| 摘 要： | 文章探讨了烤石莼（Ulvapertusa）等温吸湿曲线的特性。试验中对烤石莼在5—40℃范围的等温吸湿变化规律进行了研究，将曲线通过计算机拟合获得相应的回归方程。通过回归拟合建立烤石莼在5～40℃条件下的干基含水量与水分活度对应关系的数学模型。研究结果表明，烤石莼等温吸湿曲线在5～40℃均呈现经典的反S型。用计算机拟合获得的曲线回归方程相关系数大，计算误差小。

| Abstract: | The characteristic of the isothermal moisture sorption of grilled Ulva pertusa was studied. In the experiment, moisture absorption curve from 5℃ to 40% were drawn, and then corresponding regression equation of each curve was obtained by curve fitting. Mathematical model of corresponding relation between dry-basis moisture content and water activity of grilled U. pertusa under the condition of 5℃ to 40℃ was established according to the curve regression equation. The results showed that the moisture sorption isotherm of grilled U. pertusa was inverse-S shape from 5℃ to 40℃. The curve regression equation obtained by computer has big correlation coefficient and small calculation error. |
