Abstract:
Animal husbandry accounts for a large proportion of global total land use and greenhouse gas emissions. In addition, prophylactic antibiotics are widely used in the process of large-scale animal breeding, resulting in drug-resistant bacteria, other pathogenic factors, and zoonotic diseases. More importantly, as the human population grows, the ever-growing demand for meat and dietary proteins cannot be satisfied by traditional animal husbandry. Therefore, cell-based meat production technology has emerged and developed rapidly. It displays potential to provide meat protein products without related environmental, ethical and technical issues. Although protein supply shortages due to the growing global population could be solved by cell-based meats, current key breakthrough technologies required for cell-based meat production are limited to laboratory scale research and production. Many technical bottlenecks in mass production of cell-based meat need further investigations. Based on the current status of the traditional husbandry industry and technology development trends within the cell-based meat production field, this review illustrates the potential for cell-based meats to supplement the meat supply provided by traditional animal husbandry, its market positioning, and trends in development of key future technologies.
