This paper provides a specific review of available technologies which share as common core the deliberate formulation of the overhead atmosphere, with the goal of extending the useful life of fresh fruits and vegetables. Classical and novel technologies pertaining to controlled and modified atmospheres are duly presented and discussed, in terms of principles, advantages, limitations and applications. Finally, updated recommendations encompassing controlled and modified atmospheres are listed.engExtension of shelf lifePackagingOverhead atmosphere compositionPostharvestFoodjournal article
