摘  要:
采用单因素和响应面分析法优化普鲁兰多糖-明胶复合膜配方。结果表明:甘油添加量对抗拉强度的影响最大,普鲁兰多糖添加量的影响最小。当普鲁兰多糖添加量2.00%、明胶添加量5.00%、甘油添加量1.00%时,其抗拉强度达到最大,为85.18MPa,验证实验结果为89.83MPa,二者的相对误差为5.18%,响应面法优化的组成真实可靠。

摘  要:
The aim of the present study was to optimize the formulation of pullulan-gelatin composite films using one-factor-at-time design and response surface methodology.The tensile strength of pullulan-gelatin composite films was affected most by glycerol concentration and least by pullulan concentration.Pullulan-gelatin composite films composed of 2% pullulan,5% gelatin and 1% glycerol showed the highest tensile strength.A relative error of 5.18% was found between the actual(89.83 MPa) and predicted(85.18 MPa) tensile strength,suggesting high reliability of the optimized formulation.
