Quantitative proteomics study on the changes of egg white of yellow preserved primary chicken eggs soaked in alkali solution

[Display omitted] •Proteomic expression on YPPEW were detected by TMT proteomic technology.•There were 100 DEPs, most of which were significantly related to quality traits.•Six pathways revealed the potential mechanism of biological functions of YPPEW. In order to investigate the changes of egg white of primary chicken eggs after being soaked in alkali solution, the tandem mass tags (TMT)-labeled quantitative proteomic technology combined with bioinformatics was conducted in this study. The results indicated that 100 differentially expressed proteins (DEPs) in yellow preserved primary egg white (YPPEW), 75 of which were highly and significantly correlated with the quality traits of YPPEW (| r | ≥ 0.9000, P
