“…FTIR study showed proper compatibility and synergy between the MF and BN particles with the gelatine matrix. This study further confirms the possibilities of nanoclay protein-based polymers for food packaging [ 37 ]. Also, as in the studies of Shams et al (2019), whey protein isolate–gelatine nanocomposites–natural orange peel extract and Cloisite 30B film improved the water barrier properties and mechanical properties with the inclusion of nanoclay [ 38 ].…”

“…Nanocomposites are considered a favourable alternative to plastic, as they have an ability for nanoscale dispersion; this brings significant improvement in the mechanical and physical properties [ 37 ]. In this study, gelatine, nanofilms containing Agave angustifolia Haw microfibres (MF) were produced using a thermo compression technique.…”

Food packaging is an important concept for consumer satisfaction and the increased shelf life of food products. The introduction of novel food packaging materials has become an emerging trend in recent years, which could be mainly due to environmental pollution caused by plastic packaging and to reduce food waste. Recently, numerous studies have been carried out on nanoclays or nanolayered silicate to be used in packaging material development as reinforcing filler composites. Different types of nanoclays have been used as food packaging materials, while montmorillonite (MMT), halloysite, bentonite (BT), Cloisite, and organically modified nanoclays have become of great interest. The incorporation of nanoclays into the packaging matrix improves the mechanical and barrier properties and at the same time prolongs the biodegradation of the packaging material. The purpose of this article is to examine the development of nanoclay-based food packaging materials. The review article highlights the current state of research on bio-based polymers with nanoclay for food packaging. In addition, the report analyses the mechanical, barrier, and antibacterial characteristics of nanoclay-based food packaging materials. Finally, it discusses the migration of nanoclays, toxicity levels, and the legislation associated with the application of nanoclays. Graphical abstract

“…The fact that gelatin films are more soluble than Pinhão flour films is due to the greater availability of hydroxyl groups with increasing glycerol concentration. 39,57 This lower solubility of PF films can be attributed to the favorable interaction between the components, maintaining the compounds, avoiding the generation of large pores, and decreasing their solubility. 3,10 In addition, the decrease in the solubility of the films may be related to the presence of the fibers and bioactive compounds present in the Pinhão husk, which may be related to the formation of crosslinks in the polymeric matrix that contributed to the reduction of the hydrophilic character and polar groups in the film.…”

“…In contrast, studies using cellulose nanofibers/ nanocrystals reported improvements in the permeability to water vapor, tensile strength, and elasticity of films. 11,21,31,[33][34][35][36][37][38][39] Some studies have been using nanomaterials from less explored sources, such as ramie nanofibers. 40 Other studies point to using materials with superior granulometry prepared by milling, among which we mention grape stalks, 10 cassava bagasse 20 and Pinhão husk.…”

In this study, the use of Pinhão husk as a source of reinforcement material for development of edible films, where the Pinhão seed flour and bovine gelatin were used as matrices for the films. Mechanical properties, water vapor permeability, solubility and opacity, microstructure, and thermal degradation characterized the films produced. The films presented homogeneous and cohesive structures. Pinhão husk content positively affected film properties by increasing tensile strength (TS) and decreasing water vapor permeability (WVP), with Pinhão flour film formulations (5.0% Pinhão flour, 1.2% glycerol, and 0.4% Pinhão husk) and gelatin (5.0% gelatin, 2.0% glycerol, and 0.4% Pinhão husk) those that presented the best results (5.06 MPa for TS and 0.14 g.mm/kPa.h.m2 for WVP) and (3.88 MPa for TS and 0.28 g.mm/kPa.h.m2 for WVP), respectively The thermal degradation study revealed that the films are stable at temperatures below 150°C, losing only free water and volatile compounds of low molecular weight. Pinhão husk can reinforce films, making them suitable as biodegradable and edible packaging materials for eco‐friendly food products. This contributes to the circular economy, preserves biodiversity, and reduces plastic waste, offering promising sustainable packaging solutions.

“…Biobased polymers are the most promising materials that are partially or completely biodegradable and synthesized from plants or microorganisms through metabolic or biochemical engineering processes. 14 In addition, according to their origin, biobased polymers are classified into 3 types; these are (1) extracted from biomass: (I) Polysaccharides (starch, 15 cellulose, 16 chitosan, 17 carrageenan, 18 pectin, 19 and alginate 20 ), (II) Proteins (gelatin, 21 collagen, 22 zein, 23 and keratin 22 ) and (III) Lipids 22 ; (2) synthesized from biobased monomers (PLA 24 and polyesters); and (3) attained from microorganisms (PHAs 25 and bacterial cellulose). 26 All these materials are abundant, renewable, and ecological.…”
