“…The influence of CNFs on the films' mechanical characteristics is presented in Figure 1. Sani et al, 2018;Wang, Liu, et al, 2017). A similar mechanism was reported for sodium caseinate in a previous study (Ranjbaryan et al, 2019).…”

“…The rise in EAB may be attributed to the reinforcement of the soft gelatin biopolymer with rigid nanofillers, resulting in increased hardness. However, it had a brittleness effect on bionanocomposite film compared with pure biopolymer (Alizadeh‐Sani et al., 2018; Wang, Liu, et al, 2017). A similar mechanism was reported for sodium caseinate in a previous study (Ranjbaryan et al., 2019).…”

“…In Figure 3, the SEM images of the surface morphology of the gelatin, G/CNF, and G/CNF/ZnO films are shown. The pure gelatin sample featured a surface that was smooth, compact, and homogeneous without porosity, proving an ordered film structure (Wang, Liu, et al, 2017). As seen, the G/CNF films had homogeneous surfaces with little roughness, lacking air bubbles and cracks; this indicates appropriate compound mixing.…”

In general, food packaging is aimed at preventing food degradation caused by physical and chemical processes or microbial contamination, thereby reducing aroma loss and maintaining product quality during its extended shelf life. To achieve this, the movement of water and gases must be restricted by the packaging material, which must simultaneously conform to the physicomechanical requirements (Talegaonkar, Sharma, Pandey, Mishra, & Wimmer, 2017). The petrochemical polymers currently utilized as food packaging are nonrenewable and nonbiodegradable, presenting remarkable threats such as natural resource depletion, energy crises, global warming, and ecological problems pertaining to waste generation and disposal (Sarwar, Niazi, Jahan, Ahmad, & Hussain, 2018). In recent decades, environmental concerns and increasing consumer demand for healthy and nutritious

“…FG is highly hygroscopic, showing poor water resistance and low mechanical strength [10]. Indeed, cellulose nanofibers [11], nano-SiO 2 particles [12], montmorillonite [13], coconut husk [14], or chitosan nanoparticles [15] have been proposed as reinforcing agents in FG matrices. Another interesting approach was recently proposed by using Maillard reactions induced by heating FG films with glucose resulting in the increase in tensile strength, elongation at break and glass transition temperatures [16].…”

Gelatin-Based Antimicrobial Films Incorporating Pomegranate (Punica granatum L.) Seed Juice by-Product

et al. 2019

Pomegranate (Punica granatum L.) seed juice by-product (PSP) was added as reinforcing and antimicrobial agent to fish gelatin (FG) films as a promising eco-friendly active material for food packaging applications. A complete linkage analysis of polysaccharides in PSP showed xylan and cellulose as main components. This residue showed also high total phenolic content and antioxidant activity. Three formulations were processed by adding PSP to FG (0, 10, 30 wt. %) by the casting technique, showing films with 10 wt. % of PSP the best performance. The addition of PSP decreased elongation at break and increased stiffness in the FG films, particularly for 30 wt. % loading. A good compatibility between FG and PSP was observed by SEM. No significant (p < 0.05) differences were obtained for barrier properties to oxygen and water vapour permeability compared to the control with the incorporation of PSP, whereas water resistance considerably increased and transparency values decreased (p < 0.05). High thermal stability of films and inhibition against S. aureus were observed. The addition of PSP at 10 wt. % into FG was shown as a potential strategy to maintain the integrity of the material and protect food against lipid oxidation, reducing huge amounts of pomegranate and fish wastes.

“…Fish gelatin (FG), a type of gelatin that can provide materials with ultraviolet and oxygen barrier properties, can be extracted from fish bones and skin, and has been used an alternative raw material for a wide range of applications [9,10,11]. However, FG’s inflexible and hydrophilic character, and consequently its poor mechanical properties in the presence of humid environments, limit its application [10,12,13]. As a consequence, the flexible properties and water-resistance of FG-based films should be improved further to meet the demand of practical applications.…”

Synergistic Effect of Halloysite Nanotubes and Glycerol on the Physical Properties of Fish Gelatin Films

et al. 2018

View full text Add to dashboard Cite

Fish gelatin (FG)/glycerol (GE)/halloysite (HT) composite films were prepared by casting method. The morphology of the composite films was observed by scanning electron microscopy (SEM). The effects of HT and GE addition on the mechanical properties, water resistance and optical properties of the composites were investigated. Results showed that with increasing GE content, the elongation at composite breaks increased significantly, but their tensile strength (TS) and water resistance decreased. SEM results showed that GE can partly promote HT dispersion in composites. TS and water resistance also increased with the addition of HTs. Well-dispersed HTs in the FG matrix decreased the moisture uptake and water solubility of the composites. All films showed a transparency higher than 80% across the visible light region (400–800 nm), thereby indicating that light transmittance of the resulting nanocomposites was slightly affected by GE and HTs.
