The effects of whole egg powder (WEP), dried albumen (DA), dried yolk (DY) at a 1% level and liquid egg (LE) at a 3.7% level on the quality characteristics and refrigerated storage (4 ± 1 °C) stability of chicken patties made with meat and by-products of broiler-spent hens were evaluated. The addition of egg powders significantly enhanced the emulsion stability (ES) and product yield compared with control and LE. There was a marked increase in moisture content and sensory attributes by the addition of egg powders. During the refrigerated storage (4 ± 1 °C), thio-barbituric acid number (TBARS), aerobic plate count (APC) and psychrophilic count increased in all samples. Incorporation of DA and DY significantly reduced the TBARS number and APC during the storage over control. The addition of DA, DY and WEP significantly lowered the psychrophilic counts. Treated and control patties packaged in LDPE (low-density polyethylene) pouches were acceptable for 20 days and 15 days, respectively.
