| Abstract | : | This study was designed to evaluate the bacteria counts and oxidative properties of chicken breast inoculated with Salmonella typhimurium(ST) exposed with gaseous ozone during storage. Chicken breast was contaminated withSTby immersing on peptone water contained 7 log10 of STper ml. Then, chicken breast was subjected to gaseous ozone exposure (10×10-6 kg O3 m-3h-1) at 4°C for 3 d. The gaseous ozone generator was set to on for 15 min and off for 45 min per hour during storage. Gaseous ozone exposure significantly reduced (p<0.05) counts of three bacterias over storage regardless of STinoculation. The decrease of ST, total aerobic and anaerobic bacteria counts ranged from 0.4-1.3 log10, 0.8-1.8 log10 and 0.5-1.7 log10 respectively. Gaseous ozone exposure significantly reduced CIE L* and increased the CIE b* value (p<0.05) on 3 d and 2 d of storage respectively regardless of STinoculation.Gaseous ozone exposure significantly inhibited CAT and GSH-Px activity (p<0.05) at the end of storage. In accordance, a higher TBARS value (p<0.05) was found in chicken breast subjected to ozone exposure on 3 d of storage. In conclusion, gaseous ozone exposure reduced the bacteria counts in chicken breast started from the beginning of study and affected oxidative properties at last day of study. |
