中文摘要: 试验研究磷酸化协同超声波处理对玉米淀粉物理性质的影响。比较三聚磷酸钠浓度、超声功率、超声时间、温度4个影响因素对淀粉的交联度、透明度、凝胶强度、糊化特性的影响。试验结果表明:磷酸化协同超声波处理可有效改变玉米淀粉交联度、透明度、凝胶强度和淀粉糊化特性。磷酸化协同超声波可以有效对玉米淀粉进行改性。
Abstract:The effects of phosphorylation combined with ultrasonic treatment on the physical properties of corn starch were studied.Furthermore,the influence of sodium tripolyphosphate concentrations,ultrasonic power,ultrasonic time and temperature in the crosslinking degree,transparency,gel strength,and gelatinization characteristics of starch was assessed.Phosphorylation combined with ultrasonication effectively changed the degree of crosslinking,transparency,gel strength and starch gelatinization properties of corn starch.Therefore,phosphorylation and ultrasound treatment could effectively modify corn starch.
