Abstract:Population growth，greenhouse effects，and environmental degradation may lead to a shortage of animal protein foods depending mainly on livestock and poultry breeding.Moreover，this has resulted in increased attention to artificial meat，leading to a fierce competition in this field.As an emerging technology in the food industry in the 21st century，the research and development of artificial meat，such as plant-based protein meat and single-cell bacterial protein meat，has made great progress.Although industrialization is advancing rapidly，and cell culture meat is already being commercialized，key technological breakthroughs are lacking.This article summarized the types and characteristics of artificial meat，their research status，the key technologies required，and existing problems.
