- 使用快速粘度分析 (RVA) 和动态风湿学进行分析.
- 通过富里埃变换红外光谱 (FTIR) 和X射线衍射 (XRD) 进行表征.
- 在体外消化试验测试以确定快消化粉 (RDS) 和耐性粉 (RS) 含量.
主要成果:
- 酸降低了土豆粉凝的粘度,削弱了土豆粉凝的粘度弹性 (G',G′′).
- 酸和粉之间的非共价相互作用降低了短距离秩序和热稳定性.
- 微观结构分析显示了更多孔的粉-酸复合物.
- 所有测试的酸都降低了RDS和增加了RS含量,酸显示出最强的效果.
结论:
- 酸显著改变了土豆粉的物理化学和结构性质.
- 这些相互作用调节了粉在体外的消化能力,增加了耐性粉的形成.
- 酸,特别是酸,对开发消化缓慢的粉食品有希望.
