This study was carried out to investigate the antioxidative effect of Kochujang seasoning sauce with the addition of fruit and vegetable extract (FVE) for pork Bulgogi, as well as to establish the optimum mixture ratio of ingredients using mixture experimental design (MED). During 5 months of storage at $-25^{\circ}C$, the thiobarbituric acid (TBA) values of the seasoned pork containing soy sauce (control), Kochujang added group (KG) and Kochujang and FVE added group (KFVEG) were remarkably lower than that of unseasoned pork. Among the seasoned porks, the antioxidative effect of KG was much higher than the control. Moreover, TBA values of KFVEG were significantly lower than those of KG. Therefore, the lipid oxidation stability of seasoned pork Bulgogi was improved by the addition of Kochujang, red pepper powder and FVE into the seasoning sauce. When Kochujang was used in seasoning sauce, the preference scores of pork Bulgogi increased with the increasing amount of red pepper powder and FVE. The optimum mixture ratios of seasoning sauce for pork Bulgogi established by the MED were Kochujang 0.04, red pepper powder 0.20, FVE 0.39 and water 0.37.

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.
