“…The apparent viscosity ( η * ) of all solutions decreased with increasing shear rate, as shown in Figure 4A. The solutions showed shear‐thinning behavior that could be treated as a pseudoplastic property of the solution, and a similar phenomenon has been reported in konjac glucomannan‐based film‐forming solutions (Liang, Sun, Cao, Li, & Wang, 2018; Wu et al., 2019). The η * of the solution obviously increased with the addition of Gu and 0.1% nisin, which means that intermolecular interactions formed among the Ge, Gu, and nisin.…”

Demand for antimicrobial packaging films is growing due to public attention to food safety. The structures and properties of gellan gum–guar gum blend films incorporated with nisin were investigated in this paper. Fourier transform infrared spectroscopy, rheological analyses showed intermolecular interactions among gellan gum, guar gum, and nisin. Furthermore, scanning electron microscopy and thermogravimetric analysis also indicated higher compatibility of the blend film components and better thermal stability than the gellan gum film. Tensile strength (TS), elongation at break (EAB) and water vapor permeability (WVP) of the blend films were enhanced with the addition of guar gum. The TS of the blend film reached 2.89 × 103 MPa, the EAB increased to 67.99%, and the WVP increased to 1.80 × 10−5 g/mm·s·Pa. Additionally, the film with nisin had antibacterial activity for Bacillus subtilis. The results demonstrated that a homogenous and smooth antimicrobial film with gellan gum, guar gum, and nisin could be a good option of antimicrobial packaging film for food preservation. Practical Application This work investigated blend package films of gellan gum and guar gum incorporated with nisin. The results showed compatibility and thermal stability of the film were improved with adding a certain amount of guar gum, and also antibacterial activity for Bacillus subtilis of the blend film with nisin. Therefore, it can be used to the development of antimicrobial packaging films.

“…Nanofillers can fill the free space between biopolymer chains, which increases the intermolecular attraction force, making the biopolymer matrix very dense and less permeable [143]. Improvement in TS of polymer films by addition of nanofillers has been observed in films from konjac glucomannan [167], fenugreek seed gum [168], alginate [95], chitosan [169], agar [150], starch [121,143], soy protein [152], whey protein [87], and CMC [170].…”

The Effect of Nanofillers on the Functional Properties of Biopolymer-Based Films: A Review

Waste from non-degradable plastics is becoming an increasingly serious problem. Therefore, more and more research focuses on the development of materials with biodegradable properties. Bio-polymers are excellent raw materials for the production of such materials. Bio-based biopolymer films reinforced with nanostructures have become an interesting area of research. Nanocomposite films are a group of materials that mainly consist of bio-based natural (e.g., chitosan, starch) and synthetic (e.g., poly(lactic acid)) polymers and nanofillers (clay, organic, inorganic, or carbon nanostructures), with different properties. The interaction between environmentally friendly biopolymers and nanofillers leads to the improved functionality of nanocomposite materials. Depending on the properties of nanofillers, new or improved properties of nanocomposites can be obtained such as: barrier properties, improved mechanical strength, antimicrobial, and antioxidant properties or thermal stability. This review compiles information about biopolymers used as the matrix for the films with nanofillers as the active agents. Particular emphasis has been placed on the influence of nanofillers on functional properties of biopolymer films and their possible use within the food industry and food packaging systems. The possible applications of those nanocomposite films within other industries (medicine, drug and chemical industry, tissue engineering) is also briefly summarized.

“…Wang et al showed that addition of polydopamine functionalized microcrystalline cellulose improved significantly mechanical and water vapor barrier properties of konjac glucomannan food packaging films [90]. Moreover, addition of chitosan/gallic acid nanoparticles and chitosan/nisinin to konjac glucomannan films gave one more advantage in terms of antimicrobial activity toward against foodborne pathogens S. aureus, Listeria monocytogens, E. coli and Bacillus cereus [91,92]. Zhang et al investigated konjac glucomannan/carrageenan/nano-silica films for the preservation of the postharvest mushrooms [93].…”

The use of polysaccharide-based materials presents an eco-friendly technological solution, by reducing dependence on fossil resources while reducing a product's carbon footprint, when compared to conventional plastic packaging materials. This review discusses the potential of polysaccharides as a raw material to produce multifunctional materials for food packaging applications. The covered areas include the recent innovations and properties of the polysaccharide-based materials. Emphasis is given to hemicelluloses, marine polysaccharides, and bacterial exopolysaccharides and their potential application in the latest trends of food packaging materials, including edible coatings, intelligent films, and thermo-insulated aerogel packaging.
