The purpose of this study is to evaluate quality characteristics of the Cheonggukjang produced using rice straw-derived Bacillus cereus free starter culture (RiBS1). The Cheonggukjang was prepared in 0.1 and 1.0% inoculum concentrations of starter culture and fermented from 12 hr to 72 hr at 40 and 50℃. Amino-nitrogen contents after 48 hr fermentation were 559.6~590.2 mg% and 393.8~494.0 mg% at 40 and 50℃, respectively. Sensory evaluation showed that the Cheonggukjang fermented using RiBS1 starter for 48 hr at 50℃ was better than the control. And we inspected on B. cereus and biogenic amine in the Cheonggukjang produced using RiBS1 starter. As a results, B. cereus was not detected and histamine and tyramine of biogenic amine were 5.53 ± 0.13 ~ 39.96 ± 0.62 mg/ kg. This research results showed that rice straw-derived B. cereus free starter culture (RiBS1) will be produce the Cheonggukjang with good flavour and taste.
