Effects of 7.5% potassium sorbate and/or 1% ascorbic acid dip on shelf-life of physicochemical quality of chicken parts stored at $4^{circ}C$ was investigated. There was no remarkable difference in the physicochemical changes between 1% ascorbic acid dipped chicken pairs and untreated chicken parts. 1% ascorbic acid dip retarded lipid oxidation slightly. 7.5% potassium sorbate dip reduced dip loss, inhibited the decrease of water holding capacity and retarded lipid oxidation and protein deterioration. Compared with 7.5% potassium sorbate dip alone, dual treatment of 7.5% potassium sorbate and 1% ascorbic acid showed no significant difference in the physicochemical quality such an pH, drip loss, water holding capacity, shear force value and volatile basic nitrogen cotents while lipid oxidation was retarded more effectively. Reduction in relative contents of linoleic acid in dual treated chicken was significantly retarded.
