The purpose of this study was to investigate the effect of water extract of Gardenia jasminoides (WEGJ) on the sensory qualities, color value and shelf-life characteristics (pH, total no. of Bacillus and TBA value) of cooked rice. The total color difference(ΔE) was increased when WEGJ was added. The sensory dualities of cooked rice added with WEGJ had no significant difference in color, taste and torture compared with control group. The pH value of cooked rice addeded with 250 ppm and 500 ppm of WEGJ was less declined compared with control group. WEGJ at the concentration of 250 ppm and 500 ppm had an antimicrobial activity and WEGJ at 500ppm showed an antioxidant activity in cooked rice.
