Fruits and vegetables obtained from market is contaminated on the surface with residues of Pesticides, Fertilizers and other growth inducing Agro Chemicals. A wash with ordinary water cannot help in removing these harmful contaminants from the food substances. Such contaminated food when consumed has a tendency to store and settle the agrochemicals residues in the body cells. This can lead to long term complications later in life. Sodium permanganate solution helps in cleaning the surface of these food substances by neutralising the harmful pesticides and agro chemicals and rendering it consumable.
Fruits and vegetables tend to rot and putrefy when stored under normal conditions after a certain period, depending on the heat and humidity. This physical change is attributed to the rapid buildup and evolution of Ethylene gas in the fruits and vegetables which accelerates the decaying process. Sodium permanganate effectively oxidizes Ethylene gas in to carbon dioxide and water thereby reducing the Ethylene concentration. This helps in maintaining the freshness of food products and extending the storage time. This application is a great boon to fruit and vegetable suppliers to maintain normal and cold chain deliveries to markets.
