Abstract: Fruits and vegetables with their rich contents of vitamins, minerals, dietary fibers and anti-oxidants are the “protective foods” and considered as “nature’s capsules” for health. To derive maximum benefits from these bountiful gifts of nature for our nutrition and well being, they are to be produced with their best qualities and are to be preserved and protected from deterioration in both quality and quantity. The quality of horticultural produce at harvest has a decisive influence on its post harvest quality. The initial quality at harvest cannot be improved to any grater extent but can be maintained after harvest by proper post harvest management. Post harvest management operations include pack house practices like washing, sorting, grading, packing, pre-cooling etc., and adoption of refrigerated transport, pre-treatments, storage at optimum conditions, including refrigeration, modified and controlled atmosphere storages and proper marketing practices. Post harvest treatments to delay ripening, reduce the weight loss, reduce rotting and spoilage and extend storage life of fruits and vegetables have been standardized/developed. Post harvest treatments with growth regulators, ethylene action inhibitors significantly delay the softening, colour development and ripening of the fruits and vegetables. Hot water treatments and treatments with permissible fungicides, control the post harvest spoilage and result in better qualities. Edible coating and wax treatments reduce weight loss during storage. Modified atmosphere packaging and individual shrink-wrapping greatly reduce weight loss and ripening, retard compositional changes and extend storage life of fruits and vegetables to a considerable extent even without refrigeration. Simple storage structures developed on evaporative cooling can extend storage life of these perishables with maintenance of quality. The major emphasis is on development “Integrated Post Harvest Management of Fruits and Vegetables” which are affordable, adoptable, by the industries and practiced by growers and rural oriented and aim at safety and quality assurance along with minimization of losses and extension of storage life.
