Carcass chilling method and electrical stimulation effects on meat quality and color in lamb.

Five treatments: Control (C), Pre-evisceration Electrical Stimulation (CES: 15 Hz, 700 mA, 500 μs pulse width, 45 s pulse duration), vascular Rinse & Chill® (RC), CES + RC (ESRC), and RC with ES after evisceration (RCES:15 Hz, 600 mA, 1000 μs, 45 s), were applied to 21 lambs each. After being excised from the carcass, muscles were vacuum packaged and aged (Longissimus lumborum, LL, 3 and 22 d postmortem; Semimembranosus, SM, 3 d postmortem). Temperature, pH, purge, cooking loss, color, Warner-Bratzler Shear Force (WBSF), and consumer sensory evaluations were determined.

Canola meal as a supplement for grass-fed beef cattle: Effects on growth rates, carcase and meat quality, and consumer sensory evaluations.

The current study examined the growth rates, carcase characteristics, meat quality, and consumer sensory evaluation of the longissimus lumborum muscle (striploin) from steers that were supplemented with either canola meal or grain-based pellets. Forty Angus and Hereford × Angus steers received one of these two supplements with ad libitum lucerne hay for 60 d prior to slaughter. Average daily weight gain was not affected by dietary treatment; however, hot standard carcase weight was significantly lower for steers offered canola meal compared with steers on the grain-based pellets.

A comparison of Japanese and Australian consumers' sensory perceptions of beef.

This paper presents a comparison of Japanese and Australian consumer sensory responses to beef, based on Meat Standards Australia methodology. Japanese and Australian consumers evaluated paired beef samples according to four sensory traits, and the weighted results were combined to produce a Meat Quality score (MQ4). The consumers also categorized the beef samples to one of four grades (unsatisfactory, good everyday, better than everyday and premium).

Japanese consumer categorisation of beef into quality grades, based on Meat Standards Australia methodology.

The objective was to evaluate the sensory categorisation of beef by Japanese consumers, based on Meat Standards Australia methodology. Various cuts of beef, with a wide range of quality (from Australian and Japanese cattle) and three cooking methods (grill, yakiniku, shabu shabu), were evaluated by 1620 Japanese consumers in Tokyo and Osaka. Consumers rated each sample for four sensory attributes (tenderness, juiciness, flavor and overall satisfaction), then selected one of four grades (unsatisfactory/2-star, good everyday/3-star, better than everyday/4-star, and premium quality/5-star), based on the quality of the beef within each cooking method.
