用红外水分测定仪快速测定食品中的水分

Rapid Determination of Moisture in Foodstuff with Infrared Moisture Meter

本文采用GB/T5009.3-2003和红外干燥法对三种固体食品样品分别进行了水分检测。结果表明红外干燥法大大缩短了检测时间,且操作简便迅速。经过显著性检验,红外法检测结果与国标中(105±2)℃,(3+1)h的直接干燥法无显著性差异。

This article assayed the moistures of three solid foods with both GB/T5009.3-2003 and infrared method. The results showed that the infrared method takes less time and easier to handle with no significant diversity incomparison with drying oven method at （105 ±2）℃, （3＋1）h.
