Alternative protein sources have emerged as a significant topic from an agricultural perspective. Alternative protein sources include alternative plants, algae, fungi, insects, microbial proteins, in vitro or artificial meat, dairy-free vegan cheese, and other products produced through technologies such as biofermentation. The integration of alternative protein sources into agricultural production systems is seen as an important step towards a sustainable food system. This integration not only helps reduce environmental impacts but also plays a key role in meeting the protein needs of the growing global population in the future. This study was prepared to reveal the agricultural importance of alternative protein sources.
