Food Proteins: Role in Structural and Functional Properties of Food Systems

Food proteins play a crucial role as fundamental components in both the nutritional aspects and structural framework of contemporary food systems. This review thoughtfully explores their dual purpose—providing essential amino acids vital for health while also enhancing the structural robustness and functional capabilities of food items. Ranging from dairy and meat proteins to modern plant-based and alternative protein sources, each type demonstrates distinct properties such as gelation, emulsification, water-binding, solubility, and foaming. These characteristics directly affect the texture, appearance, stability, and taste of food. Furthermore, environmental and processing factors such as pH, temperature, and enzymatic treatments significantly impact protein functionality. As the food industry transitions towards more sustainable, nutritious, and functional offerings, the exploration of food proteins is becoming increasingly important. This article highlights the essential significance of comprehending food proteins by illustrating their vital contributions to food formulation, product development, and future innovations.
