Abstract | Current study aimed to investigate the effects of cinnamon essential oil (CEO) and wheat germ essential oil (WGO) on the chemical and bacteriological quality of oriental sausage. Five batches of beef sausage first as control, second and third groups contained CEO at concentrations of 1% and 2%, while the fourth and fifth groups added with WGO at concentrations of 1% and 2%. The effect of different treatments on pH, total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBA), aerobic plate count (APC), Enterobacteriaceae count, Staphylococcus count and Enterococcus count was studied at zero, 3rd, 6th, and 9th day of chilling at 3±1°C. The mean values of pH, TVB-N and TBA in Control group was 7.03 ± 0.05, 33.46± 0.46 mg/100g and 1.67± 0.03 mg MDA/kg however, it was reduced (p<0.05) in 2% CEO (6.29 ± 0.03, 19.74 ± 0.21mg/100g and 0.85 ± 0.03mg MDA/kg respectively) and 2% WGO (6.36 ± 0.04, 19.99 ± 0.13 mg/100g and 0.89 ±0.025 mg MDA/kg respectively) treated group on 9th day. The mean values of APC, Enterobacteriaceae, Staphylococcus and Enterococcus in control group were 7.23 ± 0.34, 5.43 ± 0.28, 5.12 ± 0.23 and 4.98 ± 0.25 log10CFU/g, while these were reduced (p<0.05) in 2% CEO (6.11 ± 0.31, 4.24 ± 0.26, 4.08 ± 0.24 and 3.98 ± 0.23 log10CFU/g respectively) and in 2% WGO (6.45 ± 0.31, 4.35 ± 0.24, 4.25± 0.23 and 4.08± 0.21 log10CFU/g set respectively) in treated group on 9th day. These results exhibited that CEO and/or WGO at concentration 2% could be added in oriental sausages to retard the chemical changes and decrease the bacterial growth during storage.
