On the other hand, addition of WFC continually decreased MbFe2+O2 and MbFe2+ but increased MbFe3+ contents of meat batters with 120 ppm nitrite. At an added level of 2% WFC, meat batters without nitrite showed higher MbFe2+ (P < 0.05) and MbFe2+O2 (P < 0.001) but lower MbFe3+ (P < 0.001) contents than that with only 120 ppm nitrite.
