This study was designed to evaluate the effects of feral peach (Prunus persica Batsch var. davidiana Max.) sugar extracts (peach extracts) and Gomchwi (Ligularia fischeri) extracts on physicochemical properties of Woorimatdag 1breast marinated with red pepper sauce during cold storage for 18 days. Experimental groups were divided into five groups; CON: marinated breast with basic red pepper sauce, GP15 and GP30: added with 15% and 30% of peach extracts into CON, respectively, GG5 and GG10: added with 5% and 10% of Gomchwi extracts into CON, respectively. Moisture and fat contents of GP30 were lower than those of CON, GG5, and GG10 (P<0.05). Cholesterol content of GP15 was similar to that of CON, while it was lower than the other treatments. GP15 and GP30 showed significantly lower pH than the others. Especially, GP30 showed significantly lower total aerobic bacteria count than other treatment on day 10. During storage, peach and Gomchwi extracts were not significantly effect on meat shear force. Overall acceptability of GP15 was higher than that of GG10 at day 10 and 15 (P<0.05). These results indicated that the treatment of peach extracts has a tendency to improve the storage stability maintaining the sensory preference of marinated Woorimatdag 1 breast compared to Gomchwi extracts. Further study would be needed to identify the specific flavor-enhancing factors of GP treatments.
