Abstract: Thai salted fish or Pla-kem is a traditional food and popularly taken as side dishes. This work lime, lemongrass and oregano essential oils were evaluated for their effectiveness on post mortem quality of salted fish. Salted fishes were prepared with 60% w/w of NaCl, air dried and covered with coated paper which sprayed by 4 μL/L of each essential oil, physical, chemical, microbiological changes and sensory evaluation were determined for 15 days. The results showed that salted fish coated with all essential oils coated paper have no change on physical appearance but effect on chemical and microbiological changes. The fat content in salted fishes covered with essential oils (lime, lemongrass and oregano) coated paper were significantly decreased to 0.25±0.01, 0.24±0.01 and 0.23±0.01% lipid (p≤0.05) when compared to control on 15th day and were retained the changes of protein. Moreover, salted fish covered with oregano coated paper were inhibited growth of total bacteria through the experiment period, while total fungal, lactic acid bacteria, total coliform and E. coli were ranged on standard. Salted fish covered with lime coated paper had the highest scores on customer acceptance test. Indicated that essential oil might be a potential for maintaining quality of salted fish.
