In this study, antibacterial effect of koruk (unriped grape), lemon and pomegranate juice against Vibrio parahaemolyticus was investigated. For this purpose, approximately 107 CFU/g V. parahaemolyticus were inoculated into mussel samples. Inoculated mussel samples were treated with koruk, lemon and pomegranate juice for 0, 30, 60 and 90 minutes and stored at 4 oC for 6 days. During the storage period, V. parahaemolyticus number, pH and titratable acidity value were determined and evaluated in terms of sensory parameters. As a result of the research, the highest antibacterial effect was detected in the koruk juice groups (P <0.05). On the 0th day of the experiment, the number of V. parahaemolyticus in the groups that were applied koruk, lemon and pomegranate juice were decreased by 2.22-2.64; 1.58-1.85, and 1.44-1.71 log CFU/g, respectively. This downward trend continued on other storage days. Sensory evaluation revealed that pomegranate juice negatively affected the color and appearance of mussel samples (P <0.05). As a result, it has been determined that acidic acidifiers used in home applications, especially the koruk juice has a high antibacterial effect, and can be used for food safety in seafood.
