Shelf-life and Microbiological Profiler of Chicken Wing Products Following Sous vide Treatment

Abstract

Chicken wings were vacuum-packaged and cooked (sous vide) at 75 and 90 C until the internal o temperature reached 73.8 C was reached. The cooked samples were stored at 2 and 7 C, separately. The o o TBA values, aerobic plate count, aerobic and anaerobic plate counts and Warner-Bratzler (WB) shear force of the samples were evaluated weekly for 7 wk. The sous vide treatment chicken wings had lower TBA values, aerobic and anaerobic plate counts throughout the 7 wk of storage when compared with the control. The sous vide treatment did not affect the WB shear force of chicken wings. At 2 C, the sous vide cooked o chicken wings had a shelf life of at least 7 wk. Results demonstrate that sous vide treatment was an effective method to prevent lipid oxidation during storage and enhance shelf life of chicken wing products.
