为 0.41。相关性分析表明糊化度与压力、保压时间、
温度和加水量皆呈极显著正相关关系（p<0.01），碘
蓝值与压力、保压时间、温度和加水量皆呈正相关
关系，相关性逐渐增加，透明度与压力、保压时间、
温度和加水量皆呈负相关关系，并达到显著水平，
凝胶膨胀率和溶解度与压力、温度、保压时间和加
水量之间都呈弱相关，或正或负，说明各因素协同
影响较大。X 射线衍射分析发现淀粉结晶结构由 A
型向 V 型转化，进一步验证了超高压结合热处理对
大分子结构及大米粉中各成分之间的影响，后续的
分析将进一步探讨淀粉与蛋白质结构变化及相关作
用的变化机制，在实际应用中，也可以调整相关参
数，获得高品质的相关米制品。
