Abstract

The quality characteristics and antioxidant activities of Yanggeng prepared with different amounts of fermented and aged garlic paste(0, 10, 20 or 30%) were determined. The pH of fermented and aged garlic Yanggeng decreased according to the amount of added fermented and aged garlic paste, whereas the acidity increased. In addition, the lightness of fermented and aged garlic Yanggeng decreased according to the amount of added fermented and aged garlic paste. In the texture analysis, hardness, cohesiveness and springiness of fermented and aged garlic Yanggeng were lower than those of the control. Total phenol content was highest in 30 % fermented and aged garlic Yanggeng. The antioxidant activities of fermented and aged garlic Yanggeng increased according to the amount of added fermented and aged garlic paste. The IC50 value of 30% fermented and aged garlic Yanggeng was 45.1 mg/g for DPPH and 29.6 mg/g for hydroxyl radical. The results of the sensory test showed that Yanggeng with 20% fermented and aged garlic paste had the highest score in appearance, overall preference and texture. Based on these results, it was suggested that the addition of 20% fermented and aged garlic to Yanggeng was appropriate for good food qualities both in terms of the physicochemical and antioxidative activities.
