“…Nanocomposite active packaging is a major topic in dairy nanotechnology. Nanostructured antimicrobials can be valuable to promote a controlled diffusion, improve cost-effectiveness and increase shelf life, but limited data about the migration of nanoparticles to the food matrix and their potential toxicity have attracted significant concern [ 94 , 95 ]. Besides the usual concerns on metallic NPs, delivery systems based on nanostructured lipids have gained attention as encapsulated lipophilic substances apparently change the general absorption pathway and may cause unknown effects [ 96 , 97 ].…”

In the food sector, one of the most important economic activities is the dairy industry, which has been facing many challenges in order to meet the increasing demand by consumers for natural and minimally processed products with high quality. In this sense, the application of innovative and emerging technologies can be an interesting alternative, for example, the use of nanotechnology in packaging and as delivery systems. This technology has the potential to improve the quality and safety of dairy products, representing an interesting approach for delivering food preservatives and improving the mechanical, barrier and functional properties of packaging. Several applications and promising results of nanostructures for dairy product preservation can be found throughout this review, including the use of metallic and polymeric nanoparticles, lipid-based nanostructures, nanofibers, nanofilms and nanocoatings. In addition, some relevant examples of the direct application of nanostructured natural antimicrobials in milk and cheese are presented and discussed, as well as the use of milk agar as a model for a preliminary test. Despite their high cost and the difficulties for scale-up, interesting results of these technologies in dairy foods and packaging materials have promoted a growing interest of the dairy industry.

“…Although nanoparticles have high efficacy for disease suppression, their environmental consequences have prompted certain concerns, such as the risk of nanomaterials entering the food chain through the air, water, and soil during usage . Therefore, in vitro systems based on biochemical and cell culture methods and in vivo evaluation using lower organisms and animal models are used to assess the potential toxicity of clay-based nanocomposites . The interaction between diverse components of clay-nanocomposite is less explored but likely to gain attention in the near future.…”

Clay-nanocomposite materials have been widely exploited as drug delivery systems, but their application in agriculture is less explored. In clay-nanocomposite, the combination of nanoclay and the active ingredient (i.e., metal, nonmetal, oxide nanoparticles) can produce a biocompatible and environmentally friendly delivery vehicle of micronutrients, pesticides, etc. for better crop growth. Clay-nanocomposites have been researched to address the problem of nontarget effects of agrochemicals, their leaching into groundwater, and the fast breakdown of sprayed chemicals. Here, we present a review of the synthesis of clay-based nanocomposites and their application as a delivery vehicle for agrochemicals and nucleic acids, as well as their antimicrobial properties. This review would be helpful in identifying and addressing the current issues of the delivery of active ingredients and biological macromolecules for crop protection, improved growth, and sustainability.

“…In efforts to enhance both the processability and functional properties of PHB, researchers are exploring the incorporation of nanoclays into the polymer matrix. A study revealed that nanoclays facilitate not only improved processability but also enhance barrier characteristics by modifying the crystalline morphology [ 34 , 35 ]. Specifically, in a study focusing on PHB nanocomposites containing different types of nanolayered silicates, PHB matrices were successfully reinforced with nanolayered silicates, resulting in improved mechanical and thermal properties, including load-bearing capacity, thermal transition temperatures, and thermal stability demonstrating that the nanocomposites exhibited superior mechanical performance compared to pure PHB [ 36 ].…”

Biobased and biodegradable plastics have emerged as promising alternatives to conventional plastics offering the potential to reduce environmental impacts while promoting sustainability. This study focuses on the production of multilayer blown films with enhanced functional properties suitable for food packaging applications. Films were developed through co-extrusion in a three-layer film configuration, with Polybutylene Succinate (PBS) and Polybutylene Succinate Adipate (PBSA) as the external and internal layers, respectively. The functional layer consisted of Polyhydroxybutyrate (PHB) enhanced with nanoclays Cloisite® 30B at varying weight ratios. Films were also processed by manipulating the extruder screw speed of the functional layer to investigate its impact on the functional properties. Rheology, mechanical strength, and barrier performance were characterised to establish correlations between processing conditions and functional layer blends (Cloisite® 30B/PHB) on the properties of the resultant films. Rheological test results indicated that the system with 5% Cloisite® had the best polymer/nanofiller matrix dispersion. Mechanical and permeability tests showed that by varying the process conditions (the alteration of the thickness of the functionalized layer) resulted in an improvement in mechanical and barrier properties. Furthermore, the addition of the nanofiller resulted in a stiffening of the film with a subsequent decrease in permeability to oxygen and water vapour.
