摘　　要：本文通过140℃卤素快速干燥法与《食品安全国家标准食品中水分的测定》(GB 5009.3—2016)中第一法直接干燥法,分别检测3个不同水分梯度的小麦、稻谷、玉米的水分值,采用线性拟合分析研究了两种方法测得值之间的相关性,发现两种检测方法测得值显著正相关,相关系数高达0.999 9。从综合对比分析结果来看,卤素快速干燥法具有准确度高、精密度好、适用性强、检测速度快和操作简单的优点。在粮食水分不超过18%时,可代替烘箱干燥法进行水分测定。In this paper,140℃halogen rapid drying method and the first direct drying method in GB 5009.3—2016 were used to detect the water values of wheat,rice and corn with three different water gradients.The correlation between the values measured by the two methods was studied by linear fitting.It was found that the values measured by the two methods were significantly positive correlation,with a correlation coefficient as high as 0.9999.From the comprehensive comparative analysis results,the halogen rapid drying method has the advantages of high accuracy,good precision,strong applicability,fast detection speed and simple operation.When the grain moisture does not exceed 18%,the oven drying method can be replaced for moisture measurement.
