The influence of storage conditions parameters, including ambient temperature and relative humidity, on the changing pattern with time of brown rice moisture was studied by full factors combination experiments. The static weighing method was designed and the experimental data was analyzed with SAS. The mathematical model was built to describe the relationship between brown rice moisture changing pattern with time and storage conditions, including ambient temperature and relative humidity, significance level of equation less than 0.001 was tested.The results showed that ambient temperature and relative humidity of storage conditions had great influence on the brown rice moisture, the model could illustrate and predict the changing pattern of brown rice moisture under storage conditions, which can guide the safe storage and processing of brown rice.%为探讨贮藏条件对糙米含水率随时间变化规律,以环境温度和相对湿度为影响因素,采用全因素组合试验方法设计试验,应用静力学法进行了试验研究.利用SAS软件处理试验结果,建立了贮藏环境温度和相对湿度对糙米含水率随时间变化影响规律的数学模型,经检验方程显著性水平小于0.001.研究结果表明,贮藏过程中的环境温度和相对湿度对糙米含水率的变化影响显著,所建立的数学模型可以描述和预测糙米含水率在贮藏仓内的变化规律,指导糙米加工及安全贮藏.
