As global consumer preferences shift towards ethical and sustainable plant-based foods, the processing of plant proteins has become a critical area of study. This book explores the inherent challenges and vast potential of plant proteins, which, despite their versatility and cultural acceptance, often require modification to match the superior functionality of animal proteins. It presents a comprehensive roadmap of scientific studies and techniques aimed at enhancing the techno-functional properties, bioactivity, bioavailability, and digestibility of plant proteins for future food and pharmaceutical applications.
