Nanoemulsion edible coating is an emerging technique for creating lipophilic active ingredient delivery systems to facilitate their integration with edible coatings applied over perishable horticultural produce. The current review provides insight into the formulation techniques, characteristics, stability, and application of nanoemulsion edible coatings to improve the quality and shelf-life of perishable horticultural produce. The nanoemulsion coatings on fruits and vegetables are analogous to modified atmosphere packaging, as these coatings create physical barriers to alter the gaseous exchange between the fruit’s internal and external atmosphere, increase the CO₂ concentration, lower the O₂ concentration, and reduce the respiration rate. The nanoscale droplets in the emulsion increase the surface area, allowing for improved coverage of the food surface and improving the barrier to prevent moisture loss, microbiological contamination, and oxidative deterioration and extending the freshness of fruits, vegetables, and other perishable foods. The nanoemulsion-based edible packaging/coating has the potential to revolutionize the food business by addressing issues such as food waste, sustainability, and consumer demand for healthier and longer-lasting products.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100114"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its short postharvest shelf-life results in significant losses, highlighting the need for effective strategies to extend its longevity. This study introduces a novel approach to monitoring and mitigating cassava deterioration by utilizing silver nanoparticle sensors to track hydrogen peroxide (H₂O₂) production, a key indicator of oxidative stress. Four economically viable cassava root cultivars were evaluated for their tolerance to postharvest physiological deterioration (PPD) and quality retention after treatment with various chitosan-antioxidant formulations. The results indicated that the chitosan-quercetin formulation (CS-Q) was the most effective, achieving the lowest average H₂O₂ reduction of 67.7 % compared to untreated samples, followed by chitosan-beta-carotene (CS-BC) at 62.4 %, chitosan-ascorbic acid (CS-AA) at 38.3 %, and chitosan (CS) at 34.8 %. These reductions in H₂O₂ suggest that chitosan-antioxidant treatments can effectively delay PPD and extend cassava's shelf life for up to six months, depending on the cultivar, seasonal factors, and specific antioxidant composition. The successful implementation of this innovation offers a promising solution to delay PPD and enhance the efficiency of the cassava supply chain. Furthermore, this study contributes to the advancement of electrochemical techniques for assessing PPD and demonstrates the potential of chitosan-based materials in improving the postharvest preservation of cassava and potentially other crops.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100115"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wheat growth, productivity and seed quality has been extensively hampered by the aggression of seed-borne pathogens during post-harvest storage. The present work focus on the efficacy of chitosan-based Ag²⁺ nanoparticles (Ag-CNPs) for the management of seed borne pathogens of wheat and their subsequent effects on growth, yield, and quality of harvested seeds. For this, healthy seeds of wheat were nanoprimed with Ag-CNPs and further inoculated with <em>A. flavus</em> so as to induce pathogenic stress. These seeds were sown in pots in a completely randomized block design and plants were raised from both nanoprimed and inoculated seeds, while plants were also raised from non-nanoprimed primed and uninoculated that served as control. Nanoprimed and pathogen inoculated seeds effectively increased vegetative growth such as (132.31 %), fresh weight (1.63-fold), dry weight (1.67-fold), and panicle length (137.03 %). and amplified the number of grains per spike, harvest index, ten kernel weight, and yield/plant, despite of pathogenic interference. Concomitantly, Ag-CNPs nano-priming enhances the harvested seed quality raised from pathogen inoculated seeds plants. The integrated density of the bands obtained in SDS-PAGE of variedly primed seeds revealed that Ag-CNP priming improved wheat's total protein profiling with a denser band intensity. The antioxidant enzymatic activity of CAT, POD, SOD, and NOX was traced maximum in Ag-CNPs primed seeds by 13.52, 7.90, 26.6 and 16.08 units, respectively. Thus, it can be concluded that nano priming with Ag-CNPs mitigated the wheat seeds from pathogenic stress and efficiently increased yield parameters and quality of harvested seeds.</div></div>","PeriodicalId":101029,"journal":{"name":"Plant Nano Biology","volume":"10 ","pages":"Article 100116"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142698550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ZnO-NPs were synthesized from algal (<em>Arthrospira platensis</em>) extract and characterized for their opto-physical properties, confirming size (54 nm), hydrodynamicity (-18.54), amorphous-cubic shape and others features. Fifteen-day-old rice seedlings were primed with 25 ppm ZnO-NPs and exposed to 12 % polyethylene glycol (PEG) mediated drought stress (DS) for 7-days under laboratory conditions.

Plants recorded a significant reduction in root growth, which regained 89.25 % with ZnO-NPs treatments. ZnO-NPs also recovered relative water content (49 %), proline (99.2 %), and improved chlorophyll fluorescence (90.9 %) under stress. Furthermore, drought-induced membrane leakage was stabilized by reducing ionic conductivity through the distribution of wall-bound polyamines. A characteristic feature of fluorescence also reinforced the sustenance of photosynthetic activities by ZnO-NPs under drought. Alternatively, rice seedlings showed regulation of oxidative stress, where lipid peroxidation and protein carbonylation were reduced by 270 % and 178.2 %, respectively. This was observed with the minimization of superoxide and hydrogen peroxide concentrations by regulating apoplastic oxidase activity (117.64 %) with distinct polymorphisms in proteins.
