reported lower efficacy of single ozone treatment for the inactivation ofE. coliO157:H7 andSalmonellain unpasteurized apple cider and orange juice compared to a combination
treatment of ozone and antimicrobial agents such as dimethyl
dicarbonate and hydrogen peroxide, which achieved a 5-log reduction.
When apple juice (18 °Brix) was treated with 0.90 g/h ozone gas at
room temperature, about 0.5 and 4.5 log CFU/ml reductions ofE. coli
O157:H7 were observed after 30 s and 60 s treatment, respectively
