com The need for alternative sources of protein As the global population is expected to approach 9.7 billion by 2050, it remains crucial to ensure the adequate and sustainable production of nutritious food. The demand for protein is especially concerning, as traditional sources like livestock are insufficient and significantly contribute to greenhouse gas (GHG) emissions.
Expanding agriculture to meet predicted protein demands will inevitably threaten biodiversity and accelerate environmental degradation. As a result, significant investments have been made in improving the appearance and texture of alternative protein (AP) products to more closely resemble animal-based products. The AP market currently comprises plant-based, insect-based, and microbe-derived protein sources, as well as cultured meat and seafood products.
In 2023, the AP market size was estimated at $15.3 billion United States dollars (USD) and is expected to reach $26.5 billion USD by 2030.
Although APs offer promising solutions to environmental and health issues, they are associated with several challenges including consumer acceptance, high production costs, and regulatory issues. Despite growing interest and market potential, th.
