Fresh fruit and vegetables, when adequately watered in the preharvest
period, have high water contents at the date of harvest,
resulting in high relative humidity in the intercellular spaces, at
the produce surface and in the boundary layer of the produce (Fockens
and Meffert, 1972; Maguire et al., 2003). Even small fluctuations
in temperature of the surrounding air lead to condensation
of water on relevant surfaces as a consequence of temperatures
falling below the dew point
