| Abstract: | Objective] To explore a method for correctly and rapidly determining moisture content in rice. Method ] Karl Fischer method was adopted to determine moisture content in rice, the results were compared with that by direct drying method. Result] The results from di- rect drying method and Karl Fischer method are similar, and Karl Fischer method can determine the rice moisture more accurately, and is suit- able for rapid quantitative analysis for moisture content in rice. Conclusion] The study can provide reference basis for daily detection of mois- ture in rice. |
