“…The solution was placed in a rotary evaporator at 40 • C for solvent evaporation. The mean size of the CSNPs in ethanol was approximately 28.42 ± 7.43 nm, while the size of the CSNPs in propolis was 31.50 ± 7.77 nm, according to the results published previously by our research group [20]. Later, the obtained nanoparticles were stored under refrigeration at 4 • C and the concentration used in the coating was 33%.…”

Strawberries have a thin epidermis and a high respiration rate. The use of edible coatings containing chitosan nanoparticles (CSNPs) and propolis (P) has been effective in preserving the shelf life and antioxidant capacity of various fruit and vegetable products. The present research evaluated the effect of coatings with CSNPs and P on the quality, antioxidant compounds, and antioxidant capacity of strawberries. The specific coatings that were evaluated were chitosan (CS), CS+CSNPs33%, CS + CSNPs + P10%, CS + CSNPs + P20%, CS + CSNPs + P30%, and a control with no coating. The variables were weight loss, firmness, total soluble solids (TSS), color, phenols, total flavonoids, antioxidant capacity, and sensory characteristics. An ANOVA and a Tukey test (p ≤ 0.05) were used to analyze the data. Strawberries covered with CS + CSNPs + P10% showed the lowest weight loss (9.77%), while those covered with CS + CSNPs + P20% had the greatest firmness (4.96 N). CS + CSNPs + P coatings at 10%, 20%, and 30% concentrations maintained the antioxidant compounds and antioxidant capacity in the evaluated fruit (28.49 mg GAE g−1, 554.61 μg quercetin g−1, and 92.48% DPPH, respectively). The application of nanostructured coatings did not modify the sensory characteristics of the fruit. Coatings with CSNPs and/or P could therefore be a viable alternative for preserving the quality and antioxidant capacity of strawberries.

“…Gelatinbased edible coatings by propolis were tested, and the active films showed a high antifungal activity against the tested fungus [63]. It was also noted that the incorporation of propolis with chitosan provides higher antimicrobial activity [64,65]. In one of these studies, Correa-Pacheco et al [64] noted that the propolis-containing formulations (10%, 20%, and 30%) had a strong inhibitory effect on Listeria monocytogenes and 10% formulation had a similar effect on Escherichia coli and provided better preservation of strawberries.…”

Propolis, also called “bee-glue,” is a natural resinous substance produced by honeybees from plant exudates, beeswax, and bee secretions in order to defend the hives. It has numerous phenolic compounds with more than 250 identified chemical compounds in its composition, which are also known to significantly vary according to the plant sources and season. Moreover, it has a long history in the traditional and scientific medicine as having antibacterial, anticancer, anti-inflammatory, anti-infective, and wound healing effects since 300 BC. In addition to its nutritional and health-promoting effects, it has been reported to improve the postharvest storability of fresh fruits, vegetables, and processed food products. Herein, the biochemical composition and the efficacy of propolis in maintaining the postharvest storability of fresh food products were discussed to provide comprehensive guide to farmers and food processing and storage sectors and to scientists. This review paper also highlights the important points to which special attention should be given in further studies in order to be able to use propolis to develop biopreservatives industrially and for quality preservation during storage.

“…Incorporation of CSNPs into edible films prepared for strawberry preservation together with 1% chitosan, glycerol, and ethanolic extract of propolis (EEP) has shown an inhibitory effect against FBPs in a concentration-dependent manner [ 92 ]. From these edible films, the higher effect was observed for formulation with 10% EEP, and the details for this film are recorded in Table 4 .…”

Chitosan has emerged as a biodegradable, nontoxic polymer with multiple beneficial applications in the agricultural and biomedical sectors. As nanotechnology has evolved as a promising field, researchers have incorporated chitosan-based nanomaterials in a variety of products to enhance their efficacy and biocompatibility. Moreover, due to its inherent antimicrobial and chelating properties, and the availability of modifiable functional groups, chitosan nanoparticles were also directly used in a variety of applications. In this review, the use of chitosan-based nanomaterials in agricultural and biomedical fields related to the management of abiotic stress in plants, water availability for crops, controlling foodborne pathogens, and cancer photothermal therapy is discussed, with some insights into the possible mechanisms of action. Additionally, the toxicity arising from the accumulation of these nanomaterials in biological systems and future research avenues that had gained limited attention from the scientific community are discussed here. Overall, chitosan-based nanomaterials show promising characteristics for sustainable agricultural practices and effective healthcare in an eco-friendly manner.
