Vibriocidal GOCHUJANG was manufactured using extract of natural products and green tea. Antioxidative capacity of natural products and combination of natural products was measured with Oxidation-Reduction Potential (ORP) system value. Inhibitory ability of vibriocidal GOCHUJANG was compared with Inhibition Zone Diameter (IZD) values. Phellodendri cortex, Schizandrae fructus, Theae folium, Scutellaria baicalensis george and Acanthodanacis cortex and combination of these natural products were showed higher antioxidant capacity and inhibitory effect against V. parahaemolyticus. Two kinds of combinations, A combination was composed of Phellodendri cortex, Schizandrae fructus, Theae folium, Scutellaria baicalensis george, and B combination was consisted of Acanthodanacis cortex and A combination, were presented higher inhibition ratio with IZD values as 1.57±0.0051 and 1.56±0.0071, respectively. Vibriocidal GOCHUJANG was prepared based on A and B combination with their higher IZD value as 1.76±0.0103 and 1.79±0.0103, respectively. When vinegar was added to A and B based GOCHUJANG, their IZD value was more higher as 2.15±0.0071 and 2.44±0.0086, respectively. B combination based GOCHUJANG was exhibited higher inhibitory effect than A based GOCHUJANG. Combination of natural products was more important process for increasing vibriocidal effect. But addition of soybean malt or chitosan or a garlic into A or B combined GOCHUJANG, no different effect was exhibited.
