摘　　要：小麦硬度的测定方法较多,常用的有角质率法、颗粒度指数法、单颗粒硬度指数法、硬度指数法等。硬度的主要影响因素有品种、水分和温度,硬度与磨粉加工中的物料质量密切相关,与制品质量紧密相联。The rongalite lump in wheat flour is regarded as detected object.The national standard method of testing rongalite lump adopts liquid chromatography detection.But it is difficult for ordinary laboratory to own liquid chromatography because of the expensive price.This limitation hinders various regions from implementing inspection work.The qualitative test method of rongalite lump in wheat flour is characterized by simple experiments,time-saving,high sensitivity.The minimum detection limit is 5 mg/kg.
