Water sorption by isolated tomato fruit cuticular membranes was measured over the whole range of relative humidities. Using the water sorption isotherm, the strength of water binding and the number of binding sites were estimated. Water clustering was predicted from the isotherm analysis and data obtained by differential scanning calorimetry suggested that the water does not plasticize the tomato fruit cuticle. Water sorption characteristics reflect the hydrophobic character of this biopolymer.
在整个相对湿度范围内测量了分离的番茄果实角质膜的水分吸附情况。利用水分吸附等温线，估算了水结合强度和结合位点数量。通过等温线分析预测了水的聚集，差示扫描量热法获得的数据表明水不会使番茄果实表皮发生增塑。水分吸附特性反映了这种生物聚合物的疏水特性。
