1. ABSTRACT
The lowest possible oxygen content during CA storage of fruits and vegetables is considerably lower than what
is applied in practice. Fermentation of the stored crops is avoided in this way. However, due to this safety
margin, the maximum yield in product quality is not achieved. Application of the lowest possible oxygen
concentration asks for a system in which the oxygen content can be watched dynamically and corrected
irnmediatly when the stored product starts fermenting. This can be realized by making use of changes in the
respiration behaviour of crops, monitored . by the start of ethanol production. For the development of a
Dynamic Control System (DCS) to obtain the optimal CA storage conditions with respect to produ
