测定了海藻糖的水分活度、吸湿等温线和溶解度。通过电湿度计测量的海藻糖饱和溶液的水活度在20和25 ℃下分别为0.98和0.97。还通过十边形水活度仪器测量水活度，发现在20和25摄氏度下分别为0.96和0.95。发现海藻糖在20 ° C下的水分吸附等温线为III型等温线。使用两步法测定10-40 ℃的海藻糖溶解度。在10、20、30和40 ℃下，海藻糖在水中的溶解度分别为42.3、46.6、52.3和59.7%（g海藻糖/100 g（-1）溶液）。(C)1998爱思唯尔科技有限公司版权所有。
The water activity, moisture sorption isotherm, and solubility of trehalose were determined. The water activity of a saturated solution of trehalose, as measured by an electric hygrometer, was 0.98 and 0.97 at 20 and 25 degrees C, respectively. The water activity was also measured by a Decagon water activity instrument and found to be 0.96 and 0.95 at 20 and 25 degrees C, respectively. The moisture sorption isotherm of trehalose at 20 degrees C was found to be a Type III isotherm. Trehalose solubility from 10-40 degrees C was determined using a two step method. The solubility of trehalose in water at 10, 20, 30, and 40 degrees C was found to be 42.3, 46.6, 52.3 and 59.7% (g trehalose 100 g(-1) solution), respectively. (C) 1998 Elsevier Science Ltd.
