| 中文摘要: |
| 为探究五种江苏杂豆淀粉的理化特性差异，以苏豌9、苏绿7、苏蚕4、苏豇12和苏红1共5种杂豆为原材料，采用碱法提取淀粉，对其颗粒结构和理化特性进行分析比较。结果表明，五种杂豆淀粉颗粒大多呈不规则椭圆形，表面光滑并伴有沟横，体积平均径在16.68μm~38.97μm之间。淀粉颗粒均呈典型的C型结构，相对结晶度差异较大（15.92%~23.44%）。苏豌9、苏蚕4和苏红1具有较好的流变性质和吸水性，苏绿7和苏豇12较难糊化，凝沉速率慢，凝沉体积大。 |
| 英文摘要: |
| To explore the differences in physicochemical properties of five types of Jiangsu miscellaneous bean starch, five types of miscellaneous beans including Su Wan 9, Su Lv 7, Su Can 4, Su Jiang 12, and Su Hong 1 were used as raw materials, Starch was extracted using alkaline method, and their particle structure and physicochemical properties were analyzed and compared. The results showed that most of the five types of miscellaneous bean starch granules were irregular ellipses with smooth surfaces and grooves, with an average volume diameter ranging from 16.68 μm to 38.97 μm. Starch granules all had a typical C-type structure, with significant differences in relative crystallinity (15.92%~23.44%). Su Wan 9, Su Can 4, and Su Hong 1 had good rheological properties and water absorption, while Su Lv 7 and Su Jiang 12 were difficult to gelatinize, with slow coagulation rate and large coagulation volume. |
