Abstract EN
This study investigated relationship between secondary structure and surface hydrophobicity of soy protein isolate (SPI) subjected to a thermal treatment at 70~90°C.
Heat denaturation increased the surface hydrophobicity and surface hydrophobicity decreased as aggregate formed.
Heat caused an increase in the relative amount of α-helix structures and an overall decrease in the amount of β-sheet structures when compared with nontreated SPI.
The relative amounts of secondary structures varied with time, temperature, and intensity of heat treatment applied.
The β-sheet structure was most important for its significant role in denaturation of 7S globulin and following formed aggregates and even in denaturation of 11S globulin.
The amount of β-sheet structure in SPI had an inverse correlation with the surface hydrophobicity when the temperature was kept below 90°C.
Besides, β-turn structure increased as β-7S/B-11S aggregate formated.
