Abstract
A method of transporting a quantity of a comestible which may be subject to degradation as a result of respiration during transportation, comprising the steps of: (a) sealing or substantially sealing said quantity of the respiring comestible within a container as hereinbefore described sufficiently to ensure that less oxygen of the ambient air can diffuse into the container than is required for full respiration by the respiring comestible, flushing the container with an oxygen low or oxygen free gas so as to provide a reduced oxygen level in the sealed or substantially sealed container, such flushing occurring before, during and/or after said sealing or substantial sealing, and (b) transporting the container with the respiring comestible therein while (i) monitoring the oxygen level within said container and automatically adjusting the oxygen level as necessary by a positive infusion of ambient air into the container in response to such monitoring towards an optimum or predetermined value or range of values and (ii) monitoring the carbon dioxide level within said container and adjusting the carbon dioxide level as necessary in response to such monitoring towards an optimum or prede…
