This study was conducted to evaluate the effect of storage temperature and duration on oxidation and flavour changes in frozen pork dumpling filler. Freshly prepared dumplings were stored for 0, 30, 60, 90, and 180 d at -7°C, -18°C, and an oscillation between -7°C and -18°C. The samples stored at -7°C for 180 d had significantly higher levels of TBARS and protein carbonyls than those stored at -18°C and the fluctuating -7°C/-18°C (P
