| 摘 要： | 为进一步了解糯玉米淀粉的加工特性,推进其工业化应用。采用湿法提取淀粉工艺的淀粉得率为56.7%,蛋白质残留量0.21%。经测定,糯玉米淀粉中支链淀粉含量为97.33%。糯玉米淀粉的物化特性研究显示:糯玉米淀粉的溶解度随着温度的升高而逐渐增大,90℃时淀粉的溶解度达到12%;淀粉糊透明度高、冻融稳定性也较高。

| Abstract: | In order to advance application of waxy corn in the industry,the functionalities of starch from waxy corn are studied in this experiment.Starch is extracted by the technology of wet milling.The yield of starch,the residual quantity of protein and the content of amylopectin are 56.7%,0.21%and 97.33%,respectively.The results of physicochemical properties of starch waxy corn reveal that the solubility of starch can improve with the increasing of temperature,the solubility of starch is 12%at 90℃,the transparency and freeze-thaw stability of starch are higher than before. |
