The objective of the study was to evaluate the quality characteristics of sun-dried Hanwoo beef jerky added with the extract of Citrus junos seib. or Prunus mume. Hanwoo beef shank muscles were sliced, marinated, and sun-dried at $25^{circ}C$, relative humidity of 35%. The physicochemical quality and microbiological safety of the Hanwoo beef jerky aerobically packaged were analyzed during the storage of $25^{circ}C$. The moisture content of beef jerky with Citrus junos seib. was the lowest among the treatments after 20 d. Citrus junos seib. and Prunus mume jerky after 10 d had significantly lower aw than those after 0 and 20 d (p<0.05). The pH values of jerky generally ranged from 5.76 to 5.84. The pH value of Prunus mume jerky was significantly higher than those of other jerky samples (p<0.05). Prunus mume jerky showed significantly lower TBARS value than the others after 20 d (p<0.05). Citrus junos seib. jerky showed a significantly lower lightness ($L^*$), redness ($a^*$) and yellowness ($b^*$) than the others during the storage (p<0.05). Prunus mume samples after 10 d had significantly higher $L^*$, $a^*$, and $b^*$ values than the others (p<0.05). With regard to sensory properties, Citrus junos seib. and Prunus mume jerky showed significantly higher flavor and overall acceptability scores than the control (p<0.05). The extracts of Prunus mume will be used in sun-dried Hanwoo beef jerky as a natural agent to retard lipid oxidation and to improve meat color.
