摘要
以高直链玉米淀粉为原料,利用微波辐射加热工艺将淀粉糊化,通过溶液浇铸法制备淀粉基薄膜。探讨了不同增塑剂以及复合增塑剂对高直链淀粉基薄膜性能的影响。结果表明,甘油、山梨醇和木糖等增塑剂对淀粉的塑化作用是比较显著的。与单一的增塑剂相比,复合增塑剂所制备的材料的力学性能更加优良,尤其是甘油与木糖复合增塑所制备的淀粉基薄膜性能更好。
High amylose starch based films were prepared by solution casting under microwave radiation heating technique.Effect of different plasticizers on mechanical properties of the films was studied.The results showed that polyols such as glycerol, sorbitol and xylose could plasticize starch notably. Compared with single plasticizer, multiple plasticizers made the materials more excellent on mechanical properties.Especially the films plasticized by multiple plasticizers composed of glycerol and xylose.
