Premature browning (PMB) describes cooked beef that may appear done before reaching 71°C. Ground beef from paired Longissimus lumborum (LL) and Psoas major (PM) muscles was formed into patties. Patties were cooked immediately, and after 48 and 96 h storage at 4°C. Total reducing activity (TRA) and external color were measured immediately prior to cooking. Patties were cooked to internal end point temperatures of 60,66,71 or 77°C and internal cooked color (L*, a* and b* values) was measured. Raw PM patties had greater L* values and lesser a* values than those from LL (P < 0.05). For LL and PM, raw a* and b* values decreased with storage from 0 h to 96 h (P < 0.05). At 0 and 48 h storage, cooked patties prepared from PM had greater a* values than those prepared from LL at all internal endpoint temperatures (P < 0.05). Internal cooked a* values of patties from PM decreased with storage of raw patties, whereas it was stable for LL patties (P < 0.05).
