| 摘 要： | 对不同产地的＂张杂谷＂品种谷子的直链和支链淀粉含量、胶稠度、碱消值进行了分析,运用双波长法同时测定谷子中直链淀粉和支链淀粉的含量。结果显示,直链淀粉含量、胶稠度和碱消值均因品种和产地不同而有差异。不同产地的4个品种谷子直链淀粉含量平均为14.46%（质量分数,下同）,总淀粉含量平均为71.73%,胶稠度为9.1%～16.3%,碱消值为2.8～3.4。结果初步表明,＂张杂谷＂系列谷子具有较好的食味品质。

| Abstract: | The content of amylose,amylopectin,gel consistency and alkali value of ＂Zhangzagu＂ millet in different areas were analyzed.The dual-wave length spectrophotometry method was used to detect the content of amylose and amylopectin simultaneously in millet.The result shows that the content of amylose,amylopectin,gel consistency and alkali value are different in different varieties and regions.The average contents of amylose and total starch are 14.46% and 71.73% in four varieties of ＂Zhangzagu＂ millet.The gel consistency and alkali value are 9.1%~16.3% and 2.8~3.4,respectively.So ＂Zhangzagu＂ millet may has better eating quality. |
