Food poisoning is a serious problem that affects thousands of people every year. Contaminated food is usually detectable by odor. The stranger odors of food poisoning are often caused by microorganism that release some gases via its metabolism. Our interest is the improvement of polyaniline and silver nanoparticles composites to achieve developing the off-flavor food gas sensor. PANI and silver nanoparticles (AgNPs)-PANI nanocomposite, including mixing synthesized and core shell synthesized nanocomposite. The AgNPs-PANI nanocomposites successfully synthesized by in-situ chemical polymerization approach. The formation of metallic silver nanoparticles as well as its presence in the nanocomposite were confirmed by UV-Vis spectrometry and SEM analysis. Sensing response of mixing synthesized nanocomposite revealed excellent correlation between sensing response and the various ethanol concentrations at room temperature.
