Abstract

With the recent development of technology to classify beef for tenderness, it is now possible for packers and retailers to market brands of beef known to be consistently tender. The present experiment was conducted to determine consumer impressions of Tender Select, a model beef brand comprised of cuts from tender U.S. Select carcasses. A telephone survey was conducted in metropolitan Denver, CO, to recruit consumers (n = 1,036) for this study. Consumers who met minimal limits for household income, age, and beef consumption were invited to participate in a beef shopping and usage study in a local supermarket. Point-of-purchase material was developed that described Tender Select as "the only steak guaranteed tender and lean." When shown a copy of the Tender Select concept card, 89% of participating consumers (n = 759) indicated that they would definitely or probably buy that product. Of those consumers that said they would buy the product, 35% indicated that their purchases of Tender Select would be in addition to their current fresh meat purchases. Most consumers (54.1%) indicated that if Tender Select was available at their grocery store, 1 or 2 of their next 10 purchases of beef cuts would be Tender Select. Sixty-five percent of consumers indicated that if a grocery store carried a line of beef cuts guaranteed to be tender, they would buy all of their beef at that store. Both strip loins from 104 U.S. Select beef carcasses, representing a broad range (8.7 to 43.4 kg; CV = 42%) in slice shear force (SSF) at 14 d postmortem, were used to determine the effect of SSF classification on consumer satisfaction and the correlation among trained sensory panel descriptive attribute ratings and in-home consumer ratings of beef longissimus steaks. Both trained sensory panelists and consumers rated low-SSF steaks higher than the high-SSF steaks for all traits (P < 0.001). All consumer traits (like, tenderness, juiciness, flavor like, flavor amount, and overall satisfaction) were more highly correlated with SSF and trained sensory panel tenderness ratings than with sensory panel flavor or juiciness ratings. These data show that tenderness is the primary determinant of satisfaction among consumers of U.S. Select top loin steaks and that a segment of consumers would pay a premium to purchase guaranteed-tender U.S. Select steaks.

摘要

随着近期牛肉嫩度分级技术的发展,如今包装商和零售商能够销售已知始终保持嫩度的牛肉品牌。本实验旨在确定消费者对“精选嫩肉”(Tender Select)的印象,这是一个由美国精选级嫩牛胴体切割而成的牛肉品牌。在科罗拉多州丹佛市进行了一项电话调查,招募消费者(n = 1036)参与本研究。符合家庭收入、年龄和牛肉消费量最低限制的消费者被邀请参加当地一家超市的牛肉购买及使用研究。开发了购买点宣传材料,将“精选嫩肉”描述为“唯一保证嫩且瘦的牛排”。当向参与的消费者(n = 759)展示“精选嫩肉”概念卡副本时,89%的消费者表示他们肯定或可能会购买该产品。在表示会购买该产品的消费者中,35%表示购买“精选嫩肉”将是在他们当前鲜肉购买量之外。大多数消费者(54.1%)表示,如果杂货店有“精选嫩肉”,他们未来10次购买牛肉切块中有1至2次会选择“精选嫩肉”。65%的消费者表示,如果杂货店有一系列保证嫩的牛肉切块,他们会在该店购买所有牛肉。使用来自104头美国精选级牛胴体的里脊,这些牛胴体在宰后14天的切片剪切力(SSF)范围广泛(8.7至43.4千克;变异系数=42%),以确定SSF分级对消费者满意度的影响,以及训练有素的感官评定小组描述性属性评分与家庭消费者对牛肉背最长肌牛排评分之间的相关性。对于所有特征,训练有素的感官评定小组成员和消费者对低SSF牛排的评分均高于高SSF牛排(P < 0.001)。与感官评定小组的风味或多汁性评分相比,所有消费者特征(喜欢程度、嫩度、多汁性、风味喜欢程度、风味量和总体满意度)与SSF以及训练有素的感官评定小组嫩度评分的相关性更高。这些数据表明,嫩度是美国精选级上腰部牛排消费者满意度的主要决定因素,并且一部分消费者愿意支付溢价购买保证嫩的美国精选级牛排。
