摘要(Abstract)：

抗性淀粉作为一种健康成分，对人体健康有着诸多积极影响，包括控制血糖和胰岛素水平、促进肠道健康、控制体重。挤压技术作为一种高温、短时、连续的多功能热机械技术，集混合、搅拌、剪切、加热、熟化和成型于一体，且具有高效环保的特点。水分含量、挤压温度和螺杆转速是影响挤压效果的重要因素。该研究以抗性淀粉(RS)含量为响应值，采用Box-Behnken响应面分析法，通过单因素实验和响应面实验确定了水分含量、挤压温度和螺杆转速的最佳组合。研究结果显示，在山药淀粉和魔芋胶的挤压过程中，水分含量为30%、挤压温度为90℃、螺杆转速为180 r/min时，抗性淀粉含量高达42.58%。该研究为山药淀粉的利用和产品开发提供了重要的理论依据。
