“…For the nanocomposite hydrogels, it was observed that the TSI of the 1.5% (w/v) gelatin improved drastically from 70 to 8 as described previously by Sun et al. in a similar study [ 111 ]. In contrast, for the 1.1% (w/v) gelatin, the inclusion of the GO-Ag NPs nanoconjugate tends to favor increased stability during the first two weeks of aging.…”

“…The highest viscosity was found for G-nTA-CNC6, which increased by a factor of 180 and 6 compared to G-nTA and G-OTA-CNC6, respectively. Sun et al observed similar behavior for gelatin-encapsulated tea polyphenol dispersions with CNC, which exhibited a positive effect on viscosity, increasing from 67 to 122 mPa s. For all solutions, the R 2 of shear-thinning curves was higher than 0.90, confirming that the power law model was suitable to describe the rheological behavior of the gelatin-based solutions prepared here. All flow curves are shown in Figure S6 (Supporting Information).…”

This work explored gelatin films incorporated with cellulose nanocrystals (CNC) and tannic acid as bio-based multifunctional food packaging materials. The effects of nonoxidized tannic acid (nTA), oxidized tannic acid (OTA), and CNC on the physical, antioxidant, and antimicrobial properties of gelatin films were investigated. Rheological and ultraviolet (UV)−visible measurements showed that gelatin films with nTA and CNC presented a lower chemical cross-linking and more noncovalent intermolecular interactions in comparison with those containing OTA. When compared to the film containing only nTA, the one with nTA and CNC presented substantial increases in the antioxidant capacity (52%), UV barrier (76%), tensile strength (79%), and water vapor barrier (67%) properties of gelatin. This evidence suggested that noncovalent interactions from nTA molecules and CNC play an important role in the modification of gelatin. The gelatin films designed with nTA and CNC also exhibited antimicrobial effects against Staphylococcus aureus and Escherichia coli. Overall, the incorporation of CNC and nTA as active components to gelatin films is a suitable approach for producing sustainable, multifunctional materials for food packaging and other applications.

“…Therefore, cellulose can potentially be used for the manufacture of biomaterials such as bioplastics, and in several areas and industries (e.g., cosmetic, food, and pharmaceutical industries [ 130 , 131 ] due to its biodegradability, availability, non-toxicity, and biocompatibility [ 132 ].…”

Advantages and Disadvantages of Bioplastics Production from Starch and Lignocellulosic Components

The accumulation of plastic wastes in different environments has become a topic of major concern over the past decades; therefore, technologies and strategies aimed at mitigating the environmental impacts of petroleum products have gained worldwide relevance. In this scenario, the production of bioplastics mainly from polysaccharides such as starch is a growing strategy and a field of intense research. The use of plasticizers, the preparation of blends, and the reinforcement of bioplastics with lignocellulosic components have shown promising and environmentally safe alternatives for overcoming the limitations of bioplastics, mainly due to the availability, biodegradability, and biocompatibility of such resources. This review addresses the production of bioplastics composed of polysaccharides from plant biomass and its advantages and disadvantages.
