چکیده
The objectives of this study were to determine the influence quality grade and internal temperature on thermophysical properties beef strip steaks. Beef loins (n=24) collected from USDA Prime (PR), Low Choice(LC), Standard (ST) carcasses. Strip fabricated into 2.54 cm steaks at 21 d postmortem randomly assigned an (4°C, 25°C, 55°C, 60°C, 71°C, 77°C). Steaks subjected various thermal physical property measurements. No × interaction was observed for diffusivity conductivity (P > 0.05). tempered 25°C had greatest compared with all other treatments = 0.021).

Does Knowing Brand or USDA Grade of Beef Strip Steaks Affect Palatability for Consumers?
In consumers’ eyes, not all beef is considered equal. In addition to USDA quality grades, close to 150 branded beef programs are approved for the segregation and marketing of beef products (USDA, 2015). This large number of product categories allows consumers to have a choice in the products they purchase. Blind sensory panel testing of beef, where consumers are not shown the brand or informati...

A consumer study was conducted to determine palatability ratings of beef tenderloin steaks from USDA Choice, USDA Select, and USDA Select with marbling scores from Slight 50 to 100 (USDA High Select) cooked to various degrees of doneness. Steaks were randomly assigned to 1 of 3 degree of doneness categories: very-rare, medium-rare, or well-done. Consumers (N = 315) were screened for preference ...
