title: Functionality of cow beef in coarse and fine ground model systems.
abstract: Patties and sausage batters were made from trimmed brisket, chuck, striploin, hindshank, silverside, thick flank and rib trim from grass-fed Friesian cows. Functionality of each meat cut was determined from cook yield and true stress and strain of cooked sausage batters and cook yield, dimensional changes and peak force of cooked patties. Colour of raw and cooked slices from the meat cuts and cooked batters was evaluated using a colorimeter and a consumer panel. Composition of raw meat from all cuts was similar; chuck and rib trim had higher pH values and were more red than meat from other cuts. Cooked batters from striploin, chuck and hindshank had higher stress and strain values than gels from other cuts. Patties made from thick flank and striploin were the softest and had the highest cook yield. Batters and patties made from meat with higher salt soluble protein content retained more water and fat on cooking, were more cohesive and had higher bind strengths. Manufacturers can use functionality characteristics to select meat for specific products.
