Enhancing and understanding the tenderness of beef has been an on-going research topic. Recently, injection of compounds into fresh beef muscle is an active area of research. In this preliminary study, four cows of E maturity were the source of eight strip loins. The steaks from the strip loins were split into treatment groups and injected at 24 hours postmortem to a 10% level (v/w) with one of...

Fifty-six retail stores representing 15 retail chains and 14 foodservice facilities in eight U.S. cities were sampled to determine the tenderness of beef steaks at retail and foodservice levels based on Warner-Bratzler shear (WBS) values and consumer evaluation panels. Retail consumer panels were conducted at five universities. Each retail and foodservice steak was evaluated using 10-point scal...

Two experiments were conducted to determine the effectiveness of using mechanical probes and objective color measurement on beef LM to predict cooked tenderness. In Exp. 1, sharp needle (SN), sharp blade (SB), blunt needle (BN), blunt blade (BB), and plumb bob (PB) probes were used to measure uncooked LM (n = 29) at 2 d postmortem in both a perpendicular and parallel orientation to the long axi...

Consumers today consider tenderness to be the single most important determinant of beef quality. This is reflected by the positive relationship between retail price of a beef cut and its perceived tenderness (i.e., tenderloin steak). The most recent National Beef Quality Audit estimated that the inconsistencies associated with beef tenderness potentially cost the U.S. beef industry approximatel...

The current experiment was conducted to evaluate the on-line application of visible and near-infrared spectroscopy (VISNIR) to US Select carcasses during commercial beef carcass grading procedures to predict tenderness of longissimus steaks after 14 days of refrigerated storage. A regression model was calibrated using 146 carcasses and tested against an additional 146 carcasses. Carcasses were ...

Data were tenderness measures on steaks from 237 bulls (Group II) slaughtered after producing freezable semen and on 1,431 related steers and heifers (market animals, Group I) from Angus, Hereford, Pinzgauer, Brahman, and Sahiwal crosses from the Germ Plasm Evaluation project at the U.S. Meat Animal Research Center. Tenderness was assessed through Warner-Bratzler Shear Force (SF), taste panel t...

BACKGROUND We wished to determine if there were differences in pelvic and non-pelvic tenderness between men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) Type III and men without pelvic pain. METHODS We performed the Manual Tender Point Survey (MTPS) as described by the American College of Rheumatology on 62 men with CP/CPPS Type IIIA and IIIB and 98 men without pelvic pain....

The tenderness characteristics of 15 primal cuts of beef of three different age groups were assessed, and the most reliable cut to predict carcass tenderness was determined. Fifteen wholesale cuts from each age group, representing the full variation in fatness, were aged, cooked and underwent sensory evaluation, shear force resistance and proximate analysis. Collagen content and solubility was ...

background: women's role in family and their participation in social, economical and cultural activities make them a part of development process. paying attention to women's health is a social investment. nowadays 70% of women suffer from breast pain and two third of these pains are periodical. among the pain killing methods, herbal medicine is more compatible with human body and has fewer side...

the objective of the present study was to determine if modifications would occur due to epinephrine perfusion and simulating stressful situations (2 µg/ kg/ min, an animal)and transportation,causing change of the values of extractable protein concentrations, sds page profiles and the calpain calpastatin complex in silver rabbit longissimus muscles resulting in consequent changes in meat tendern...
