“…Different strategies have been applied in the literature to control the release rate of lysozyme. Most of these strategies focused on changing packaging material morphology by polymer concentration (Gemili, Yemenicioglu, & Altinkaya, 2009), plasticizer concentration (Min, Rumsey, & Krochta, 2008), additive concentration and type (Mastromatteo, Lecce, De Vietro, Favia, & Del Nobile, 2011), degree of crosslinking (Buonocore et al, 2003a;Buonocore, Del Nobile, Panizza, Corbo, & Nicolais, 2003b;Buonocore et al, 2004;Fajardo, Balaguer, Gomez-Estaca, Gavara, & HernandezMunoz, 2014;Ma, Tang, Yin, Yang, & Qi, 2013;Ozdemir & Floros, 2001) and number of layers (Buonocore et al, 2004;Conte, Buonocore, Nicolais, & Del Nobile, 2003). In another approach, the pH of the release medium was changed to control release of lysozyme from the films (Benelhadj et al, 2016;Mendes de Souza, Fern andez, L opez-Carballo, Gavara, & Hern andez-Muñoz, 2010).…”
