评价了三参数GAB方程描述几种吸附数据的能力
农产品GAB方程描述了平衡含水率和平衡含水率之间的关系。
相对湿度（ERH）或水活度（Aw）。以Aw为因变量，方程
变得非常复杂。该模型的残差图表明，它不适合淀粉类产品。对于大多数
产品中，GAB方程的参数与温度不呈现阿伦尼斯型关系。到
将温度项纳入参数中，模型中的参数数量增加，
有用的. GAB方程不是适用于所有农产品的吸附模型。
The three-parameter GAB equation was evaluated for its ability to describe the sorption data for several
agricultural products. The GAB equation describes the relationship between equilibrium moisture content and equilibrium
relative humidity (ERH) or water activity (Aw) at a fixed temperature. With Aw as the dependent variable, the equation
becomes very complex. The residual plots of this model showed that it does not fit well for starchy products. For most
products, the parameters of the GAB equation did not exhibit the Arrhenius-type relationship with temperature. To
incorporate the temperature term into the parameters, the number of parameters in the model increases, making it less
useful. The GAB equation is not an adequate sorption model for all agricultural products.
