Preparation and characterization of cross-linking composite films based on sodium alginate and pomelo pectin
摘要
Abstract
The optimization of the composite films formula which using sodium alginate and pomelo pectin as basic materials,glycerol and different kinds of lipids was studied.The property such as tensile strength,fracture strain,and water vapor were studied.The optimal formula was:SA-PEC mass ratio 10/2,glycerol 0.3%,and paraffin wax 0.12%.The composite membrane was cross-linked with CaCl2、BaCl2、FeCl3 and Al2(SO4)3.When CaCl23%,crosslinking time 3min,the performance of SA-PEC composite film increased.Composite film was characterized by FTIR,SEM,XRD and the contact angle.The experiment results showed that SA-PEC composite film had good compatibility between different components,and crosslinking with CaCl2 could improve the barrier property,mechanical property and water resistance of the membrane significantly.SA-PEC modified composite membrane is a degradable composite packaging film and has a with a great potential.关键词
