Seasoning gochujang sauces were prepared with 0, 10, 20 and 30% concentrated heating chopped garlic (garlic base) and analyzed. These seasoning gochujang storage for 40 days at 37±1℃ and examined for changes in their physicochemical properties. Hunter color L and b-value of seasoning gochujang were decreased slowly till 20 days of storage then increased afterward. The highest pH of the seasoning gochujang was pH 5.22 in the 30% garlic base added group. The titratable acidity increase significantly till 40 days of storage. As the adding ratio of garlic base increased, reducing sugar content was decreased. The amino-nitrogen content was continually decreased during aging up to 40 days. ABTs radical scavenging activity was increased as garlic base addition level was increased. The activity was decreased with passing by storage period, and below 50% at 40 days storage.
