The equilibrium moisture contents in broad bean seeds were determined using the gravimetric static method at 5, 20, 40 and 60 degrees C over a range of water activities from 0.110 to 0.877. The sorption capacity of seeds decreased with the increase in temperature at constant water activity. Five models, modified Chung-Pfost, modified Halsey, modified Oswin, modified Henderson, and GAB (Guggenheim-Anderson-de Boer) equations, were applied to analyse the experimental data. The modified Oswin and GAB models were found to be the most suitable for describing the sorption isotherms.
采用重量静态法，在5、20、40和60摄氏度下，于0.110至0.877的一系列水分活度范围内测定蚕豆种子的平衡水分含量。在恒定水分活度下，种子的吸附能力随温度升高而降低。应用修正的Chung-Pfost、修正的Halsey、修正的Oswin、修正的Henderson和GAB（Guggenheim-Anderson-de Boer）方程这五个模型来分析实验数据。发现修正的Oswin模型和GAB模型最适合描述吸附等温线。
