摘要
戊聚糖是小麦面粉加工和食品品质重要的影响因子。本研究测定了我国北方冬麦区77个品种（系）籽粒中的戊聚糖含量和蛋白质、湿面筋、沉降值、千粒重等性状。结果表明，不同品种的戊聚糖含量变幅为4.82%～7.28%，戊聚糖含量与籽粒饱满度、湿面筋含量和沉淀值之间存在着极显著的正相关关系，与千粒重具有极显著的负相关关系。同时对“间苯三酚-冰醋酸法”测定小麦戊聚糖的含量进行了讨论。
Wheat pentosan is an important factor affecting the flour processing and food quality. The contents of pentosan,protein,wet gluten,Zeleny volume and 1000 kemel weight of 77 winter wheat varieties planted in north China were investigated.Results showed that the contents of pentosan varied from 4.82% to 7.28%,and grain plumpness,the content of wet gluten and Zeleny volume were significantly positive-related with the content of pentosan,while the 1000 kernel weight was significantly negative related.The method of phloroglucinol to determine the content of wheat pentosan was discussed as well.
