Abstract
Seok-jang is one of traditional seasonings prepared by solidification of the mixture of say sauce and salt for long period of aging time. In this study, the physiochemical properties of Seok-jang were investigated for the substitution of solar salt. Seok-jang exhibited highest mineral (P, Na, Fe, Mn, and Al) contents than those of solar salt and soy sauce, while showed lower soluble solids content than that of soy sauce. Seok-jang also exerted the highest pH value 7.70 compared to solar salt and soy sauce. Whereas magnesium and calcium contents of solar salts were 2.90 and 0.26 ppm, which were significantly higher than those of Seok-jang. In color values, L* value was highest in solar salt and lowest in say sauce, While the highest a* and b* value were 6.19 and 18.2 observed in Seok-jang followed by a solar salt and soy sauce. On the other hand, less amount of insoluble solid and sand powder content were 0.03 and 0.07% found in Seok-jang, respectively. In conclusion, Seok-jang was suitable for the potentional substitution of natural salt ingredient.
