Beef patty composition: effects of fat content and cooking method

Patties from ground round, ground chuck , and regular ground beef containing 14%, 19%, and 24% fat, respectively, were cooked by six different methods and analyzed for compositional differences. Cooking methods were electric broiling , charbroiling , roasting, convection heating, frying, and microwave heating. Percent yield, fat, and moisture of cooked patties were significantly affected (p less than .05) by the interaction of fat level and cooking method. Except for patties cooked by broiling or convection heating, patty yields decreased with increasing fat levels. Leaner formulations of ground beef increased in fat percentage with cooking, while patties processed to contain more fat initially decreased in fat percentage following cooking. Microwave cooking always produced patties containing the least fat and caloric content in comparison with other methods. Increasing levels of fat in the raw patty formulation did not appear to affect substantially the total caloric value of the patties following cooking. Cooked patties processed to have 14% fat contained slightly more water and less fat than patties having 24% fat. At current retail prices, cooked patties made to have 14% fat cost +0.20 more per patty than patties produced to contain 24% fat, regardless of the method of cooking.
