Abstract: The present invention relates to a method and an apparatus for controlling the atmosphere in a space. In particular, the present invention relates to a method and apparatus for controlling the atmosphere in a closable space at least partially filled with agricultural or horticultural products. In the method according to the invention an optimal oxygen partial pressure and/or an optimal temperature for storing produce is determined based on measurements of solely a carbon dioxide partial pressure.

Abstract: An apparatus for storing perishable products, such as fruit and vegetables, by determining the respiratory quotient, i.e., the production of CO2 and the consumption of O2, of the products during storage in a dynamic controlled atmosphere (DCA) by using a chamber containing a sample of fruits, arranged inside the DCA cell. The respiratory quotient (RQ) is used to adjust the concentration of O2 in the cell so as to induce a slight and controlled anaerobic respiration with slight production of ethanol, which reduces the synthesis and action of ethylene and consequently delays fruit ripening. The present invention can be applied on different fruit species and control of the DCA cells can be in a fully automatic form.
