A control system for controlling the storage of metabolically active produce in a defined confined environment. The control system comprises gas analyzing and pressure measurement means including a control unit for determining an adjusted gas medium composition of the confined environment for protecting the produce against metabolic degradation. An operating/actuating means for adapting the gas medium in the confined storage environment is based on the determined adjusted gas medium composition. The control unit is adapted for determining the adjusted gas medium composition based on a mathematical model of the system that determines a metabolic coefficient of the produce by combining measured changes of gas composition in the confined environment with dynamic pressure changes in the confined space. The value of the metabolic coefficient is used as input for a control algorithm to continuously adjust the gas composition in the confined space in response to the metabolic activity of the produce.

A method and system for storage of respiratory produce includes a storage environment, a gas analyze, a COscrubber, a gas sampling pump, a gas pump for the scrubber, an air supply, an Nsupply and valves for flow control. The control system is a software assisted measurement system and control algorithm that takes into account the gas exchange dynamics of both the produce and the storage environment and a mathematical model for determining the actual respiratory and fermentative rates of the produce. The system is suitable for low oxygen storage of respiratory produce.
