Abstract
This study assessed the nutritional and biological properties of Nigerian soybean. Methods: Soybean seeds were treated into flour, soybean flour (SBF), and used for nutrients composition evaluation. SBF was modified into pellet diet (SBD) for a 14-day feeding study with healthy male Sprague Dawley rats. Key metrics such as body weight, feed intake, and feacal output were monitored over the last four days. Findings: Soybean flour had a higher energy percent for protein (38.24 E%), lipid (40.20 E%), but lower energy percent for carbohydrate (21.56 E%) compared with the recommended values. Also, in the findings, moisture, ash, fibre content, and the density of iron, zinc and calcium were within recommended range, the biological quality was considerable for net protein ratio (2.19), true digestibility (85.25%), but not substantial for protein efficiency ratio and protein digestibility corrected amino acid score. The sulphur amino acid was the limiting amino acid. Conclusion: The current study had demonstrated that soybean is a rich source of protein, lipid, iron, zinc and calcium, but with low carbohydrate content. Thereby giving the insight into the potentiality of soybean protein as an alternative for animal protein in making a protein-rich-source food through complementation with poor plant-based food.
