ABSTRACT
Food and agriculture are directly related to human life, and the rapidly growing human population increases the demand for more horticulture products. Several approaches have been proposed to control pre-harvest and postharvest factors, which lessen the deprivation of postharvest shelf life in crops. Among these, nanotechnological intervention could increase agricultural production efficiency and reduce postharvest waste by improving the longevity of horticultural products. At the same time, the security and safety of fresh produce have also become a global concern as fruits and vegetables are perishable in nature due to microbial attack, moisture, degradation, and physical and chemical contamination. Among the most explored nanoparticles, silver nanoparticles (AgNPs) exhibit attractive antimicrobial potential against multiple commensal and pathogenic strains, antioxidant, and anti-ripening activities due to their peculiar properties, leading to enhanced surface reactivity. Additionally, AgNPs have been explored for the controlled release of additives and improving the overall quality, mechanical properties, processability, and shelf life of crops. In this chapter, the authors describe the use of AgNPs in the postharvest biology of horticultural products, particularly by controlling the growth and development of microbial pathogens and its application in developing nanopolymer-based food packaging, edible coatings, food additives, and nanosensors. Furthermore, the possible issues related to toxicity and safety of AgNP-doped horticulture management are also discussed.
