Özet
This study was undertaken to evaluate the efficacy of gaseous ozone for the degradation of aflatoxin B-1 (AFB(1)) and inactivation of indigenous microflora in poultry feed. Feed samples were treated with continuous stream of two different constant concentrations (2.8 and 5.3 mg/L) of ozone at room temperature up to 240 min. The initial AFB(1) level in artificially contaminated feed samples, determined as 32.8 mu g/kg, decreased by 74.3 and 86.4% after 240 min of exposure at 2.8 and 5.3 mg/L, respectively. At the both ozone concentrations, 240 min exposure was reduced the aerobic plate and yeast and mold counts below the detection limit (<10 CFU/g) with a reduction more than 3.2 and 2.7 log, respectively. The thiobarbituric acid reactive substances (TSARS) assay indicated that no significant (P >= 0.05) increase occurred in the level of lipid oxidation in feed samples during 120 min ozonation at 2.8 mg/L. At the end of the 240 min of exposure at 2.8 and 5.3 mg/L, initial TBARS concentration, determined as 2.4 mg/kg, reached to 4.4 and 5.3 mg/kg with a significant (P < 0.05) increases, respectively. The results presented in this study suggested that significant (P < 0.05) reductions in the AFB(1) level and microbial population can be achieved in poultry feed by ozonation with an acceptable changes in lipid oxidation.
