“…The electrospinning parameters such as flow rate, applied voltage, and needle-collector distance were modified along with zein concentrations to obtain bead-free zein fibers. ZF were randomly deposited on traditional food package substrates such as aluminum foil (20 × 20 cm 2 ) or cellulose nanofibril (CNF) film , (diameter: 10 cm). By varying the collection time, the mass of the fibers per surface area can be adjusted.…”

There is an urgent need to develop biodegradable and nontoxic materials from biopolymers and nature-derived antimicrobials to enhance food safety and quality. In this study, electrospinning was used as a one-step, scalable, green synthesis approach to engineer antimicrobial fibers from zein using nontoxic organic solvents and a cocktail of nature-derived antimicrobials which are all FDA-classified Generally Recognized as Safe (GRAS) for food use. Morphological and physicochemical properties of fibers, as well as the dissolution kinetics of antimicrobials were assessed along with their antimicrobial efficacy using state of the art analytical and microbiological methods. A cocktail of nature-derived antimicrobials was developed and included thyme oil, citric acid, and nisin. Its ability to inactivate a broad-spectrum of with food-related pathogens was demonstrated. Morphological characterization of the electrospun antimicrobial fibers revealed bead-free fibers with a small average diameter of 165 nm, whereas physicochemical characterization showed high surface area-to-volume ratio (specific surface area:21.91 m2/g) and presence of antimicrobial analytes in the fibers. The antimicrobials exhibited initial rapid release from the fibers in 2 h into various food simulants. Furthermore, the antimicrobial fibers effectively reduced E. coli and L. innocua populations by ∼5 logs for after 24 h and 1 h of exposure, respectively. More importantly, due to the small diameter and high surface area-to-volume ratio of the fibers, only miniscule quantities of fiber mass and antimicrobials per surface area (2.50 mg/cm2 of fibers) are needed for pathogen inactivation. The scalability of this fiber synthesis process was also demonstrated using a multineedle injector with production yield up to 1 g/h. This study shows the potential of using nature-derived biopolymers and antimicrobials to synthesize fibers for sustainable food packaging materials.

“…The surface charge and chemistry of cellulosic materials are determined by their processing, including pretreatment and mechanical shearing . Residual lignin, hemicellulose, and extractive components from the cellulose source can also have an influence on the surface charge and properties of the material, so there is not one consistent model system. , Additionally, although the fiber charge depends partly on the amount of acid functional groups, it is affected by the pH, ionic strength, and swelling of the fibers. ,, The high aspect ratio and surface area of CNFs allow for greater water retention than other pulps, making them among the highest users of energy for drying and providing a good basis for evaluation of the water retention and phase behavior with PECs. , CNFs have also been previously studied using molecular simulations, − although their interactions with polyelectrolytes and complexation behavior have not been examined, so there is a need to understand the full system, which includes CNF and polyelectrolytes, for further improving the material design principles.…”

Polyelectrolyte Complex Coacervate Assembly with Cellulose Nanofibers

Polyelectrolytes are used in paper manufacturing to increase flocculation and water drainage and improve mechanical properties. In this study, we examine the interaction between charged cellulosic nanomaterials and polyelectrolyte complex coacervates of weak polyelectrolytes, polyacrylic acid salt, and polyallylamine hydrochloride. We observe that by changing the order of addition of the polyelectrolytes to cellulose nanofibers (CNFs), we can tune the interactions between the materials, which in turn changes the degree of association of the coacervates to the CNFs and the rate at which they aggregate. Importantly for the papermaking process, when adding the polyelectrolytes sequentially to the CNFs, we found faster aggregation to the fibers and lower water retention values compared to those when preformed coacervates or CNFs by themselves were used. Coarse-grain molecular dynamic simulations further support the fundamental mechanism of aggregation by taking into consideration the interaction between cellulose and the complexes at the molecular level. The simulations corroborate the experimental observations by showing the importance of strong electrostatic interactions in aggregate formation.

“…It can be calculated by TAPPI T 566 standards and expressed as mN m [ 65 ]. When cellulose nanofibrils are coated on paper board, an increment of 15% in bending stiffness is observed [ 66 ]. Unmodified paper having a bending stiffness of 96.69 3.57 mN m was increased to 122.58 2.91 mN m in the machine direction, and bending stiffness was decreased from 85.51 2.77 to 64.14 3.73 in the cross direction.…”

Research into alternative packaging materials is becoming more and more popular as a result of growing eco-friendly concerns regarding the usage of some petroleum-based polymeric packaging materials and coatings, as well as growing buyer demands for products with nutritious quality and extended shelf lives. Barrier coatings made of naturally renewable biopolymers can be applied to paper packing materials. These biopolymer coatings have the potential to replace the current synthetic paper and paperboard coatings, are strong oxygen and oil barriers, and may prevent the unintended moisture transfer in food goods. An appealing method of controlling the growth and spread of microorganisms in food packaging is the integration of antimicrobial compounds into coatings to create active/functional paper-based packaging materials. Here, in this review of the oxygen/moisture barrier, mechanical, and other characteristics of paper coated with bio-based materials. Examples are used to discuss the current and future uses of bio-based material coatings on paper packaging materials to improve barrier performance.
