The invention relates to a method for regulating a controlled atmosphere for the storage of plant products in at least one storage or transport room. The inventive method comprises the following steps: a) measuring, at at least two different intervals, the concentration of at least one trace gas that is produced by the plant products and whose share in the controlled atmosphere is less than 1%, b) deriving from the sequence of at least two measured values the degree of the change in concentration of the trace gas as a measure for the rate at which the plant product produces said trace gas, c) determining the adjustment values for the composition of the controlled atmosphere depending on the degree of the change in concentration of the trace gas, and d) adjusting the composition of the controlled atmosphere in accordance with the adjustment values.
A method to control a controlled atmosphere for the storage of plant products in at least one storage- or transport space, where
The method in accordance with one of the preceding claims, characterized in that the degree of change in the concentration of the C2H6-concentration is determined.
The method in accordance with one of the preceding claims, characterized in that the degree of change in the concentration of an aldehyde, especially that of acetalehyde, is determined.
The method in accordance with one of the preceding claims, characterized in that the CO2-concentration in the controlled atmosphere is not elevated artificially and the degree of change in the concentration of the CO2concentration is determined.
The method in accordance with one of the preceding claims, characterized in that the CO2-concentration, the O2-concentration, the room temperature and/or the air humidity are controlled.
The method in accordance with one of the preceding claims, characterized in that the C2H4-concentration in the controlled atmosphere is controlled.
The method in accordance with one of the preceding claims, characterized in that plant products with the same degree of ripeness are stored in spatial proximity to one another.
The method in accordance with one of the preceding claims, characterized in that a gas analysis method based on the photo-acoustic effect is used to determine the degree of change in the concentration of trace gases.
A use of a photo-acoustic sensor to determine the degree of ripeness of plant products.
