Attitudes toward artificial meat in Arab countries.

In development for almost 20 years, artificial meat (also known as "cell-based meat," "cell-cultured meat," "cultured meat," "cultivated meat," "in vitro meat" and "lab-grown meat") is the most striking example of cellular agriculture. This research aims to study Arab consumers' attitudes toward artificial meat, which is a topic of great interest to scientists and the media. An online survey was conducted with 1025 participants revealed that 17% consider artificial meat to be promising and acceptable.

Does transport affect the eating quality potential of beef from Limousin cows in France? - A case study.

We hypothesized that transportation might impact beef sensory quality, particularly as the distance between farms and the slaughterhouse increases. Specifically, we expected that pre-slaughter transport over longer distances would induce stress in the cattle, resulting in elevated ultimate pH and, consequently, reduced beef quality. Thus, this study aimed to specifically study the effects of transport in commercial conditions of Limousin cows from farms located in different areas of France to slaughter on ultimate pH (pHu) measured in the muscle (LT), marbling (two major factors affecting eating quality) and the MSA Index (a global indicator of potential eating quality at the carcass level).

German consumers' attitudes toward artificial meat.

The aim of this study was to analyze the impact of sociodemographic characteristics on willingness to try (WTT), regularly eat (WTE), or pay (WTP) for artificial meat, its expected societal challenges and general acceptance as well as its future potential development in Germany. Answers to an online questionnaire by 3,558 potential German adult consumers were evaluated. About 63% of the respondents thought this novel food was promising/acceptable.

Discrimination of beef composition and sensory quality by using rapid Evaporative Ionisation Mass Spectrometry (REIMS).

Herein, we investigated the potential of REIMS analysis for classifying muscle composition and meat sensory quality. The study utilized 116 samples from 29 crossbred Angus × Salers, across three muscle types. Prediction models were developed combining REIMS fingerprints and meat quality metrics.

Does transport stress have any effect on carcass quality of Nellore cattle () in Brazil? - A case study.

With the increasing concomitant demands for Brazilian beef and in particular high-quality beef, there is a need for observational studies of the effects of pre- and post-slaughter practices on beef carcass traits. We hypothesized in our case study that pre-slaughter transport of bovines over significant distances would induce stress in animals, and that this would reduce carcass quality because of higher pH resulting from long-distance transportation. To test this hypothesis, 30,230 Nellore carcasses from a private slaughterhouse were evaluated 24 h .

Perception of cultured "meat" by Italian, Portuguese and Spanish consumers.

The aim of this study was to investigate how consumers ( = 2,171) originated from South-Western Europe (Italy, Portugal, and Spain) perceive cultured "meat" (CM) and if their demographic characteristics (origin, gender, age, education, occupation, and meat consumption) are related to their willingness to try (WTT), to regularly eat (WTE) and to pay (WTP) for CM. We found the current respondents had an initially positive attitude towards CM: 49% of them perceived CM as "promising and/or acceptable" and 23% "fun and/or intriguing" whereas 29% considered it as "absurd and/or disgusting". In addition, 66 and 25% would be willing and not willing to try CM, respectively.

Consumer perception of "artificial meat" in the educated young and urban population of Africa.

African's population is expected to grow especially in cities to reach about 2.5 billion in 2050. This will create an unprecedented boom in the demand for animal products over the coming years which will need to be managed properly.

Consumer perception of the challenges facing livestock production and meat consumption.

With the global meat market growing and intensive livestock farming systems increasing, the impacts of livestock are a growing concern among consumers, further influencing their meat consumption. Understanding consumer perceptions of livestock production is therefore a key issue. This study surveyed 16,803 respondents in France, Brazil, China, Cameroon and South Africa to investigate the different perceptions of the ethical and environmental impacts of livestock production among consumer segments in different countries based on their sociodemographic characteristics.

French consumer evaluation of eating quality of Angus x Salers beef: Effects of muscle cut, muscle slicing and ageing.

Based on the Meat Standards Australia (MSA) methodology, the objectives of this study were to evaluate the eating quality of grass-fed Angus x Salers beef by French consumers, across different muscle cuts (m. triceps brachii caput longum, m. longissimus dorsi et thoracis and m.

Carcass Characteristics and Beef Quality of Young Grass-Fed Angus x Salers Bovines.

