Abstract: This study was carried out to identify the chemical component of lemon basil and marjoram volatile oils. Also, studying of antioxidant and antibacterial activities of these essential oils and their mixture against S. typhimurium, E. coli, S. aureus and B. cereus by disc diffusion assay. Also, study the effect of different volatile oils and their mixture at 300 ppm on total bacterial count, E. coil and B. cereus counts of inoculated chicken minced meat with E. coil and B. cereus during cold storage at 4?C. Also, identify on selection of the best volatile oils percentage to use in this study. On the other hand, the changes that occurred in the chemical composition, physical, microbiological and sensory properties of chicken minced meat were studied after adding a concentration of 200 and 300 ppm of the previous oils and their mixture to minced chicken at 15 days during cold storage. Either studying of effect the chemical composition, natural properties, freshness, microbiological and organoleptic tests was also studied by soaking chicken drumsticks in cold water with 1000 and 2000 ppm of lemon basil and marjoram and their mixture at 12 day during cold storage. Volatile oils can be sorted according to their antioxidant activity in the following descending order: BHT > lemon basil > mixture > ascorbic acid > marjoram essential oil. Also, volatile oils and their mixtures could be arranged in descending order according to their antimicrobial potency as follows: lemon basil ? mixture of (basil: marjoram1:1) ? marjoram essential oil. Results indicated that, the above-mentioned parameters beside chemical properties (total volatile nitrogen and TBA) and pH values in both chicken minced meat and chicken drumsticks significant affected by concentration of volatile oils compared with control samples during cold storage. Using volatile oils prolonged the shelf life extension of chicken minced meat and drumsticks for 15 and 12 days respectively compared control sample during cold storage,
