Fresh minced beef samples were inoculated with (~ 106 CFU/ml) (6 log CFU/g) of Staph. aureus Initial counts of Staph. aureus in minced beef samples immediately after inoculation were (10.86±5.18 log CFU/g). Essential oils of clove (Syzygium aromaticum) and rosemary (Rosmarinus officinalis) (%v/g) were added to the minced beef samples to achieve final concentrations of 1, 1.5 and2%. Sensory (color, odor and texture) and bacteriological (Staph. aureus counts) analyses were conducted after 1, 2, 3, 4.5.6. 24 hrs, 2nd, 3rd and 6th day during cold storage at 4°C. clove oil (2%) group give the best effectiveness with a significant advantage in extend shelf-life of refrigerated minced meat to 5 days compared to all groups specially control ones (3 days) | ||||
