那麼原糧水分應該怎麼檢測呢？其實檢驗水分測定方法很多，實驗室標準方法有105℃恒重法和130℃高溫定時法
，但操作方法繁瑣且費時，所以麵粉廠常用的方法是紅外線水分快速測定法。其測定步驟是：稱取10gshiyangfangyuchengliangpanshang
，tiaojielingdian，kaihongwaixianzhaoshejiare，zhengfashuifen。dangzhizhenbudong
，jiwuliaohengzhongshi，jixiazhizhenshuduiyingdechuwuliaoshuifenliang。caozuojiandan、數顯直觀
、測定速度快、結果準確重複性較好。
