Fresh fruits and vegetables are perishable commodities requiring technologies to extend their postharvest shelf life. Edible coatings have been used as a strategy to preserve fresh fruits and vegetables in addition to cold storage and/or controlled atmosphere. In recent years, nanotechnology has emerged as a new strategy for improving coating properties. Coatings based on plant-source nanoemulsions in general have a better water barrier, and better mechanical, optical, and microstructural properties in comparison with coatings based on conventional emulsions. When antimicrobial and antioxidant compounds are incorporated into the coatings, nanocoatings enable the gradual and controlled release of those compounds over the food storage period better than conventional emulsions, hence increasing their bioactivity, extending shelf life, and improving nutritional produce quality. The main goal of this review is to update the available information on the use of nanoemulsions as coatings for preserving fresh fruits and vegetables, pointing to a prospective view and future applications.

Background: Households in areas of socio-economic deprivation are more likely to consume diets low in fruit and vegetables. Fresh Street is a place-based fruit and vegetable voucher scheme with vouchers redeemable with local independent (non-supermarket) vendors. Paper vouchers are offered to all households in a geographical area regardless of household type, size, or income with no requirement to demonstrate need.

Natural apple essence (AE) has been widely used as a flavor enhancer due to its distinct aroma and taste, but its high volatility restricts its broader applications in food products. This study addresses the need for an effective microencapsulation technique to overcome the volatility of AE. The objective was to optimize and characterize the AE microencapsulation using β-cyclodextrin (β-CD), gum arabic (GA), and montmorillonite (MMT) as wall materials.

Fruit preservation materials play an instrumental role in preventing fruit deterioration and extending shelf life. However, existing fresh-keeping materials often prove inadequate in simultaneously achieving antibacterial properties, maintaining freshness, antioxidant effects, good biocompatibility, and prolonged fruit shelf life. Therefore, we present the first preparation of a natural polysaccharide spray hydrogel (Q/O/Zn hydrogel), loaded with chlorogenic acid‑zinc nanoparticles (CA@ZnNPs), utilizing quaternary ammonium insect chitosan (QECS) and oxidized pullulan (OPUL) for the preservation of perishable fruits.

Global warming and declining rainfall in recent years have led to increased water and soil salinity in Iran agricultural lands. To address these challenges, greenhouse cultivation, particularly soilless culture, emerges as a critical solution for mitigating the effect of soil salinity and water scarcity on vegetable plant production in Iran. The aim of this experiment was to compare the growth and physiological responses of cucumber plants cultivated in both soil and soilless systems, using three distinct nutrient solutions.

Salinity stress disrupts water uptake and nutrient absorption, causing reduced photosynthesis, stunted growth, and decreased crop yields in plants. The use of indole acetic acid (IAA), arginine (AN), and mango fruit waste biochar (MFWB) can be effective methods to overcome this problem. Indole acetic acid (IAA) is a natural auxin hormone that aids cell elongation and division, thereby increasing plant height and branching.
