Abstract
The aim of this study was to investigate the effect of ethanol treatment on the properties of egg yolk gels (EYG). The hardness of EYG showed an increasing trend, and the changes in free sulfhydryl groups manifested that ethanol treatment facilitated the formation of disulfide bonds. Environment scanning electron microscopy revealed that the degree of protein aggregation increased. Low-field nuclear magnetic resonance results indicated that ethanol treatment promoted the conversion of immobile water or lipids to free water or lipids. Moreover, the increase in the absolute of zeta potential was accompanied by the decrease in surface hydrophobicity, and the secondary structure of native egg yolk (EY) proteins underwent changes with ethanol treatment. Overall, these results demonstrated that ethanol treatment induced the structural unfolding and aggregation of EY proteins, and facilitated the better stability of the gel structures. The impact of the ethanol on the EYG increased with the concentration.
