Ozone application to control odour, bacteria, germ, virus and Mould is widely used in many fields of food processing. To inactivate microbial flora on dried figs ozone was applied in gas form for three and five hours at 5 and 10 ppm. A statistically significant reduction in the total bacterial, coliform and yeast/mould Counts were obtained (P < 0.05). Escherichia coli was not found on the samples. Results indicate that to reduce microorganism count on dried figs minimum three hours treatment at 5 ppm is required. Decrease in total aerobic mesophyllic microorganism and yeast/mould counts was approx. 38% and 72% at this level where all coliform bacteria were inactivated. (c) 2005 Elsevier Ltd.
