摘　　要：使用快速黏度分析仪(rapid visco-analyzer,RVA)测定大麦的黏度并通过其特征值可以预测大麦预发芽程度,目前尚无统一的EBC、ASBC标准方法。大麦水分、品种特异性、粉碎粒度等因素在一定程度上影响此方法检测结果。文中建立了一种RVA检测方法,并分析了不同因素对其特征值的影响。实验结果显示,品种初始质量、粉碎粒度对大麦RVA值影响较大,水分影响较小。RVA对大麦预发芽程度的预测相关性显著,可作为一种快速、灵敏、简便的方法,预测大麦预发芽损伤。RVA（Rapid visco-analyzer） can be used to detect the visco of malting barley to predict the sprout damage of malting barley according to the characteristic.However,there are no uniform EBC or ASBC standards of this method up to now.Moisture,varieties specificity,smash size and so on can affect the results of this method.In the study we created a method of RVA,and analyze the effects of these factors to RVA,The results showed that the initial mass and smash size of barley are two significant factor to the RVA value of barley,while the effects of moisture is less important.The level of sprout damage of malting barley had a remarkable correlation with RVA.We can use this fast,sensitive and convenient method to predict the sprout damages of malting barley.
