The Indian Patent Office recently granted a patent to Assam-based scientist Sanjib Kumar Paul, who developed a health and environment friendly edible coating for prolonged shelf life of fruits and vegetables. The patent entitled "Copper (Nanosized)-Chitosan-Menthol Edible Conglomerate Enrobe for Prolonged Shelf-Life of Climacteric Fruit" was accorded for a term of 20 years in accordance with the provisions of the Patents Act, 1970.

Paul made the invention after studying for six years at the Department of Agricultural Engineering under the Triguna Sen School of Technology at southern Assam's Silchar based Assam University.

Paul said: "After a long study and considering all pertinent aspects, we found that a combination of Chitosan (Polysaccharide), copper (nano-sized) and menthol could be an appropriate healthy and user friendly edible coating for at least 28 days shelf life of the fruits and vegetables."
