This study was conducted to investigate the chemical characteristics of different treatments of Gochujang during fermentation at $28^{\circ}C$ C for 100 days, in an effort to improve its taste and organoleptic quality. All treatments of Gochujang saw no effects on total viable bacterial numbers, which kept constant level, during fermentation (2.7~3.22 log CFU/g). Yeast numbers did not change for all treatments in the 100 days of fermentation, but then decreased thereafter, yeast numbers increased during fermentation, showing a level of 0.45~0.42 mg% in the Gochujang with red chilli seed powder on the 100th day of fermentation. DPPH radical scavenging in the early stage of fermentation revealeda tendency to increase in conjunction with an increase in the amount of red chilli seed powder added. Sensory examinations, including taste and preference, of the manufactured Gochujang suggest that the optimal fermentation product results from the condition of 20% added red chilli seed powder.
