Abstract The development of the bioplastics industry addresses critical issues such as environmental pollution and food safety concerns. However, the industrialization of bioplastics remains underdeveloped due to challenges such as high production costs and suboptimal material characteristics. To enhance these characteristics, this study investigates bioplastics reinforced with Nanocrystalline Cellulose (NCC) derived from Oil Palm Empty Fruit Bunches (OPEFB), incorporating dispersing agents. The research employs a Central Composite Design from the Response Surface Methodology (RSM) with two factors: the type of dispersing agent (KCl and NaCl) and the NCC concentration from OPEFB (1%–5%), along with the dispersing… More >

Abstract The food industry prioritizes food safety throughout the entire production process. This involves closely monitoring and evaluating all potential sources of biological or chemical contamination, starting from entering raw materials into the production chain and continuing to the final product. Biofilms on food surfaces or containers can harbor dangerous pathogens, such as Listeria monocytogenes. Therefore, it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections. Recently, there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry, especially since traditional disinfectants or antibiotics… More >

Abstract Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract

Abstract Petrochemical plastics are widely used for food protection and preservation; however, they exhibit poor biodegradability, resisting natural degradation through physical, chemical, or enzymatic processes. As a sustainable alternative to conventional plastic packaging, edible films offer effective barriers against moisture, gases, and microbial contamination while being biodegradable, biocompatible, and environmentally friendly. In this study, novel active food packaging materials (in film form) were developed by incorporating starch, carrageenan, nanocellulose (NC), Aloe vera, and hibiscus flower extract. The effects of varying the matrix composition (26.5–73.5 wt.% starch/carrageenan), NC concentration (2.77–17.07 wt.%), and particle type (fibers or crystals) on… More > Graphic Abstract

Abstract The continuous increase in petroleum-based plastic food packaging has led to numerous environmental concerns. One effort to reduce the use of plastic packaging in food is through preservation using biopolymer-based packaging. Among the many types of biopolymers, chitosan is widely used and researched due to its non-toxic, antimicrobial, and antifungal properties. Chitosan is widely available since it is a compound extracted from seafood waste, especially shrimps and crabs. The biodegradability and biocompatibility of chitosan also showed good potential for various applications. These characteristics and properties make chitosan an attractive biopolymer to be implemented as food… More > Graphic Abstract

Abstract This study aimed to develop and characterize biodegradable packaging film from blends of two natural polysaccharides, i.e., agar and glucomannan. The glucomannan used was derived from the specific tuber plant Amorphophallus oncophyllus (locally known as “porang”), which grows abundantly in Indonesian forests and remains underutilized. Various ratios of agar and porang-glucomannan (PG) proportions were formulated to produce a food packaging film, which was subsequently tested for its mechanical, physical, chemical, and thermal properties. The results showed that the inclusion of PG to the film formulations notably enhanced the stretchability of agar films, achieving maximum a… More > Graphic Abstract

Abstract The extensive use of polymeric materials in single-use packaging has driven the need to develop biodegradable alternatives. This study investigates the incorporation of graphene oxide (GO) and Moringa oleifera seed oil (MOSO) into a gelatin matrix to create polymer films and evaluate their potential as active packaging materials. The properties of these films were evaluated using structural, thermal, mechanical, optical, and physicochemical methods to determine their suitability for food packaging applications. The results showed that GO and MOSO were homogeneously dispersed in the gelatin matrix, forming colloidal particles (around 5 µm in diameter). The addition… More > Graphic Abstract

Abstract Fuller earth (FE) nanoclay is a naturally occurring mineral with a high surface area, is highly abundant, and has a low purchasing cost, making it an excellent candidate for nanocomposite production. The study highlights the novelty of using FE nanoclay in combination with polyvinyl alcohol (PVA) to create a bio-nanocomposite that meets the need for sustainable packaging solutions, underscoring its potential to reduce environmental impact while maintaining product quality in food packaging applications. The solvent casting process, a reliable way to evenly disperse nanofillers in polymer matrices, has been employed in this work to incorporate… More >

Abstract The synergistic effect of organoclay (OC) and zinc oxide (ZnO) nanoparticles on the crucial properties of poly(lactic acid) (PLA) nanocomposite films was systematically investigated herein. After their incorporation into PLA via the solvent casting technique, the water vapor barrier property of the PLA/OC/ZnO film improved by a maximum of 86% compared to the neat PLA film without the deterioration of Young’s modulus or the tensile strength. Moreover, the film’s self-antibacterial activity against foodborne pathogens, including gram-negative (Escherichia coli, E. coli) and gram-positive (Staphylococcus aureus, S. aureus) bacteria, was enhanced by a maximum of approximately 98–99% compared to the neat… More > Graphic Abstract
