“…% of PSP, which was related to the PSP dispersion into the FG matrix. Similar results were reported by other authors in gelatin and starch films incorporated with pomegranate peel [28,29], and this behaviour was attributed to the presence of insoluble filler particles embedded in the films. Figure 2 shows the ATR-FTIR spectra obtained for PSP and FG/PSP films.…”

“…% exhibited the best light barrier properties, providing good protection against UV and visible light, which can be an advantage to protect food products susceptible to lipid oxidation [14]. Other authors have also reported this behaviour, in agreement with our results, for different edible films containing pomegranate peel, seed oil or tomato pomace by-products [29,30,45]. A homogeneous granular microstructure was observed for PSP ( Figure 1) by scanning electron microscopy (SEM) with dimensions of PSP particles ranging from 20 to 80 µm in width, with an average value of 40 ± 3 µm.…”

“…Regarding mechanical properties (Table 5), no significant differences (p > 0.05) were observed for elongation at break (EAB) between the control film and FG/PSP10, while a drastic significant (p < 0.05) decrease was observed for the FG/PSP30 film, suggesting a reinforcing effect of PSP due to rigid PSP particles and good compatibility between the filler and the polymer matrix [29], which results in higher rigidity and stiffness at high PSP loading [54]. In addition, low interactions between PSP and the polymer matrix in FG/PSP30 could be responsible of the stress concentration and beginning of fracture resulting in a decrease in the EAB value.…”

“…The extraction of value-added chemicals and compounds from pomegranate peels has been recently reported by some authors [24][25][26][27]. In addition, the use of pomegranate peel, seed oil and seed extract in film formulations has been investigated [28][29][30][31]. However, at the best of our knowledge, no available studies have been reported regarding the direct use of pomegranate seeds and arils by-products into biopolymer matrices.…”

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.

“…They can be obtained from different agricultural resources such as corn hull, wheat hull and straw, doom, hemp, coir, jute, or particles like almond shells, walnut shell (WNS), rice husks, and cassava peel. Shells from different sources (almond coir, hemp doum fiber, and Walnut) have been used in polypropylene‐based composites to enhance thermomechanical, tensile, and flexural properties of composite materials . The mechanical properties of composites reinforced by fillers depend on dispersion, interfacial adhesion, morphology, and particle size and has a noticeable effect on the mechanical properties .…”

Starch-based biodegradable films were prepared by using solution-casting method and reinforced by agricultural residues [apricot and walnut shell (APS and WNS) powder]. The powder of both shells was added in different ratios (0, 2.5, 5, 7.5, and 10%) to investigate the microstructures and performances (mechanical and thermal properties) of the starch-based film. Different techniques such as impact, tensile testing, scanning electron microscope, optical microscope (OM), X-ray diffraction (XRD), water vapor transmission rate (WVTR), and dynamic mechanical analysis were applied to study the thermomechanical and barrier properties of the composite films. Results showed that the incorporation of both shells significantly improved the WVTR and mechanical properties of starch-based films. The shells powder was significantly increased the Young's modulus and tensile strength of the starch-based films. Both OM and SEM results showed reasonably good compatibility between starch and reinforced shells. OM and XRD indicated that the APS and WNS not only retained their crystalline structure in the film but they also strengthened the peak intensity of the film. This phenomenon can be used to explain the mechanism of mechanical reinforcement. Since all the components used in the preparation of the films are food grade ingredients, it is expected that the films developed in this work will be used for food packaging applications.

Starch, among the other biopolymers, is a very appealing biopolymer, due to its abundant supply, intrinsic biodegradability, and yearly renewability. Because they are inexpensive substances and are flexible to be handled using ordinary machines of plastic processing, starches make an appealing low cost basis for novel biodegradable polymers. Meanwhile, the well‐known concerns of fossil fuel scarcity and the rising demand of reducing the pressure on the environment caused by the widespread usage of petrochemically produced polymers, the production, and uses of starch‐based materials that are biodegradable have attracted a lot of attention. This article begins with a discussion of starch structures in general, including both physical and chemical features. Then, starch‐based material thermal processing is explained, which covers both basic sciences such as phase transition, rheology, and microstructure and processing methodologies, formulations, and circumstances. The multiphase transitions and distinct microstructure during heat processing make starch an excellent prototype system for illustrating and conceptualizing structure–processing–property connections in polymers. For processing starch‐based materials, several traditional methods, for example, injection compression molding, casting, and extrusion and few novel processes such as reactive extrusion have also been applied. Finally, the current advancements in starch‐based materials have been explained.
