ABSTRACT

Caring, protecting and conserving the environment for future generations of plants, human beings and other creatures has become a priority of today’s world. The existing food laws have brought about several desirable changes in logistics of postharvest handling and value chain of fresh horticultural produce. Synthetic pre and post storage treatment agents/molecules have been replaced with ecofriendly products. In last couple of years, some environmental and consumer friendly post harvest treatment materials like nitric oxide (NO), salicylic acid, methyl jasmonates (MeJA), ethanol, polyamines, 1-Methylcyclopropene, ozone, edible waxes, essential oils, biocontrol agents and irradiation are gaining popularity across the globe. These ecofriendly agents are equally effective over traditional synthetic chemicals in respect of bringing down the physiological and biochemical changes in the harvested produce. Application of nitric oxide, salicylic acid, methyl jasmonates (MeJA), ethanol, polyamines, 1-Methylcyclopropene, ozone, edible waxes, essential oils, biocontrol agents and irradiation have been proved effective in minimizing storage disorders likechilling injury (CI), scald; fungal diseases like stem-end rot, blue mold rot, green mold rot, anthracnose; regulation of ripening and senescence, etc. Quality traits of fresh produce were also found retained for longer period in fruits by application of these compounds.
