Special Issue Information

Dear Colleagues,

Eggs are one of the important agricultural products in people's daily lives due to their excellent nutritional and functional characteristics. Thus, the study of the processing and physicochemical properties of egg cannot be ignored in food science; therefore, the following must be studied. Firstly, processing of the diversified egg products, such as preserved eggs, salted eggs, liquid eggs, functional egg products, high-value egg products, and so on. Secondly, how to improve the functional properties (such as foaming, emulsifying, and gelation) of eggs and their mechanism. Thirdly, expanding the application of eggs in the fields of food, biology, and medicine based on the prominent nutritional and physicochemical properties of egg white, yolk, or eggshell. In addition, the study of the molecular interactions and mechanisms between proteins in eggs and other chemical components in the food system, such as polysaccharides, lipids, and polyphenols is also necessary to understand their processing or physicochemical properties.

Abstract
Preserved egg white (PEW) has excellent gelling properties but is susceptible to the freshness of raw eggs. In this study, the correlation between the comprehensive freshness index (CFI) of raw eggs and the gelling properties of alkali-induced egg white gel (EWG) was elucidated. [...] Read more.
Preserved egg white (PEW) has excellent gelling properties but is susceptible to the freshness of raw eggs. In this study, the correlation between the comprehensive freshness index (CFI) of raw eggs and the gelling properties of alkali-induced egg white gel (EWG) was elucidated. Results showed that the CFI, established by a principal component analysis (PCA) and stepwise regression analysis (SRA) methods, can be used to predict the freshness of duck eggs under storage conditions of 25 °C and 4 °C. A correlation analysis demonstrated that the CFI showed a strong negative correlation with the hardness and chewiness of alkali-induced EWG and a strong positive correlation with resilience within 12 days of storage at 25 °C and 20 days at 4 °C (p < 0.01). It might be due to the decrease in α-helix and disulfide bonds, as well as the hydrophobic interactions showing a first decrease and then an increase within the tested days. This study can provide an important theoretical basis for preserved egg pickling. Full article
