| 摘 要： | 本文以干燥特性、色泽、复水性以及抗坏血酸保留率为评价指标,研究了不同干燥温度(60、70、80、90℃)下中短波红外辐射和热风干燥对番木瓜片品质的影响。结果表明:与热风干燥相比,相同温度条件下中短波红外干燥速率更快,所需干燥时间更短;随着干燥温度的升高,两种干燥方式下的水分有效扩散系数均呈升高趋势,番木瓜片中短波红外干燥和热风干燥水分有效扩散系数分别为0.58546×10-10~9.87313×10-10 m2/s、0.01179×10-10~4.88646×10-10 m2/s;番木瓜片中短波红外干燥的活化能32.13 k J/mol低于热风干燥的活化能33.28 k J/mol;此外,中短波红外干燥后番木瓜片的色泽和产品的复水性更好,而番木瓜片的中短波红外干燥抗坏血酸保留率低于热风干燥。综合考虑,试验范围内中短波红外干燥温度为70℃条件下所得产品的品质最好。
