Defence Food Research Laboratory (DFRL)

Defence Food Research Laboratory (DFRL)


The Defence Food Research Laboratory (DFRL) came into being on 28th December 1961 under the aegis of Defence Research and Development Organization (DRDO), Ministry of Defence, Government of India, at Mysore especially to cater to the varied food challenges of Indian Army, Navy, Airforce and other paramilitary forces.

Our troops often operate in far-flung inhospitable treacherous terrains under inclement and hostile weather conditions. In such operational situations, not only are they deprived of the fresh produce needed to sustain life processes, even normal regime of cooking becomes extremely cumbersome and difficult for them.

The R & D efforts at DFRL are aimed at designing and engineering lightweight, convenience pack rations for Army, Navy, Air Force and other paramilitary forces. These pack rations do not require any elaborate cooking or preparation at the consumer’s end and remain shelf-stable under varying climatic conditions for periods ranging from 6 months to 1 year when packed properly. This is the only Laboratory, which is exclusively engaged in Research and Development in the field of Food Science and Technology for Defence Forces. Prior to the inception of DFRL, the laboratory functioned as a Food Group within the precincts of Defence Science Laboratory, Delhi.

DFRL, through the dedicated efforts of its scientists and technologists, over the last four decades, has been able to conserve, preserve, stabilize, design, fabricate and engineer a vast array of food products of Indian dietary which are not only shelf stable under all weather conditions but also deliver adequate nutrition and energy to keep the morale of our Service personnel high at all times.

Many of the DFRL foods, born out of innovative state-of-the-art technologies, lend themselves eminently suitable to industrial scale commercial exploitation by enterprising entrepreneurs of different genre.