To characterize carcass and meat attributes, such as beef eating quality in specific farming conditions, 31 young grass-fed crossbred Angus x Salers cattle in two farming systems (a mono-cattle system versus a mixed system with beef cattle and sheep) were used in this study. Three muscle cuts (striploin-; bolar blade-; internal flank plate-) were used for consumer eating quality testing and striploin was used for panelist eating quality assessment, and objective measurements [Warner-Bratzler shear force (WBSF) and fatty acid (FA) and antioxidant contents]. Results indicated that the farming system had no impact on carcass characteristics or meat quality, but it tended to affect FA content, which is likely explained by between-system differences in animal maturity (assessed by ossification score).

Should and will "cultured meat" become a reality in our plates?

Produced from proliferating cells in bioreactors with a controlled culture medium, "cultured meat" has been presented by its supporters, who are mainly private actors (start-ups), as a sustainable solution to meet the growing demand for animal proteins without weaknesses of animal husbandry in terms of environmental impact, animal welfare or even health. The aim of this chapter is to take stock of current knowledge on the potential benefits and pitfalls of this novel product. Since robust scientific arguments are lacking on these aspects, there is no consensus on the health and nutritional qualities of "cultured meat" for human consumption and on its potential low environmental impact.

Consumer Perception of Beef Quality and How to Control, Improve and Predict It? Focus on Eating Quality.

Quality refers to the characteristics of products that meet the demands and expectations of the end users. Beef quality is a convergence between product characteristics on one hand and consumers' experiences and demands on the other. This paper reviews the formation of consumer beef quality perception, the main factors determining beef sensory quality, and how to measure and predict beef eating quality at scientific and industrial levels.

Does the future of meat in France depend on cultured muscle cells? Answers from different consumer segments.

This research aimed to study the perception of French consumers on "cultured meat". The respondents (n = 5418) are characterised by an over-representation of young people, meat professional or scientists compared to the French population. Approximately 40-50% of them believed that animal husbandry faced ethical and environmental issues.

Brazilian Consumers' Attitudes towards So-Called "Cell-Based Meat".

The main goal of this online survey was to investigate the attitudes of Brazilians towards "cell-based meat", which has become the subject of great scientific and media enthusiasm. The answers of 4471 respondents concluded that 46.6% of them thought "cell-based meat" was promising and acceptable.

Are Marbling and the Prediction of Beef Eating Quality Affected by Different Grading Sites?

For the European abattoirs, the preferred carcass grading site is at the fifth rib, and cutting at the tenth rib as in Australia could lead to a lower economic value of the carcass. Therefore, the objective of this study was to compare the grading scores of marbling and the meat and fat color on (LTL) at the fifth and the tenth thoracic vertebrae. The consequences on the prediction of beef eating quality using the Meat Standards Australia (MSA) grading scheme were also evaluated for cull cows, which produce the majority of beef consumed in France.

Chinese Consumers' Attitudes and Potential Acceptance toward Artificial Meat.

The interest for artificial meat has recently expanded. However, from the literature, perception of artificial meat in China is not well known. A survey was thus carried out to investigate Chinese attitudes toward artificial meat.

Analysis of Scientific and Press Articles Related to Cultured Meat for a Better Understanding of Its Perception.

Cultured meat is presented by its advocates as a good alternative for consumers who want to be more ethically minded but who do not wish to change their diet. This novel food has become an emerging topic in both the scientific field and the press media. From a bibliometric analysis of scientific publications and on a sociometric analysis of the mainstream press, the aim of this study was to identify potential differences between the scientific view and the public perception.

European conformation and fat scores of bovine carcasses are not good indicators of marbling.

Marbling is one of the primary carcass attributes utilized in most beef grading systems for eating quality evaluation. In Europe, the current beef grading system is the EUROP grid, which is focused on carcass commercial value and production yield rather than eating quality estimation. The aim of this study was to investigate the relationship between marbling and the most common scores for carcass classification in Europe.

Contributions of tenderness, juiciness and flavor liking to overall liking of beef in Europe.

This study evaluated the contributions of sensory traits to overall liking in Europe. Perceptions by untrained consumers of tenderness, juiciness, flavor liking and overall liking were determined using the Meat Standards Australia protocols. According to European consumer testing with European beef samples, flavor liking was the most important contributor (39%) to beef overall liking, followed by tenderness (31%) and juiciness (24%) (P < .
