Abstract
This study was conducted to evaluate the effects of adding gradually increasing concentrations of turmeric extract (0, 0.1, 0.2, and 0.4%) to smoked duck meat on its chromaticity, antibiosis, and antiseptic degree against food poisoning bacteria, number of bacteria, lipid rancidity, sensory evaluation, and preference. The brightness, red color intensity and yellow color intensity changed significantly when 0.2% turmeric extract was added and the sodium nitrate concentration was reduced. Additionally, no antibiosis or antiseptic activities against food poisoning bacteria were observed in any turmeric treated samples, whereas the number of bacteria was increased in control samples compared to turmeric treated samples after 10 days of preservation. The TBARS value decreased during storage when turmeric extract concentration increased, resulting in positive sensory evaluation of its color, succulence, taste and hardness. In the preference test, the surface and meat color increased as the concentration of turmeric extracts increased. Hardness was highest at 0.2%, whereas taste was highest between 0.2 and 0.4%. The overall preference test was highest for the 0.2% extract samples. Overall, the results indicated that addition of 0.2% turmeric to smoked duck meat will lead to better nutrition, function, and overall preference.
