This study was conducted to investigate the relationship between quality factors and freshness or palatability of Hanwoo beef according to storage condition. The drip loss, cooking loss, volatile basic nitrogen (VBN), thiobarbituric acid reactive substance (TBARS), total viable counts (TVC) and sensorial characteristics of Hanwoo beef (raw and cooked) were investigated during storage for 36 d at 0 and 10℃. The drip loss, cooking loss, VBN, and TBARS were increased during storage period. The correlation between these factors and freshness was shown to be highly significant at both 10℃ than 0℃. Especially, correlation of between the cooking loss and freshness of Hanwoo beef showed high significance (p<0.01) at higher storage temperature. The correlation coefficient between factors such as VBN, cooking loss, and TVC and palatability were decreased with increased storage temperature. As a statistical analysis result, a multiple regression equation of Y₁=10.768-0.706X₁ (Drip loss) with R²=0.87 was obtained for freshness evaluation of Hanwoo beef. Also, multiple regression with drip loss (X₁) and TVC (X_5) increased the coefficient of determination for sensorial palatability (Y₂) to R²=0.95 with a regression equation of Y₂=9.702-0.438X₁(drip loss)-0.232X_5(TVC).
