To determine US consumer acceptance and value of beef from various countries, 24 taste panels of consumers (n = 273 consumers) were conducted in Denver and Chicago. Two pairs of strip steaks were evaluated for flavor, juiciness, tenderness, and overall acceptability on eight-point hedonic scales. One pair consisted of an Australian grass-fed strip steak and a domestic strip steak, whereas the other pair included Canadian and domestic strip steaks. The pairs were matched to similar Warner-Bratzler shear values and marbling scores to decrease variation associated with tenderness and juiciness. A variation of the Vickery auction was used to obtain silent, sealed bids on steaks (0.45 kg) from the same strip loins sampled in the taste panel. Consumers gave higher (P < 0.001) scores for flavor, juiciness, tenderness, and overall acceptability for domestic steaks compared with Australian grass-fed steaks. Domestic steaks averaged 3.68/0.45 dollars kg, whereas consumers placed an average value of 2.48/0.45 dollars kg on Australian grass-fed steaks (P < 0.001). Consumers rated Canadian steaks numerically lower for juiciness (P = 0.09) and lower (P < 0.005) for flavor, tenderness, and overall acceptability than domestic samples. Consumers placed an average value of 3.95/0.45 dollars kg for domestic steaks and 3.57/0.45 dollars kg for Canadian steaks (P < 0.01). Consumers (19.0%) who preferred Australian grass-fed steaks over domestic steaks paid 1.38/0.45 dollars kg more (P < 0.001), whereas consumers (29.3%) who favored the Canadian steaks over the domestic steaks paid 1.37/0.45 dollars kg more (P < 0.001) for the Canadian steaks. A majority of US consumers seem to be accustomed to the taste of domestic beef and prefer domestic steaks to beef from Australia grass-fed and Canadian beef.
为了确定美国消费者对来自不同国家牛肉的接受程度和价值,在丹佛和芝加哥对24个消费者品尝小组(n = 273名消费者)进行了调查。使用八点享乐量表对两对里脊牛排的风味、多汁性、嫩度和总体可接受性进行了评估。其中一对包括一块澳大利亚草饲里脊牛排和一块国产里脊牛排,而另一对包括一块加拿大里脊牛排和一块国产里脊牛排。将这两对牛排的沃纳-布拉茨勒剪切值和大理石花纹评分匹配至相似水平,以减少与嫩度和多汁性相关的差异。采用维克里拍卖的一种变体形式,对品尝小组中所取相同里脊腰肉部位的牛排(0.45千克)进行无声密封投标。与澳大利亚草饲牛排相比,消费者对国产牛排的风味、多汁性、嫩度和总体可接受性给出了更高的分数(P < 0.001)。国产牛排平均价格为3.68美元/0.45千克,而消费者对澳大利亚草饲牛排的平均估价为2.48美元/0.45千克(P < 0.001)。消费者对加拿大牛排多汁性的评分在数值上低于国产牛排(P = 0.09),在风味、嫩度和总体可接受性方面的评分也低于国产牛排(P < 0.005)。消费者对国产牛排的平均估价为3.95美元/0.45千克,对加拿大牛排的平均估价为3.57美元/0.45千克(P < 0.01)。比起国产牛排更喜欢澳大利亚草饲牛排的消费者(19.0%),为澳大利亚草饲牛排多支付了1.38美元/0.45千克(P < 0.001),而比起国产牛排更喜欢加拿大牛排的消费者(29.3%),为加拿大牛排多支付了1.37美元/0.45千克(P < 0.001)。大多数美国消费者似乎习惯了国产牛肉的味道,比起澳大利亚草饲牛肉和加拿大牛肉,更喜欢国产牛排。
