Cultivated Beef Meat Has the Potential to Maintain Original Characteristics of Beef Meat with Customizable Features

Abstract Cultivated meat (CM) is currently attracting much attention because of its promise to become a solution to issues of environmental sustainability, animal welfare, and decarbonization. While the fabrication process and materials are still the main focus, it is not yet clear what the characteristics of the constructed CMs are and how they take on the original characteristics of beef meat. In this study, the biological, physicochemical and sensory characteristics of three types of beef (Wagyu, Crossbreed and Holstein) meat were systematically analyzed and compared to muscle and fat fibers constructed by three-dimensional printing using satellite and adipose-derived stem cells isolated from these beef meats. The different characteristics of each beef meat were largely taken on by the CM fibers composed of bSC and bADSC of each meat. In addition, some differing properties from those of the respective beef meat were observed in CM fibers such as one of the omega-3 fatty acids, docosahexaenoic acid (DHA; Wagyu fat fibers showed the highest amount). Furthermore, we also found the important possibility to increase the composition of oleic acid to over 80% in monounsaturated fatty acid (Wagyu has around 50% oleic acid). This study revealed the importance of using cells isolated from each beef meat to provide CM that closely resemble the original texture and taste of each meat, and further the possibility of more carefully arranging their properties.
