Tenderness, juiciness, and flavor have been associated with consumer acceptance of beef, lamb, and pork. Drivers of consumer liking are interrelated across these species, but there are differences in consumer preferences. Animal age, animal diet, and subsequent marbling impact consumer liking across species. For beef, consumer research prior to the 1990s showed that tenderness was the main driver of liking. Consumer tenderness and juiciness liking are highly correlated. More recent research has shown that as overall tenderness improved and tenderness variation decreased, flavor has become a more important driver of beef consumer liking. Flavor is affected by consumer preparation methods, familiarity with different flavor presentations, and animal production systems. Animal diet impacts consumer perception of beef tenderness and flavor, especially when comparing forage-fed versus grain-fed beef. Flavor preferences vary across countries more so than preferences for beef based on consumer tenderness preferences and are most likely influenced by the consumption of locally produced beef and the flavor-derived type of beef traditionally consumed. Drivers of pork consumer liking have been shown to be affected by pH, color, water holding capacity, animal diet, and the presence of boar taint compounds. While tenderness and juiciness continue to be drivers of consumer liking for pork, flavor, as impacted by animal diet and the presence of boar taint compounds, continues to be a driver for consumer liking. For lamb, the flavor, as affected by diet, and animal age continue to be the main drivers of consumer liking. Lamb consumers vary across countries based on the level of consumption and preferences for flavor based on cultural effects and production practices.

Drivers of Consumer Liking for Beef, Pork, and Lamb: A Review.

Modelling of beef sensory quality for a better prediction of palatability

An experiment was set up for (i) comparing Australian and French consumer preferences to beef and to (ii) quantify how well the Meat Standards Australia (MSA) grading model could predict the eating quality of beef in France. Six muscles from 18 Australian and 18 French cattle were tested as paired samples. In France, steaks were grilled 'medium' or 'rare', whereas in Australia 'medium' cooking was used. In total, 360 French consumers took part in the 'medium' cooking test, with each eating half Australian beef and half French beef and 180 French consumers tested the 'rare' beef. Consumers scored steaks for tenderness (tn), juiciness (ju), flavour liking (fl) and overall liking (ov). They also assigned a quality rating to each sample: 'unsatisfactory', 'satisfactory everyday quality' (3*), 'better than everyday quality' (4*) or 'premium quality' (5*). The prediction of the final ratings (3*, 4*, 5*) by the French consumers using the MSA-weighted eating quality score (0.3 tn + 0.1 ju + 0.3 fl + 0.3 ov) was over 70%, which is at least similar to the Australian experience. The boundaries between 'unsatisfactory', 3*, 4* and 5* were found to be ca. 38, 61 and 80, respectively. The differences between extreme classes are therefore slightly more important in France than in Australia. On average, even though it does not have predictive equations for bull meat, the mean predicted scores calculated by the MSA model deviated from observed values by a maximum of 5 points on a 0 to 100 scale except for the Australian oyster blade and the French topside, rump and outside (deviating by <15). Overall, the data indicate that it would be possible to manage a grading system in France as there is high agreement and consistency across consumers. The 'rare' and 'medium' results are also very similar, indicating that a common set of weightings and cut-offs can be employed.

Prediction of beef eating quality in France using the Meat Standards Australia system

The Meat Standards Australia (MSA) grading scheme has the ability to predict beef eating quality for each ‘cut×cooking method combination’ from animal and carcass traits such as sex, age, breed, marbling, hot carcass weight and fatness, ageing time, etc. Following MSA testing protocols, a total of 22 different muscles, cooked by four different cooking methods and to three different degrees of doneness, were tasted by over 19 000 consumers from Northern Ireland, Poland, Ireland, France and Australia. Consumers scored the sensory characteristics (tenderness, flavor liking, juiciness and overall liking) and then allocated samples to one of four quality grades: unsatisfactory, good-every-day, better-than-every-day and premium. We observed that 26% of the beef was unsatisfactory. As previously reported, 68% of samples were allocated to the correct quality grades using the MSA grading scheme. Furthermore, only 7% of the beef unsatisfactory to consumers was misclassified as acceptable. Overall, we concluded that an MSA-like grading scheme could be used to predict beef eating quality and hence underpin commercial brands or labels in a number of European countries, and possibly the whole of Europe. In addition, such an eating quality guarantee system may allow the implementation of an MSA genetic index to improve eating quality through genetics as well as through management. Finally, such an eating quality guarantee system is likely to generate economic benefits to be shared along the beef supply chain from farmers to retailors, as consumers are willing to pay more for a better quality product.

Review: The variability of the eating quality of beef can be reduced by predicting consumer satisfaction.

Of the 345 million people in the Southern African Development Community (SADC), 30.6% are severely food insecure, 8% malnourished and 50% live with less than US $1 per day, respectively. Livelihood, food and nutrition security have, therefore, become key priorities for the SADC region in response to these complex challenges. Given that 70% of the SADC population directly rely on agriculture for food, nutrition and income, sustained agricultural productivity may play an important role in achieving livelihood, food and nutrition security in the region. Being an important part of the agri-food system of marginalised communities in the region, cattle have great potential to contribute to the goal of reducing food and nutrition insecurity. The region has a population size of about 64 million cattle of which 75% of the population is kept under the smallholder farming systems, and primarily composed of indigenous tropical breeds. Most indigenous cattle breeds are, however, either undergoing rapid genetic dilution or at risk of extinction. At the same time, their environments, production and marketing systems are experiencing high rates of change in time and space. More importantly, indigenous cattle breeds in the region are undervalued. This makes it uncertain that future systems will have the adapted cattle breeds required for optimal livelihoods, food and nutrition security. To this end, the promotion of sustainable use of indigenous cattle for livelihood, food and nutrition security in the SADC region is strongly recommended.
