Interpretive Summary: Soybeans are a critical source of protein for food products, animal feed, and industrial applications, but their genetic diversity in the U.S. is limited. This lack of diversity hinders the development of new soybean cultivars with improved protein quality, enhanced functionality, and greater stability under different environmental conditions. Understanding how genetic differences influence soy protein properties is essential for optimizing its performance across various applications. This study revealed significant genetic variation in key protein characteristics among diverse soybean cultivars, affecting solubility, emulsifying ability (important for mixing oil and water), and foaming capacity (essential for food texture and processing). The study also highlighted how balancing protein structure and hydrophobicity can improve overall soy protein functionality. These findings provide valuable insights for soybean breeders and food scientists, guiding the development of improved soybean varieties with enhanced protein performance for food and industrial applications. By leveraging genetic diversity, this research supports efforts to produce soybeans with superior protein quality, benefiting both farmers and consumers.
