Thermal treatment is insufficient to inactivate these resistant forms. This study explored the effectiveness of supercritical CO2 (scCO2 ) on its own and combined with lemon (LEO), clove (CLEO), and cinnamon (CEO) essential oils on the inactivation of Clostridium sporogenes (CECT 553) as a surrogate of Clostridium botulinum. In water, the degree of inactivation at 10 MPa after 60 min increased with the increasing temperature, reducing the population by 90% at 40 ◦C and by 99.7% at 80 ◦C. In contrast, when applied to honey, scCO2 did not inactivate Clostridium spores satisfactorily at temperatures below 70 ◦C, which was related to the protective effect of honey. Meanwhile, scCO2 modified with CEOengAtribución 3.0 Españajournal articlehttps://doi.org/10.3390/ pr10112232open access66.0high-pressure carbon dioxidelemon essential oilclove essential oilcinnamon essential oilClostridium sporogenesIngeniería química3303 Ingeniería y Tecnología Químicas
