摘要

Process for treating post harvest potatoes that may be or be infected by the solanivora key, comprising the direct and continuous application of ozone in high concentration and basis weight regulated on potato, infected or not, maintaining said ozone concentration throughout the application in a period of at least 48 hours and said potato stored in a chamber at controlled temperature of 7 being. Ozone is produced from oxygen enriched to 96% purity by an oxygen concentrator capable of achieving an oxygen purity of 96%. To avoid saturating the atmosphere and keep the same concentration of ozone throughout the application, there is provided an exhaust outlet in the chamber so as to maintain a continuous stream.
