB/T 4093-2010 for converting syrup, wherein the reducing sugar content is 98.9% (accounting for dry matter), showing a good application prospect.
