“…Several studies have reported on nano-enabled agriculture and have focused on issues such as nano-enabled precision farming [17], nano-enabled farming [12,268], the nano-food industry [269], nano-enabled seed treatments [19,270], nanostructured manganese oxides [271], nano-enabled agrochemicals [88,170,272], and nano-Zn-enabled cropping systems [16]. Along with nano-enabled farming, nano-processed food products have shown great promise for a variety of applications in the food industry [269,273,274] using organic compounds such as chitosan [275], cellulose [276], and proteins [277]. Inorganic nanoparticles have also been used in the food industry, including nano-selenium [278], nano-silver [279], nano-iron [280], nano-zinc oxide [281], and nano-titanium oxide [282].…”

The relationship between agriculture and food is very close. It is impossible to produce adequate crops for global food security without proper farm management. Farming practices represent direct and indirect controlling factors in terms of global food security. Farming management practices influence agro-food production from seed germination through to the post-harvest treatments. Nano-farming utilizes nanotechnologies for agricultural food production. This review covers four key components of nano-farming: nano-mushroom production, protein-based nanoparticles, nano-nutrients, and nanofibers. This provides a comprehensive overview of the potential applications of nanotechnology in agriculture. The role of these components will be discussed in relation to the challenges faced and solutions required to achieve sustainable agricultural production. Edible mushrooms are important to food security because they are a nutritious food source and can produce nanoparticles that can be used in the production of other food sources. Protein-based nanoparticles have considerable potential in the delivery of bioactives as carriers and other applications. Nano-nutrients (mainly nano-selenium, nano-tellurium and carbon nanodots) have crucial impacts on the nutrient status of plant-based foods. Carbon nanodots and other carbon-based nanomaterials have the potential to influence agricultural crops positively. There are promising applications of nanofibers in food packaging, safety and processing. However, further research is needed to understand the impacts and potential risks of nanomaterials in the food production system.

“…The crystalline structures of the synthesized UiO-66-COOH, CS-aerogel, MOF-aerogel-1, and MOF-aerogel-2 were characterized by XRD (Figure 1). For all aerogel networks, the characteristic peak at 11.59 • was attributed to the presence of a hydrated chitosan crystalline skeleton [17,18]. All of the MOF-containing aerogels (MOF-aerogel-1 and MOFaerogel-2) presented the specific diffraction patterns of the UiO-66 series MOFs in the range of 7.2~8.4 • [19,20], in which the single broad peaks observed in the patterns of the two MOF-aerogels were attributed to the presence of the amorphous chitosan substrate.…”

Novel hierarchical metal-organic framework/chitosan aerogel composites were developed for oil bleaching. UiO-66-COOH-type metal organic frameworks (Zr-MOFs) were synthesized and integrated onto a chitosan matrix with different contents and named MOF-aerogel-1 and MOF-aerogel-2. Due to the compatibility of chitosan, the carboxylic zirconium MOF-aerogels not only maintained the inherent chemical accessibility of UiO-66-COOH, but the unique crystallization and structural characteristics of these MOF nanoparticles were also preserved. Through 3-dimensional reconstructed images, aggregation of the UiO-66-COOH particles was observed in MOF-aerogel-1, while the MOF was homogeneously distributed on the surface of the chitosan lamellae in MOF-aerogel-2. All aerogels, with or without immobilized MOF nanoparticles, were capable of removing carotenoids during oil bleaching. MOF-aerogel-2 showed the most satisfying removal proportions of 26.6%, 36.5%, and 47.2% at 50 °C, 75 °C, and 100 °C, respectively, and its performance was very similar to that of commercial activated clay. The reuse performance of MOF-aerogel-2 was tested, and the results showed its exceptional sustainability for carotenoid removal. These findings suggested the effectiveness of the MOFaerogel for potential utilization in oil bleaching treatments.

A biopolymer-based formulation for robust and active food packaging material was developed. This material consisted of a blend of three biopolymers (guar gum−sodium alginate−icarrageenan) reinforced by cellulose nanocrystals (CNC) alongside the integration of silver nanoparticles (AgNPs) with varying sizes. The CNC utilized in this process was derived from cloth waste lint (CWL) generated from a household cloth dryer machine. This CNC synthesis underwent a series of solvent treatments to yield the CNC used in the composite. CNC and AgNPs were incorporated into the tribiopolymeric blend matrix to construct a nanocomposite film that showed excellent tensile strength (∼90 MPa). The nanocomposite film also exhibited antimicrobial activity against Escherichia coli ATCC 25922 and Bacillus cereus MTCC 1272. In this report, it was demonstrated that the zone of inhibition against E. coli and B. cereus depends on the variation of size and amount of AgNPs inside the polymeric matrix. The practical applicability of such a film was also demonstrated by applying it to sliced bread and the enhancement of the shelf life of the raped bread was compared with a control. Thus, the guar gum−sodium alginate−i-carrageenan tribiopolymer blend with a cloth waste lint extracted cellulose nanocrystal composite film is antimicrobial, hence, an excellent candidate as an active packaging film.
