Abstract:
蔗糖酯是一种对环境无害的表面活性剂,含有与淀粉相容的极性头.将不同比例蔗糖硬脂酸酯加入到玉米淀粉或20%尿素增塑的玉米淀粉中,在热水中煮浆后浇铸成膜.采用X-射线衍射法表征淀粉膜的结晶结构,并测定了浆膜在不同相对湿度下的吸湿性以及浆膜的拉伸性能.结果表明,蔗糖酯可与淀粉形成V-型包合配合物,并影响淀粉的B-型结晶,因此改变淀粉的吸湿性和力学性能.添加0.5%蔗糖酯使淀粉的吸湿率提高,随着蔗糖酯进一步增加,淀粉的吸湿率下降.含尿素20%的淀粉混合物中添加不同比例的蔗糖酯,对淀粉材料的结晶度、结晶形态,以及吸湿率和力学性能产生了不同的影响.蔗糖酯与尿素对淀粉材料改性具有协效作用.含蔗糖酯0.5%的尿素增塑淀粉膜显示出非晶特征,且具有较高的断裂伸长.
