ABSTRACT

Understanding the factors affecting meat eating quality and consumer demand is essential for estimating future trends in meat consumption. The objective of the study was therefore to compare Czech and Spanish consumer attitudes and preferences in relation to beef intramuscular fat content. Three hundred and one consumers participated in the study; they completed a sociodemographic questionnaire and evaluated grilled beef samples of three varying intramuscular fat contents (low, medium, high). The low-fat meat had an average intramuscular fat content of 1.3%, medium had 3.1% and high-fat had 5.2%. Sensory assessment scores tended to show a positive linear relationship with beef intramuscular fat content. While Czech assessors only noted differences in tenderness and overall acceptance between the beef samples, Spanish assessors were able to detect significant differences in all the descriptors evaluated. Age and gender affected the assessment scores of beef with different intramuscular fat contents.

ABSTRACT

The histochemical characteristics, physical attributes, chemical composition, and sensory profile of three muscles (longissimus thoracis et lumborum - LTL, rectus abdominis - RA, triceps brachii - TB) from Fleckvieh (N = 24) bulls and heifers were compared. Samples of each muscle were taken within 1 h of slaughter to assess muscle fibre traits, while physio-chemical meat quality was assessed in each muscle at 48 h post mortem, followed by the sensory assessment of the muscles after 7 days of ageing. Despite identical raising conditions, bulls showed more favourable growth and slaughter performance, but heifers produced meat with more favourable sensory characteristics, as a result of a higher proportion of IIB fibres in their muscles, as well as a higher intramuscular fat content, and lower collagen content.
