Application Note: Moisture Determination of Rice

It is important to measure rice moisture content throughout the production process. At each step, there is an optimal moisture content that impact the quality of rice, its longevity, the overall cost of production and therefore end price and profit.

rice moisture content is important to keep rice from spoiling

Our application scientists determined the rice moisture content using Precisa’s XM60 Halogen Moisture Analyzer. 2 grams of ground white rice was placed across the pan. Using a Standard temperature program at 105 oC, 6 measurements were taken, with the average time of analysis taking 6.5 mins. The average moisture content of rice was found to be 11.79%. This aligned well with the reference sample which used an air oven to dry the sample at a temperature of 105 oC for hours and found the moisture content to be 11.88%.
