Recent technological developments and future trends in the evaluation and prediction of beef sensory quality in Brazil and France
No full textInternational audienceBrazil and France, which are two major beef players, continue to consolidate and strengthen their respective positions on international beef markets. This review summarizes Brazil's and France's recent technological developments in this sector, tracing the recent evolution of their beef markets with attention to indicators of quality, meeting consumer expectations, as well as to future trends in new techniques for predicting beef sensory quality. In addition, this review will focus on the feasibility of implementing the Meat Standards Australia (MSA) grading protocols (known internationally as the Guaranteed Global Grading (3G protocols) by the International Meat Research 3G Foundation. Implementations of the MSA/3G grading scheme as recommended by the United Nations Economic Commission for Europe (UNECE) are particularly attractive because of MSA's proven record of increasing the reliability and accuracy of predictions of the sensory quality of beef through the use of pre- and post-slaughter factors. Additionally, the feasibility of new technologies for assessing the eating quality of beef has been evaluated by comparing the marbling scores of beef given by accredited graders for the MSA/3G method with those obtained using portable devices based on these new technologies. In this way, it is expected that implementation of the MSA/3G methodology and nondestructive techniques to evaluate the quality and safety of beef in Brazil and France will more reliably predict and further improve sensory quality, similar to what has already been implemented elsewhere

Food of the Future: Meat and Dairy Alternatives
No full textInternational audienceIn recent years, there has been increasing discussion about the impact of our dietary choices not only on our health, but also on global issues such as food security and climate change. Much emphasis has been placed on eating a plant-based diet and avoiding foods of animal origin, with vegetarian options becoming far more abundant across grocery stores and in restaurants. But are we on the right direction? Will meat and dairy alternatives satisfy consumers by living up to their promises? To contribute to this debate, 11 articles have been published in this special issue including 5 on what is called “cultured meat,” 4 on plant-based meat/dairy alternatives, and 2 on “hybrid meat” or other alternatives
Chapter 5 - What should the properties of cultivated meat be?
No full textInternational audienceThis chapter explores the safety, nutritional value, and sensory quality of cultivated meat (CM) and evaluates both the potential and limitations of this technology. Given the complexity of the biological process, there is little possibility of producing muscle fibers with an appearance, composition, and structure close to those observed in vivo . Further studies are needed to assess the potential beneficial effects of micronutrients provided by cultivated cells. As the properties of micronutrients vary according to the support matrix used for CM growth, the health benefits of these compounds will also vary. Digestibility of nutrients from CM also needs to be studied.Proponents of CM claim that CM will be safer for consumption than traditionally sourced meat. However, as with any new technology, there is no such thing as zero-risk innovation, as consequences and risks are not fully predictable. Although most CM manufacturers have now abandoned the use of both, proof of concept for CM was achieved using antibiotics prophylactically in processing and using fetal bovine serum (FBS) for cell growth. Further scientific research is essential before CM can represent an alternative source of animal proteins

Travail agricole et transition agroécologique : quelles interactions, quels impacts et quelles conséquences pour la formation en agronomie ? [Éditorial]
No full textNational audienceCe numéro d’Agronomie, environnement & sociétés s’inscrit dans le prolongement du numéro précédent qui a traité des enjeux, des impacts et des conséquences pour l’agronomie de l’évolution du travail en agriculture, en lien avec la transition agroécologique. Mais dédié au public d’agronomes formateurs et d’apprenants, ce numéro est original par la proposition de textes qui visent à donner envie aux formateurs de mieux prendre en compte dans leurs enseignements les différentes dimensions du travail en agriculture, en particulier dans une dynamique de trajectoires agroécologiques. Ce numéro est issu des travaux de deux événements concomitants qui se sont déroulés au cours de l’année 2023/2024 : les Entretiens Olivier de Serres et leur déclinaison en région Auvergne Rhône-Alpes pour un public en formation, les Entretiens Olivier de Serres juniors. Dispositif qui a permis d’engager, en région, une dizaine d’établissements publics de formation agricole avec un travail en local dans des exploitations agricoles et un rassemblement conclusif au lycée agricole d’Aubenas (07)
