Beef strip loins from either the right or left side of 22 carcasses of Bos indicus-type steers were injected with 200 mM calcium chloride (CaCl2) solution at 5% (wt/wt) to determine its effect on tenderness and other selected quality traits of steaks. Loins from opposite sides of the carcasses were untreated and served as the control. The steaks were evaluated for tenderness, juiciness, flavor intensity, tenderness acceptability, and overall acceptability by 62 restaurant consumers over a 6-wk period. The CaCl2 injection improved (P < .05) tenderness and flavor intensity ratings by the restaurant consumers. Tenderness acceptability and overall acceptability were improved 23 and 17%, respectively, by the CaCl2 injection. Flavor was not compromised by the CaCl2 injection. The CaCl2-treated steaks were rated superior(P < .05) for flavor compared to the control steaks. Restaurant consumers preferred the beef loin strip steaks injected with 200 mM CaCl2 at 5% (wt/wt). The results of this study are interpreted to indicate that, from a restaurant consumer perspective, CaCl2 injection is an acceptable means of making beef a more consistently tender product.
选取22头印度瘤牛型阉牛的左右侧牛柳,注射5%(重量/重量)的200 mM氯化钙(CaCl2)溶液,以确定其对牛排嫩度和其他选定品质特性的影响。牛躯体另一侧的牛柳不做处理,作为对照。在6周时间内,62名餐厅消费者对牛排的嫩度、多汁性、风味强度、嫩度可接受性和总体可接受性进行了评估。氯化钙注射提高了(P < .05)餐厅消费者对嫩度和风味强度的评分。氯化钙注射使嫩度可接受性和总体可接受性分别提高了23%和17%。氯化钙注射并未影响风味。与对照牛排相比,经氯化钙处理的牛排风味更佳(P < .05)。餐厅消费者更喜欢注射了5%(重量/重量)的200 mM氯化钙的牛柳牛排。该研究结果表明,从餐厅消费者的角度来看,氯化钙注射是使牛肉更均匀嫩化的一种可接受方法。
