| 摘 要： | 研究添加蜂蜡(质量分数分别为1%、2%、3%、4%、6%、8%和10%)和甘油(质量分数分别为40%和50%)交互作用对大豆蛋白膜机械性能和阻隔性能的影响。结果表明,蜂蜡以固体小颗粒的状态分散于大豆蛋白膜中,能够提高大豆蛋白膜的抗张强度、氧气透过率、阻水性能和表面接触角,降低水蒸气透过率以及断裂延伸率。甘油浓度升高有助于蜂蜡与大豆蛋白分子相结合,提高大豆蛋白膜的综合性能。 |

| Abstract: | The effect of beeswax and glycerol incorporation on mechanical and barrier properties of soy protein isolate films was evaluated.Soy protein isolate films,containing beeswax of 1%,2%,3%,4%,6%,8% or 10%(beeswax/protein),and glycerol of 40% or 50%(glycerol/protein) respectively,were prepared.The beeswax addition,which presented as dispersing granule in soy protein isolate film matrix,increased the tensile strength,oxygen permeability and contact angle of the soy protein isolate films,while the water vapor per... |
