Plant-based proteins: functional, nutritional, and technological advances for sustainable food systems
摘要
Plant-based proteins are sustainable, ethical, and nutritionally rich alternatives to animal-derived proteins. Sources such as legumes, cereals, pseudocereals, oilseeds, algae, and duckweed provide essential amino acids, dietary fibre, and bioactive compounds. Their functional properties, including emulsification, foaming, gelling, and thickening, support applications in meat analogues, dairy substitutes, and nutraceuticals. Recent technological innovations have enhanced protein purity, digestibility, and functional performance while reducing environmental impact. Plant proteins also offer health benefits such as antioxidant activity, cholesterol reduction, muscle maintenance, and gut microbiota modulation. This review highlights recent technological innovations and future trends, including computational modelling, 3D printing, and AI-driven formulation, for scalable, consumer-friendly protein solutions. Plant proteins are poised to become key components of sustainable, health-promoting food systems.
