This article explores the pivotal role of R&D in cultured meat product development, detailing its current state, applications, benefits, challenges, and future prospects in creating a more sustainable food system.

Understanding Cultured Meat

Cultured meat is produced by extracting animal cells—typically muscle or stem cells—and cultivating them in a bioreactor filled with a nutrient-rich medium. These cells multiply and differentiate into muscle fibers, which are harvested and shaped into meat products like burgers, nuggets, or steaks. Unlike conventional meat, which requires raising and slaughtering animals, cultured meat is grown in a lab, offering a controlled and potentially more sustainable process. The concept gained global attention in 2013 when Dutch scientist Mark Post unveiled the first cultured beef burger, costing $330,000 to produce Good Food Institute. Since then, the industry has expanded rapidly, with over 175 companies across six continents and investments exceeding $3.1 billion by 2024, reflecting the transformative potential of this technology.
