Boneless chucks from chilled mature bull and hot boned and chilled USDA Cutter‐Canner cow carcasses were processed into patties after fat was adjusted and meat comminuted either by grinding or mechanical desinewing (0.19 cm, 0.25 cm, 0.19‐0.25 cm double aperture, 0.25‐0.32 cm double aperture heads). In comparison with grinding, use of smaller aperture sizes in desinewing reduced total collagen and increased tenderness ratings only of patties made from chilled cow beef. For mature bull and hot boned cow beef, grinding produced higher palatability values than desinewing. Tenderness ratings and shear values were not closely related to total collagen when desinewing was used on mature bull and hot boned cow beef. Palatability advantages in favor of hot boned over cold boned beef were found primarily when beef was ground rather than desinewed. Levels of moisture in cooked patties were high when single aperture heads were used for hot boned cow beef and intermediate size heads (0.19–0.25 cm) were used for cold boned cow beef.
