[Objective ] This study aims to reveal the interactions between collagen and volatile compounds during the cooking process.[Method ] The relative molecular weight,particle size,solubility,secondary structure,and surface hydrophobicity of collagen and the droplet size of the collagen emulsion were studied.Furthermore,the binding ability of collagen to volatile compounds of the aqueous and emulsion systems of collagen was measured.[Result ] As the heating time was extended,the triple-helix structure of collagen was destroyed and the polypeptide chains were degraded,which were accompanied with the decrease in surface hydrophobicity,increase in solubility,and heat-induced aggregation.The binding ability of collagen to volatile compounds gradually decreased with the extension of …
