摘要:

为了探讨盐焗鸡微波干燥过程中水分变化规律,通过测定盐焗鸡在不同微波功率条件下的干燥水分比(moisture ratio,MR)和温度变化,并与国内外常用的10 种干燥数学模型进行拟合,结合模型的相关系数(R2)、均方根误差(root mean square error,RMSE)以及卡方(χ2)对模型拟合优劣进行评判,从而确定出最佳的干燥模型。结果表明:Wang and Singh模型能够很好地反映盐焗鸡的微波干燥规律。

Abstract:

This study aimed to explore the moisture changing patterns of salt-baked chicken during microwave drying. The
variations in moisture ratio (MR) and temperature with microwave power.were measured and 10 different mathematical
models were used to describe the changing patterns of MR. The optimum model was chosen based on correlation coefficient
(R2), root mean square error (RMSE) and chi-square (χ2). The results showed that Wang and Singh model was superior to the
others in describing the microwave drying curves of salt-baked chicken.
