Cherry is a highly perishable fruit widely appreciated that is only commercialized during a short period. The post-harvest control and monitoring of this fruit is central and essential for optimal consumption in its highest state of quality. The conservation process aimed to inhibit the microbial propagation is usually accomplished by low temperatures and/or variable atmosphere composition.

This paper describes experimental tests conducted in different refrigeration chambers located in industrial and laboratorial facilities. The latter one includes modified atmosphere and controlled atmosphere chambers. The tests were performed with four different concentration of O2 and CO2 in the controlled atmosphere chamber. Fruit samples extracted from each chamber were analyzed at specific residence times and several organoleptic characteristics were analyzed. The results show that the modified and controlled atmosphere maintain the fruit quality in terms of size, color, appearance and firmness, thus increasing their shelf life and food safety.
