摘要
通过3条小麦制粉生产线6组淀粉样品的对比分析,探讨了吸风粉淀粉与相应小麦粉淀粉的颗粒特性及糊化特性。结果表明:吸风粉淀粉与小麦粉淀粉的颗粒特性差异较大,吸风粉中小颗粒淀粉居多,大颗粒淀粉较少,损伤淀粉含量较高。吸风粉淀粉的糊化峰值黏度、低谷黏度、最终黏度及衰减值较低;吸风粉淀粉的沉降体积较高,溶解度稍低,凝沉性与冻融稳定性稍差。
Particle characteristics and paste properties of six groups of starch samples, which came from three wheat flour milling production lines respectively, were studied in this paper. The results showed that there was a great difference in particle characteristics between starch made from filter flour and wheat flour. Starch from filter flour had more content of small particles and damaged starch, while fewer content of large particle starch, compared with starch of wheat flour. Starch of filter flour showed lower pastes peak viscosity, valley viscosity, final viscosity and break-down viscosity and higher stability of hot paste. In addition, starch from filter flour showed higher sedimentation volume, lower solubility, retrogradation and freeze -thaw stability.
