中文摘要：采用静态法测定罗非鱼肉在25、35、45、55℃温度和10%～85%相对湿度范围内的吸湿和解吸平衡含水率,分析温度和相对湿度对罗非鱼平衡含水率的影响。以相关系数和标准误差作为评价指标,对Henderson模型、Chung-Pfost模型、Halsey模型和Oswin修正模型4个数学模型和平衡含水率曲线进行拟合,比较上述平衡含水率模型对实验数据的拟合精度,发现Oswin修正模型较适合于描述罗非鱼的平衡含水率曲线,并分别给出罗非鱼解吸和吸湿平衡含水率的Oswin表达式。

外文摘要：The adsorption and desorption equilibrium moisture contents of tilapia fillets at varying temperatures（25,35,45 ℃ and 55 ℃） and a relative humidity in the range of 10% — 85% were determined by the static method to analyze the effects of temperature and relative humidity on both equilibrium moisture contents.Different equilibrium moisture content curves were fitted according to the four mathematical equations of Henderson,Chung-Pfost,Halsey and Oswin models and evaluated based on correlation coefficient and standard error.From a composition of fitting accuracy,it was found that the modified Oswin model was the most suitable to describe the equilibrium moisture content curves of tilapia.Moreover,Oswin models describing the adsorption and desorption equilibrium moisture contents of tilapia fillets were built.
