![]() This substance is produced by partial hydrolysis of collagen to form films suitable for food packaging ( Menezes et al., 2019). One of the significant protein-derived films is based on gelatine. These active agents, which are found in the packaging film, can be released onto the food surface and increase the lifespan by decreasing lipid oxidation and microbial growth ( Lee, Yang & Song, 2016).Īmong various kinds of biopolymers, proteins are preferable in developing active packaging due to their greater gas barrier and mechanical properties ( Hanani, Roos & Kerry, 2014). Interestingly, biopolymer films can act as carriers of active ingredients such as antimicrobial and antioxidant agents ( Arfat et al., 2014 Bahram et al., 2014 Lee, Yang & Song, 2016 Hanani, Yee & Khaizura, 2019). Furthermore, biopolymer-based films provide a barrier between the outside and inside packaging to maintain food product quality ( Menezes et al., 2019). In terms of food packaging, natural films are alternative approaches to dealing with serious environmental issues and food safety aspects, representing nontoxic biodegradable films, sustainable materials, and economic resources ( Barbosa-Pereira et al., 2014 Adilah, Jamilah & Hanani, 2018). With the increasing eco-friendly awareness of packaging worldwide, biodegradable plastics are the primary focus as replacements for synthetic polymers ( Chin, Lyn & Hanani, 2017). ![]() Potent antioxidant activity and relatively weak antimicrobial activity of this active gelatine packaging were observed. The thickness, tensile strength, and water content were not significantly affected. The results showed that the mangrove species and extract concentration significantly affected ( p < 0.05) the physical properties of the treated films such as elongation (16.89–19.38%), water vapour transmission (13.31–13.59 g/m 2), and active packaging-antioxidant activities (12.36%–60.98%). The elongation, water vapour transmission, thickness, tensile strength, moisture content, antioxidant and antibacterial properties of the resulting packaging were analysed. Two mangrove species ( Bruguiera gymnorhiza and Sonneratia alba) with four extract concentrations (control, 0.05%, 0.15%, 0.25%, and 0.35%) were used to enrich edible films. This study aimed to create a fish gelatine-based edible film enriched with mangrove extracts and to observe its mechanical and biological properties. Mangroves produce potential bioactive compounds that are suitable as additional agents for active packaging. To increase the functionality of edible films, bioactive compounds can be incorporated into packaging. Fish skin, however, can be subjected to extraction to yield gelatine and used as the primary raw material for edible film production. ![]() Fish skin accounts for one of the significant wastes produced. ![]() The fishery processing industry produces a remarkable number of by-products daily. Physical and functional properties of fish gelatin-based film incorporated with mangrove extracts.
