Cosmeceutical potentials of unpolished rice vinegars containing different amounts of Monascus-fermented soybean powder (soy-koji) were investigated. Four different vinegar types were prepared using 0, 10, 30, and 50% soy-koji addition. Soy-koji vinegar showed stronger cosmeceutical properties, in terms of tyrosinase and elastase inhibitory activities as well as antioxidant capacities, than unpolished rice vinegars (P<0.05). Bioactive effects of soy koji vinegar increased with increasing concentrations of total phenolics and isoflavone aglycones (P<0.05). Results indicate that unpolished rice vinegar supplemented with soy-koji can be an efficient strategy to improve bioactivities in vinegar with associated enhancement of cosmeceutical functionality.
