Abstract: In recent years, researchers have often modulated the sensory and functional properties of foods through the interaction among various food components. Phenolic acids, proteins and carbohydrates widely exist and play important roles in flour products. Until now, existing studies primarily concentrate on the interactions of phenolic acid with protein and carbohydrate, along with their applications in several fields such as food processing and healthcare. The intricate interactions in the phenolic acid-protein-carbohydrate ternary system impart different sensory and functional properties to flour products. In this article, we review the research progress on the interactions among phenolic acid, protein and carbohydrate and their influence on the sensory and functional properties of bread dough, hoping to provide theoretical guidance for the application of the ternary system composed of phenolic acids, proteins and carbohydrates in flour products.

Key words: phenolic acid; protein; carbohydrate; interaction; ternary system
