The more omija extracts were added, the higher $^{\circ}Brix$ was found. (3) Color : The heavier weight of omija were added, the less L value was found; however, a, b values were increased. Secondly, the results of sensory evaluation based on authentic tastes of demi-glace sauces with the different levels of omija added were as follows; In terms of aftertastes and overall acceptability preference of demi-glace sauces, males and females preferred 2% added omija sauces.
