Study on Properties of Ethylene Glycol Diglycidyl Ether/Montmorillonite Synergistically Enhance Soybean Protein Film

  • In order to improve the water resistance and mechanical properties,expand its application in the field of food industry of SPI materials. In this study,SPI/MMT composite film was prepared with SPI and MMT as the main raw materials and EGED as the crosslinking agent. The results showed that MMT and EGDE could effectively improve the physical and mechanical properties of the composite file. When MMT and EGDE(20%)was added to the SPI composite film,the tensile strength of the composite film was 14.95 MPa. Compared with pure SPI film,the tensile strength of the MMT/SPI composite film increased by 239.77%,the elastic modulus increased by 88.98%,the moisture content decreased by 16.12%,the moisture absorption decreased by 31.07%,the total dissolved matter decreased by 39.68%,and the water vapor transmission decreased by 35.85%.The synergistic enhancement between EGDE and MMT can make the SPI composite film more stable,improve the physical and mechanical properties and water barrier of the composite film.
