摘要: The variation in thawing time, deterioration behavior, secondary structure, surface hydrophobicity, and average particle size of frozen egg whites (EW) thawed with or without ultrasound were characterized to evaluate the effect of ultrasound on the gel properties and volatiles of egg white thermogel (EWG). The texture, water holding capacity, etc., gel properties and microstructure were well maintained in frozen EW thawed by ultrasound (UEW) resulted from the mitigation of deterioration behavior due to shorter melting time (reduced 91.3 %). Moreover, the deterioration of VOCs in fresh EWG due to freeze-thawing could be mitigated when thawed using ultrasound. Meanwhile, the formation of pleasant VOCs and reduction in unpleasant VOCs in EWG were also promoted by ultrasound-assisted thawing. The improvement mechanism of gel properties and volatiles for (frozen) egg white melted assisted with ultrasound were systematically elucidated and this study provided a new insight into improvement of VOCs in frozen food.
