利用傅里叶变换红外光谱（FTIR）研究了水分环境对30℃贮存过程中无定形壳聚糖醋酸酯膜自发中和和水活度（a(w)）在0.11 ~ 0.84范围内的影响。确定了影响壳聚糖醋酸膜的三个相对湿度范围：i) 0.11
The influence of moisture ambiance on the spontaneous neutralization of amorphous chitosan acetate films during storage at 30 degrees C and water activities (a(w)) in the range of 0.11 to 0.84 is studied by Fourier transform infrared (FTIR) spectroscopy. Three ranges of relative humidity affecting the chitosan acetate films are identified: i) 0.11
