This study addresses the need for effective protein extraction and characterization to unlock the potential of underutilized plant resources like Brosimum alicastrum Swartz nuts, aiming to enhance their value as functional ingredients in food applications. Extraction methods, including pH modulation, ultrasound-assisted extraction, and enzymatic hydrolysis, are employed to enhance technofunctional and bioactive properties. The protein extracts are evaluated for solubility, emulsifying capacity, foaming properties, and water/oil-holding capacities to assess their technofunctional potential. Additionally, the bioactive properties, such as antioxidant and anti-inflammatory activities, are analyzed to explore potential health benefits. The results demonstrate that integrated extraction techniques significantly improve the yield and quality of Brosimum alicastrum Swartz nut proteins. Enzymatic hydrolysis, in particular, produces hydrolysates with superior bioactive properties. These findings highlight the potential of Brosimum alicastrum Swartz proteins as valuable ingredients for the food and pharmaceutical industries, promoting the utilization of underexploited plant resources for sustainable and health-promoting applications.
