Mulberry was added to bulgogi marinade sauce at concentrations of 5, 10, 15, and 20%. Moisture content, crude ash, crude protein, and crude fat in the control group were 62.2~62.6%, 3.5~3.6%, 2.2~2.4%, and 1.5~1.6%, respectively. The moisture contents significantly increased with mulberry content. Crude ash, protein, and fat contents relatively decreased as the amount of mulberry in the sample increased. DPPH radical scavenging activity of fresh mulberry was also measured. Fresh mulberry showed higher antioxidant activity in the marinade, and it increased with the mulberry content. Color L, a, and b values of the marinade containing 5% mulberry were 25.41, 3.1, and 4.3, respectively, and all values significantly decreased as the amount of mulberry in the marinade increased. Sensory evaluation of bulgogi marinade was performed by trained panelists. Bulgogi marinade prepared with 15% mulberry content showed a significantly higher score in the sensory evaluation.

This study investigated the sensory characteristics of Bulgogi sauce and Bulgogi added with various amounts (0, 25, 50, 75, 100 %) of licorice extract used as sugar. The color values, $^{\circ}Brix$, pH, attribute difference and acceptance of the samples were tested. As for the color of the Bulgogi sauce sweetened with various % of the licorice extract, a higher percentage of the licorice extract showed a higher L-value. In addition, the $^{\circ}Brix$ of the Bulgogi sauce significantly increased in conjunction with additional licorice extract, although the pH did not show any differences. Attribute difference analysis results revealed that the transparency of the Bulgogi sauce and gloss of the Bulgogi were highest in the sample containing 100% of licorice extract. The sweet odor, both for the Bulgogi sauce and Bulgogi, increased with higher amounts of licorice extract, as well as the scent of the herb. Furthermore, Bulgogi sauce with 50% licorice extract resulted in the highest score for umami taste. The aftertaste of both the Bulgogi sauce and Bulgogi appeared to be the highest with 75% of licorice extract. Bulgogi marinade prepared with 50% of licorice extract possessed the significantly highest score in the overall acceptance test.
