A control (samples unwashed and stored at room temperature) was also investigated. The effect of <em>cultivar x ozone treatment</em> interaction on water content losses, total polyphenols content and antioxidant activity was evaluated after 0, 3 and 7 days of storage. Washing with ozonised water and storage under O<sub>3</sub><sup>-</sup> enriched atmosphere allowed higher water retention compared with the control, especially for <em>Violet de Provence</em>. After 3 days of storage in ozone-enriched atmosphere, on average of cultivars, the total polyphenols content and antioxidant activity increased by 11.7% and 5.5%, respectively. By contrast, after further 4 days of storage in ozonised atmosphere, <em>Apollo</em> and <em>Violet de Provence</em> displayed a significant reduction in their level of total polyphenols and aantioxidant activity. The exposure of globe artichoke heads to an ozone-enriched atmosphere should not exceed 3 days aimed at preserving their high nutritional value, with special emphasis on total polyphenols content.
