Cultured meat and challenges ahead: A review on nutritional, technofunctional and sensorial properties, safety and legislation.

Cultured meat is introduced as a valuable traditional meat equivalent. However, before marketable end products are available, several hurdles need to be overcome. Among others, these issues comprise obtaining an optimal nutritional profile and approaching the texture, the colour and the unique flavour and taste of conventional meat. Furthermore, the impact of processing on these matters is also still subject of future research. Moreover, more profound knowledge on food-safety aspects, like microbial contamination, prions, possible genetically engineered starting material, etc., and ways to reduce such risks will determine the future success of cultured meat products. Undoubtedly, correct terminology and adequate definitions also require further attention, as these form the starting point of legislative/regulatory aspects. This review provides a state-of-the-art overview on nutritional, technofunctional and sensorial properties, and food-safety and legislative/regulatory aspects on cultured meat production. Additionally, the various challenges and future steps of these aspects of cultured meat are highlighted.
