उत्तर
Nitrogen of air is converted to soluble nitrogenous compounds in the soil in the presence of air and moisture. These-are absorbed by plants and converted to plant proteins.Nitrogen being inert or un reactive is filled into food packets to drive out the oxygen.
Hence bacterial growth inside the food package is reduced and thereby the food is well preserved and fresh.
