In this study, a high-performance carrageenan/ZnO/chitosan composite film (FCA/ZnO/CS) was fabricated by the solution/dispersion casting method and layer-by-layer method. The first layer was nano-ZnO dispersed in carrageenan solution, and the second layer was chitosan dissolved in acetic acid. The morphology, chemical structure, surface wettability, barrier properties, mechanical properties, optical properties, and antibacterial activity of FCA/ZnO/CS were evaluated compared with a carrageenan film (FCA) and carrageenan/ZnO composite film (FCA/ZnO). This study revealed that the Zn element in FCA/ZnO/CS existed in the form of Zn2+ in FCA/ZnO/CS. There existed electrostatic interaction and hydrogen bonding between CA and CS. As a result, the mechanical strength and transparency of FCA/ZnO/CS were enhanced and the water vapor transmittance of FCA/ZnO/CS was decreased compared with that of FCA/ZnO. Furthermore, the addition of ZnO and CS greatly enhanced the antibacterial activity of Escherichia coli and also had a certain inhibitory effect on Staphylococcus aureus. FCA/ZnO/CS is expected to be a potential candidate material for food packaging, wound dressings, and various surface antimicrobial coatings.

“…Although polyvinyl alcohol (PVA) is a synthetic polymer, PVA:LBG is also a well-studied combination [ 128 ]. Double-layer films made with LBG:PVA and agar:PVA to be used as shrimp freshness indicators were studied by Yao et al [ 129 ]. They integrated red pitaya betacyanins in the LBG layer to provide a “sensitive layer” and TiO 2 in the agar section as the “protective layer”.…”

Locust bean gum (LBG), a vegetable galactomannan extracted from carob tree seeds, is extensively used in the food industry as a thickening agent (E410). Its molecular conformation in aqueous solutions determines its solubility and rheological performance. LBG is an interesting polysaccharide also because of its synergistic behavior with other biopolymers (xanthan gum, carrageenan, etc.). In addition, this hydrocolloid is easily modified by derivatization or crosslinking. These LBG-related products, besides their applications in the food industry, can be used as encapsulation and drug delivery devices, packaging materials, batteries, and catalyst supports, among other biopharmaceutical and industrial uses. As the new derivatized or crosslinked polymers based on LBG are mainly biodegradable and non-toxic, the use of this polysaccharide (by itself or combined with other biopolymers) will contribute to generating greener products, considering the origin of raw materials used, the modification procedures selected and the final destination of the products.

SummaryGrowing awareness of the environmental devastation caused by plastic packaging, particularly in the food industry, has led to the emergence of the concept of a renewable and environmentally safe consumable film as an alternative to plastic. Red pitaya (dragon fruit) peel (RPP), which has a high pectin content, can be used as an additional ingredient or co‐biopolymer to enhance the functional properties of fish gelatin (FG) edible film. Edible films were produced using casting techniques and varying concentrations of FG (3.2%–8.8% w/v) and RPP (0.2%–1.0%) with the aid of Central Composite Design (CCD) of Response Surface Methodology (RSM) by Design Expert 13's software. The optimal formulation consisted of 5.97% (w/v) FG and 0.45% (w/v) RPP. Increasing the concentrations of RPP and FG affected the thickness (0.18–0.36 mm), water solubility (46.72%–66.78%), brightness (60.04–79.02), redness (7.08–28.36), yellowness (2.48–8.44), and opacity (0.85–2.58) of the physical properties. Mechanical testing revealed a tensile strength between 2.76 and 9.34 MPa and a break elongation between 82.78% and 153.89%. The results suggested the physical and mechanical properties of RPP‐based films were greatly affected by concentration of gelatin.
