Processing has a great influence on starch digestibility and increasing attention has been paid to the application of emerging environmentally friendly starch modification technology. Hierarchical structure and digestibility of sugar palm (Arenga pinnata) starch (APS) following high speed jet (HSJ) treatment are investigated. HSJ treatment (at 200 MPa for different processing cycles) significantly increases the rapidly digestible starch (RDS) content and decreases the slowly digestible starch and resistant starch content and significantly decreases the molecular weight of amylopectin and destroys granular structures with increasing treatment passes. The number of double helices is also reduced. The structural changes alter the digestibility of uncooked APS and transform the slowly digestible and/or resistant starch to the rapidly digestible form.

高速喷射处理对糖棕榈淀粉（Arenga pinnata）淀粉的多尺度结构和消化率的深入了解

加工对淀粉的消化率有很大的影响，并且人们越来越关注新兴的环保淀粉改性技术的应用。palm榔（Arenga pinnata）的层次结构和消化率。）研究了高速喷射（HSJ）处理后的淀粉（APS）。HSJ处理（在不同处理周期的200 MPa下进行处理）显着增加了快速消化淀粉（RDS）的含量，并降低了缓慢消化淀粉和抗性淀粉的含量，并随着处理次数的增加显着降低了支链淀粉的分子量并破坏了颗粒结构。双螺旋的数量也减少了。结构变化会改变未煮过的APS的消化率，并将缓慢消化和/或抗性淀粉转化为快速消化形式。
