kontrollertatmosfære
Kontrollert atmosfære, often abbreviated as CA, refers to a method of preserving perishable goods, most commonly fruits and vegetables, by altering the composition of the air surrounding them. This process involves carefully controlling the levels of oxygen (O2), carbon dioxide (CO2), and nitrogen (N2) within a sealed storage environment. By reducing the oxygen concentration and increasing the carbon dioxide concentration, the respiration rate of the produce is significantly slowed down. This reduced respiration leads to a decrease in the rate of metabolic processes, thereby delaying ripening, senescence, and the development of spoilage organisms.
The specific gas concentrations used in a controlled atmosphere storage system are tailored to the particular
