Structural Characterization and Antioxidant Activity Analysis of Corn Starch/Polyvinyl Alcohol Films loaded with Tea Polyphenols
Corn starch(CS)/polyvinyl alcohol(PVA)electrospinning films loaded with tea polyphenols(TP)were prepared by electrospinning method.The effects of different concentrations of TP on the microstructure and antioxidant activity of the films were studied.The results showed that when the addition of TP was 4%,the film showed good microstructure and compact structure and the clearance rate of ABTS increased to 76%.With the increase of TP addition,the number of bead fibers increased,the intermolecular hydrogen bonding weakened.In conclusion,When the addition of TP is 4%,the electrospinning film has good spinning effect,the strongest intermolecular interaction and strong antioxidant activity.
