“…It can be applied in other food preparations, such as meat, fish, butter, cheese, and beverages (Bown 2001;Meyers 2003;Piva et al 2021), while essential oil is employed as a food preservative and flavoring agent (Li and Chang 2016). The nanocomposite film prepared from O. basilicum seed mucilage can be used for food packaging (Rohini et al 2020). Further, the essential oil of O. basilicum has been applied to prepare edible coating and food packaging system to increase food shelf-life (Amor et al 2021;Mohammadi et al 2021).…”

Ocimum species represent commercially important medicinal and aromatic plants. The essential oil biosynthesized by Ocimum species is enriched with specialized metabolites specifically, terpenoids and phenylpropanoids. Interestingly, various Ocimum species are known to exhibit diverse chemical profiles, and this chemical diversity has been at the center of many studies to identify commercially important chemotypes. Here, we present various chemotypes from the Ocimum species and emphasize trends, implications, and strategies for the quality and yield improvement of essential oil. Globally, many Ocimum species have been analyzed for their essential oil composition in over 50 countries. Asia represents the highest number of chemotypes, followed by Africa, South America, and Europe. Ocimum basilicum L. has been the most widespread and well-studied species, followed by O . gratissimum L., O . tenuiflorum L., O . canum Sims, O . americanum and O . kilimandscharicum Gürke. Moreover, various molecular reasons, benefits, adverse health effects and mechanisms behind this vast chemodiversity have been discussed. Different strategies of plant breeding, metabolic engineering, transgenic, and tissue-culture, along with anatomical modifications, are surveyed to enhance specific chemotypic profiles and essential oil yield in numerous Ocimum species. Consequently, chemical characterization of the essential oil obtained from Ocimum species has become indispensable for its proper utilization . The present chemodiversity knowledge from Ocimum species will help to exploit various applications in the industrial, agriculture, biopharmaceutical, and food sectors.

“…The addition of MMT increases the maximum value of tensile stress (TS) and decreases the percentage of deformation (%E), generating more rigid and less deformable films with a higher young modulus (YM) compared to blank, attributed to the strong interfacial interaction created between starch and MMT. The improved mechanical property has been attributed to various reasons, such as the resistance to deformation force exerted by the clay with its high surface area and the hydrogen bonds that formed between the hydroxyl groups of the starch and the MMT (Rohini et al, 2020;Vaezi et al, 2019;Llanos et al, 2018). The addition of PCL to the starch matrix provoked a twofold effect on the mechanical response of the film: matrix plasticization effect (Tg decrease of starch) caused by the small PCL miscible fraction and matrix discontinuity due to the non-compatible PCL fraction (Averous et al, 2000;Matzinos et al, 2002).…”

“…The addition of PCL caused a decrease of this parameter by 0.5 MPa. In Figure 1b, the increase in the concentration of MMT drastically decreases the percentage of maximum deformation that the films undergo before breaking; this effect is linked to the fact that the films become more rigid with the addition of clays because of chemical interaction reduce de molecular motion (Rohini et al, 2020). For the formulation with MMT at 5 %w/w, the maximum deformation was approximately 30%.…”

“…The authors attributed the observed effect to H-bond formation between the montmorillonite and CMC, limiting the free hydroxyl groups for water absorption [ 64 ]. Other examples of montmorillonite-reinforced materials with improved barrier and mechanical properties include mucilage/montmorillonite films [ 65 ] and thermoplastic starch/montmorillonite/zinc oxide (ZnO) films [ 66 ]. Some examples of polymer nanocomposites barrier properties are listed in Table 1 .…”

There is a strong drive in industry for packaging solutions that contribute to sustainable development by targeting a circular economy, which pivots around the recyclability of the packaging materials. The aim is to reduce traditional plastic consumption and achieve high recycling efficiency while maintaining the desired barrier and mechanical properties. In this domain, packaging materials in the form of polymer nanocomposites (PNCs) can offer the desired functionalities and can be a potential replacement for complex multilayered polymer structures. There has been an increasing interest in nanocomposites for food packaging applications, with a five-fold rise in the number of published articles during the period 2010–2019. The barrier, mechanical, and thermal properties of the polymers can be significantly improved by incorporating low concentrations of nanofillers. Furthermore, antimicrobial and antioxidant properties can be introduced, which are very relevant for food packaging applications. In this review, we will present an overview of the nanocomposite materials for food packaging applications. We will briefly discuss different nanofillers, methods to incorporate them in the polymer matrix, and surface treatments, with a special focus on the barrier, antimicrobial, and antioxidant properties. On the practical side migration issues, consumer acceptability, recyclability, and toxicity aspects will also be discussed.
