Abstract: In order to examine the quality of fresh pork on the market, eating quality parameters including cooking loss, shear force, color, pH, total volatile basic nitrogen (TVB-N) and total bacterial count of fresh pork stored at 25, 20, 15, 10 ℃ and 4 ℃ were analyzed comparatively. The results showed that fresh pork stored at 25, 20 ℃ and 15 ℃ did not reveal the optimal consumption time; however, fresh pork stored at 10 ℃ and 4 ℃ revealed the optimal consumption time after storage for 36 hours and 48－72 hours, respectively. Fresh pork stored at 25, 20, 15, 10 ℃ and 4 ℃ could maintain the optimal consumption time within 12, 18, 36, 48 hours and 96 hours. Within 48 hours, fresh pork stored at 10 ℃ had no significant difference in cooking lose, color (L* value and a* value) and TVB-N, but had better shear force when compared with the fresh pork stored at 4 ℃.
