Abstract
The characteristics of blown color of Korean traditional soy sauces under different processing conditions were investigated in this research. As for meju type, traditional and modified mejus were used. The samples were produced from four levels of aging time. 0 day, 60 days, 120 days and 180 days in both clay jar and glass jar. Color intensity of soy sauce was probed with different mothods. In terms of colorcharacteristics, the absorbance at 420 nm seemed to reflect the brown color intensity of soy sauces. UV-VIS spectra of the soy sauce with traditional meiu revealed that the absorbance at 235 nm was produced during the soaking period whereas that at 410 nm was created during the aging process and only round in the spectra of soy sauce aged for 180 days. As for the soy sauce with modified meiu, the maximum absorbance was focused at 235 nm which were prepared during soaking period.
