| Abstract | The inhibitory effect of citronella oil against major species of spoilage bacteria including Staphylococcus au- reus, Klebsiella spp. and Pseudomonas spp. found on the surface of Decapterus maruadsi(semi- dried round scad) was investigated using the broth d ilution method. Citronella oil and its main components d - limonene and linalool were in- troduced into a nutrient broth at volume concentrations (v/v) between 0.5% and 10% to determine the minimum inhibito- ry concentration (MIC) and the minimum bactericidal concentrations (MBC) for the bacteria evaluated. The main com- ponents of citronella oil were determined by gas chromatography -mass spectrometry (GC MS) analysis. The oil exhi- bited activity against all bacteria with a MIC of 1% v/v, while d-limonene showed activity against Pseudomonas spp. at 0.7% v/v and both Staphylococcus aureusand Klebsiella spp. at 0.9% v/v. No MBC was found in this study. Antimi- crobial activity of the citronella oil at the concentration of 1% v/v was further examined on dried fish under storage con- ditions of 4°C and 30°C. Citronella oil was found to be able to extend the shelf life of the semi -dried fish for up to 7 days at 4°C. Both major constituents, d-limonene (86.0%) and linalool (3.2%), represented 89.2% of the citronella oil. These findings showed that the required shelf life of semi -dried fish could be achieved by manipulating the concentration of the citronella oil. |
