Effect of Sodium Nitrite Concentration, Sodium Erythorbate and Storage Time on the Quality of Franks Manufactured from Mechanically Deboned Turkey

摘要

ABSTRACTThe effects of sodium nitrite (0‐156 ppm), sodium erythorbate (0 or 550 ppm) and storage time (up to 10 wk at 4°C) were measured on the chemical and sensory properties of turkey franks formulated largely from mechanically deboned turkey (MDT), Residual nitrite in the finished product was proportional to that incorporated at time of formulation and was reduced by using small initial amounts in combination with the maximum allowable erythorbate (550 ppm). Acceptable cured color in turkey franks was achieved with the incorporation of 50 ppm of nitrite. Erythorbate effectively increased cured color development and stability, particularly with smaller amounts of nitrite. Rancidity development in turkey franks was not of major significance. Even so, the presence of erythorbate imposed further control of oxidative changes in lipids. Maximum cured flavor development occurred with 50–100 ppm nit
