The conditions were investigated for optimum cooking time of the soup with four chinese medicines (yakuzen soup).
The following conditions were evaluated: cooking time of 30, 45, 60, 90 min.
The amount of IMP in yakuzen soup for cooking time of 60min was the most of increasing. The amount of reducing sugar and lactic acid in yakuzen soup for every cooking time were almost the same. Japanese were agreeable to the palate of the yakuzen soup which the amount of the Chinese medicine was 1/3 times its weight of recipe in Taiwan.
Sensory evaluation was conducted on the color, sweetness, sourness, bitter, umami, saltiness, body, continuity, mildness and overall preference of yakuzen soup for cooking time.
