Hospital cook/chill foodservices systems. Effect of end temperature of initial cooking on yield and moisture of beef loaf during processing.
Hospital cook/chill foodservice systems are characterized by two heat processes: Intial cooking and microwave heating for service. End temperature (ET) of initial cooking for beef loaf in actual and in simulated cook/chill systems has been reported to vary from 123 degrees F. (51 degrees C.) to 170 degrees F. (77 degrees C.). After preparation, beef loaf (5 kg.) was initially uncooked or initially cooked to ETs of 113 degrees, 140 degrees, 167 degrees, or 194 degrees F. (45 degrees, 60 degrees, 75 degrees, or 90 degrees C.), stored chilled (24 hr. at 42 degrees F. [6 degrees C]), and portions (100 gm.) were microwave heated to 165 degrees F. (74 degrees C.) or above. Multiple comparison t-test on data for yield and for moisture content of beef loaf indicated that increasing the ET of initial cooking significantly (P of less than or equal to 0.01) decreased yield and moisture content of beef loaf after initial cooking and after microwave heating for service.
