The retention time and the intensity of condensation at the fruit
surfaces, at the inner film surface and at the inner tray walls were
identified as main qualities to describe the dynamics of condensate
formation in film packagings of fruit and vegetables at fluctuating
external temperatures. Based on the chosen experimental design,
condensate formations which were time-delayed and superimposed
with varying local and temporal intensities on the surface
of the fruit, on the inner film surface, and on the inner tray walls
could be measured under changing ambient conditions. Condensation
processes inside the plastic film packaging were present even
at temperature differences as low as 3 K.
