This study investigates alternative protein trends, including research and related companies focusing on both domestic and international markets. Various studies are necessary as interest in alternative protein foods has significantly increased due to the recent rise in the vegan population and concerns about environmental pollution caused by the animal welfare and livestock industries. The alternative protein market is expanding globally, with Europe accounting for 39% of the market share, while the United States, Asia, Australia, and New Zealand are gradually developing their alternative protein markets. There are four types of alternative protein foods: i) plant-based alternatives with high protein content, ii) animal cell-derived alternatives with controlled fatty acids and iron content, iii) microbial-derived alternatives combined with high protein and additional nutrients, and iv) edible insects rich in protein and mineral substances. Although various research efforts are underway on alternative protein foods, the domestic industry is still in its early stages, necessitating significant investments in government support, further technological development, and alternative protein R&D. Therefore, this research study can provide foundational data for the development of alternative protein foods by offering insights into the current status of domestic and international research in this field.
