Effects of combined wet- and dry-aging techniques on the physicochemical and sensory attributes of beef ribeye steaks from grain-fed crossbred Zebu steers

摘要

The effects of dry- and wet-aging combinations on the sensory and physicochemical attributes of beef ribeye steaks were investigated. Paired beef ribs ( n ?=?16) from eight grain-fed crossbred Zebu steers ( n ?=?16) were divided into unaged, 28?d wet, 28?d dry, 14?d wet?+?14?d dry, and 14?d dry?+?14?d wet. Aging was conducted in a chamber at 2?°C with 73% relative humidity and without airflow. Dry-aged and combined-aged products had greater percentages of total loss compared with wet-aged products during the aging and fabrication, resulting in lower total saleable product ( P ??0.05). In addition, all aged samples presented higher proportion of tender steaks (87%; P ??0.05). The combination of both aging techniques did not offer any advantage, and the wet-aging process alone appears to be the most efficient strategy for the Brazilian food service to maximize palatability characteristics of beef.
