摘　　要：该文采用布拉班德黏度仪、差示扫描量热仪、体外酶解和分光光度法等方法研究了添加水溶性大豆多糖对马铃薯淀粉黏度特性、糊化特性、消化特性及透明度、溶解度和膨胀力的影响。结果表明,水溶性大豆多糖添加量对马铃薯淀粉的糊化温度基本无影响;随着水溶性大豆多糖添加量的增加,马铃薯淀粉焓变缓慢增加,而透明度、溶解度和膨胀力下降;水溶性大豆多糖能降低马铃薯淀粉峰值黏度、崩解值和回生值,抑制马铃薯淀粉的水解与老化,增强马铃薯淀粉的抗消化性能。该研究可为水溶性大豆多糖在淀粉基食品中的应用提供指导。This paper aimed to explore the effects of soluble soybean polysaccharides on the physicochemical properties of potato starch. The effect of adding soluble soybean polysaccharides on the viscosity properties,gelatinization properties,digestion properties as well as transparency,solubility and swelling were determined using Brabender viscometer,differential scanning calorimetry,enzymatic hydrolysis in vitro and spectrophotometry method,respectively. The results showed that adding soluble soybean polysaccharides had no effect on the gelatinization temperature of potato starch. As the amount of soluble soybean polysaccharides increased,the enthalpy of potato starch increased slowly,however,its transparency,solubility and swelling power decreased. Adding soluble soybean polysaccharides could reduce the peak viscosity,breakdown and setback of potato starch,inhibit its hydrolysis and retrogradation,and enhance its antidigestibility. In conclusion,this study provides guidances for the application of soybean soluble polysaccharides in starch-based foods.
