The Multifunctional Role of Soybean (Glycine max L.): Its Nutritional Value, Industrial Potential, and Future Projections

OpenAlex English

Soybean (Glycine max L.) has been a cornerstone of East Asian cuisine throughout human history, but in the last century, it has become a global agricultural commodity and economic powerhouse. It holds strategic importance as both a direct food source for human consumption and a key protein source for the livestock sector. The rising global population, changing dietary habits, and increasing demand for animal protein further underscore the importance of soybeans. The plant's high-quality protein and oil content, along with its full complement of essential amino acids, make it an indispensable protein source in both human nutrition and the animal feed industry. The versatility of its uses, ranging from food products (tofu, soy milk) to industrial applications (biodiesel, bioplastics), highlights its multifaceted economic value. This review examines the broad applications, importance, and future potential of the soybean, one of the most significant cultivated plants globally, within our food systems. In the face of challenges posed by population growth and climate change, innovative approaches such as genetic engineering, smart farming, and agroecological methods will help maximize the economic potential of soybeans while minimizing their environmental footprint. These approaches will ensure that soybeans remain a fundamental resource for our food security in the future.
