We hypothesized that unique ground beef products could be formulated from brisket, flank, and plate primals. Primals were taken from 4 USDA Select carcasses from conventionally produced cattle, selected at random in a commercial packing plant. Lean and fat trims were separated, and ground beef was formulated from each primal to contain 10, 20, or 30% total fat. Brisket patties contained higher proportions of monounsaturated fatty acids and less saturated fatty acids than flank patties. There were no differences in n-6 or n-3 fatty acids across primal type or fat level. After cooking, brisket patties had higher bloody/serumy and fat-like descriptor values than flank patties. Plate patties generated higher amounts of lipid-derived volatiles than patties from the brisket or flank. Brisket patties generally had higher amounts of pleasant headspace volatiles whereas the plate relied more heavily on Maillard-derived volatiles than flank patties. We conclude that individual primals can be used to formulate ground beef with unique compositional and flavor characteristics.
我们假设可以用牛腩、腹肉排和胸骨肉等独特的牛肉部位来制作不同的绞碎牛肉产品。这些原料取自于 4 个美国农业部选择级别的牛的躯体,在商业屠宰场随机挑选。将瘦肉和脂肪部分分开,然后用每个部位的原料来制作总脂肪含量分别为 10%、20%或 30%的绞碎牛肉。与腹肉排相比,牛腩饼含有更高比例的单不饱和脂肪酸和更少的饱和脂肪酸。在不同的原料类型和脂肪含量水平下,n-6 或 n-3 脂肪酸没有差异。烹饪后,牛腩饼的血腥/血清和脂肪味描述值比腹肉排高。与来自牛腩或腹肉的肉饼相比,胸骨肉饼产生了更多的脂质衍生挥发物。牛腩饼通常含有更多令人愉悦的顶空挥发物,而胸肉则比腹肉排更多地依赖美拉德衍生挥发物。我们得出结论,单个的原料可以用来制作具有独特成分和风味特征的绞碎牛肉。
