Abstract
The antibacterial activity of Pulicaria inuloides and Pulicaria crispa essential oils was tested against Listeria monocytogenes, Escherichia coli and Staphylococcus aureus using agar disc diffusion and microtiter broth microdilution assays. PIEO, the essential oil from Pulicaria inuloides, inhibited all tested microorganisms with a minimum inhibitory concentration (MIC) of 5.7, 0.12 and 5.11 mg/ml against Listeria monocytogenes, Escherichia coli and Staphylococcus aureus respectively. PCEO, the essential oil from Pulicaria crispa, showed a lower inhibition for all of the tested microorganisms. The present study evaluated the impact of PIEO on L. monocytogenes, E. coli, S. aureus and tap water (control) inoculated in fish fillets. Results indicated that PIEO eliminated most of L. monocytogenes, E. coli, S. aureus and SPC immediately after treatment at time zero (25C) and during storage at 10C for 12 days, and it increased the shelf -life of seafood during storage at 10C compared with the tap water, whereas SPC counts were high than 7 log CFU/g at the end of storage. The sensory evaluation of fillet fish treated with Pulicaria inuloides essential oil were acceptable by consumers at the level of 0.1 g/100g EO. Fish purchased from supermarkets in Wuxi province, Jiangsu, China, were maintained with good hygiene practices and health conditions, whereas fish purchased from local markets were not.
