Green synthesized nanomaterials as an alternative to restricted chemicals in postharvest preservation of horticultural crops: a review

Synthetic chemicals have been successfully used to control economic postharvest pathogens such as Botrytis cinerea, Penicillium spp., Rhizopus etc., thus reducing losses. However, their active ingredient and co-formulants resulted in use being restricted internationally due health concerns consumers’ requests for safe natural alternatives. As an alternative chemicals, green synthesized nanomaterials incorporated with edible coatings a polymer matrix applied on horticultural crops improve shelf-life Due known antimicrobial activities, plant extracts nanoparticles silver zinc oxide food processing applications. Green sources are stabilizer agents synthesize shape sizecontrolled metal nanoparticles. Thus, eco-friendly produced without using toxic materials cost-effective. Edible form thin layer that prevents oxidation, maintains the product quality, can be safely eaten part of product, does not add unfavourable properties. Studies showed or losses fruit plums, raspberries, etc.
