Abstract

This study investigated the potential of turmeric (Curcuma longa) crude extract to inhibit Klebsiella pneumoniae in smoked Nile tilapia. Initial tests showed that 5.0 mL of a 0.5 g/mL extract concentration exhibited significant antibacterial activity, resulting in a marked reduction in bacterial growth compared to other treatments. To confirm its effectiveness, the optimal extract from the preliminary test was applied to smoked fish experimentally infected with Klebsiella pneumoniae. The results indicated that the optimal extract had fewer bacterial count up to Day 5 as compared to control, but showed decreased efficacy by Day 5. Further research is needed to enhance its effectiveness and address limitations, promoting sustainable food safety practices in the aquatic food industry.

Keywords: Food safety, Klebsiella pneumoniae, smoked fish, turmeric
