“…Plasticizers are usually added to modify the mechanical properties of films, and glycerol and PEG are the most widely used plasticizers (Ghanbarzadeh et al, 2007;Huo et al, 2018;Sothornvit & Krochta, 2005;Vieira, Silva, Santos, & Beppu, 2011). Compositing and cross-linking have been made to improve the tensile strength, elongation at break, and other properties of zein films (Cho, Lee, & Rhee, 2010;Deng, Li, Feng, & Zhang, 2019;Ghanbarzadeh & Oromiehi, 2008;Giteru, Ali, & Oey, 2019;Khalil, Deraz, Elrahman, & El-Fawal, 2015;Li et al, 2018;Mushtaq, Gani, Gani, Punoo, & Masoodi, 2018;Turasan, Barber, Malm, & Kokini, 2018;Wihodo & Moraru, 2013).…”
