The purpose of this study was to develop the antiallergic and hypoallergic fennented soybean foods without side effect. We manufactured Chungkukjang with addition of herbal (aloe, cinamon, licorice root) extract. Sensory evaluation was performed to evaluate the acceptability by the consumer. Clinical evaluation was performed with 10 atopic dermatitis (AD) patients who showed positive reaction with specific IgE and skin prick test. Cross-over study between nonnal Chungkukjang and Chungkukjang with aloe extract was performed. In sensory evaluation, Chungkukjang with aloe extract obtained best score overall. In clinical evaluation, 7 out of 10 AD patients showed positive reaction to soy-bean and 4 out of 10 AD patients showed positive reaction to normal Chungkukjang. 2 out of 10 AD patients showed positive reaction to Chungkukjang with aloe extract. In conclusion, Chungkukjang could be recommended as functional food with hypoallergic effect. As adding aloe extract to Chungkukjang, hypo allergic effect was increased.
