    The aim of this research work was to study the effects of a postharvest treatment with gaseous ozone on the postharvest quality of Andean blackberries. The methodology developed was based on a quantitative, experimental approach, using the modalities of field and bibliographic research. The laboratory analyses were carried out through laboratory tests for both the physical-chemical and the sensory characteristics of the blackberries exposed to different concentrations of ozone: Control sample, 0,4; 0,5; 0,6 and 0,7 ppm. The results were recorded daily in record sheets and tasting sheets. In all the tests, the ozone generated significant effects (p less than 0,05) in the postharvest quality of the blackberries, identifying that the most effective concentrations were 0,5 and 0,7 ppm of ozone in air.
