试验研究了新鲜、预处理 (漂白并浸入40 0 白利糖度、4℃溶液中 6 h和冷冻干燥的三种芭蕉的吸附特性。采用静态重量分析法(使用 H2 SO4溶液 ) ,测定了 40、50和 6 0℃下 ,aw 范围为 0 .2～ 0 .7的吸湿等温线。按BET等温线模型中规定的分类系统 ,新鲜芭蕉的等温线属 BET 型 ,而
The adsorption characteristics of fresh, pretreatment (bleaching and immersion in 40 Brix, freeze-dried at 4 ℃ for 6 h and freeze-drying) were studied.The results of static gravimetric analysis (using H2 SO4 solution) 50 and 6 0 ℃, aw range of 0 .2 ~ 0 7 hygroscopic isotherms. According to the BET isotherm model of the classification system, the fresh banana isotherm is a BET type, and
