Meat technology is a comprehensive field that encompasses the science and engineering of meat production, processing, preservation, and safety. This multidisciplinary domain draws on knowledge from biology, chemistry, food science, and engineering to develop methods for improving the quality, safety, and nutritional value of meat and meat products. At its core, meat technology addresses challenges in meat production and processing, ranging from animal husbandry to food safety, as well as consumer preferences and environmental sustainability.
The process of meat production begins at the farm level, where animal breeding, nutrition, and management practices significantly influence the quality of the final product. For instance, the selection of specific breeds can yield differences in carcass characteristics, meat tenderness, and fat composition (Mourad & Fischer, 2020). Proper nutrition during the growth phase is also critical; for example, the inclusion of omega-3 fatty acids in livestock feed has been shown to enhance the nutritional profile of the meat (Sullivan et al., 2019).
Once the animals are slaughtered, the focus of meat technology shifts to processing, which can include a variety of techniques such as cutting, grinding, and curing. During these processes, factors such as temperature, pH, and microbial contamination play crucial roles in determining the safety and quality of the meat. The application of thermal processing methods, like pasteurization, can mitigate pathogenic microorganisms, while also extending shelf life (Zhang et al., 2021). Moreover, advancements in meat curing technology, such as the use of natural preservatives like rosemary extract, have gained popularity for their ability to inhibit spoilage while catering to the increasing consumer preference for clean-label products (Borch et al., 2021).
Another significant aspect of meat technology is the control of spoilage and foodborne pathogens. The use of modern packaging techniques, such as vacuum packaging and modified atmosphere packaging, has revolutionized the meat industry by significantly extending shelf life and maintaining product quality (Gheorghe et al., 2018). These technologies work by limiting oxygen exposure, thereby reducing the growth of aerobic bacteria and oxidative spoilage.
Furthermore, there has been a surge in consumer demand for value-added meat products, leading to innovations in processed meat alternatives. The rise of plant-based alternatives and cultured meat products represents a paradigm shift in the meat sector (Tuomisto & Teixeira de Mattos, 2011). Companies like Beyond Meat and Impossible Foods are pioneering these developments, utilizing food technology to create plant-based products that mimic the texture and flavor of traditional meat items. These innovations not only cater to health-conscious consumers but also address sustainability concerns associated with conventional meat production.
Food safety remains a paramount concern within meat technology. The principles of Hazard Analysis Critical Control Point (HACCP) have become integral to meat processing establishments, ensuring that potential hazards are systematically identified and controlled throughout the production process (Ferguson et al., 2018). Regular microbial testing and monitoring of critical control points help maintain the highest standards of food safety.
In summary, meat technology encompasses a broad spectrum of practices and innovations that influence the production, processing, preservation, and safety of meat. By integrating scientific and technological advancements, the field continues to evolve, addressing the demands of a changing consumer landscape while also confronting challenges related to food safety and sustainability. As the industry moves forward, ongoing research and development will be essential in refining meat technology practices and exploring new avenues for ensuring quality and safety in meat production.
