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 (25°C) and during storage at 10°C for 12 days, and it increased the shelf -life of seafood during storage at 10°C 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
