Abstract
Xylitol and NaCl were studied as alternative inhibitors of gelation in frozen egg yolks, considering the current dietary preference for low salt and low sucrose intake. The effects of different ratios of xylitol and NaCl on gelation were investigated. Compared to the control group, all treatment groups showed decreased egg yolk particle size and turbidity, increased solubility, surface hydrophobicity, λmax, and fluorescence intensity, reduced loss of free water, and enhanced yolk fluidity. The addition of xylitol and NaCl effectively prevented ice crystal growth, minimized protein denaturation caused by water loss, and formed complexes with proteins and water lost during freezing, thereby inhibiting the aggregation of protein molecules and the formation of gels. This study presents a novel and healthier strategy for inhibiting gelation of frozen egg yolk using xylitol and NaCl.
