摘要：The aim of this work was to study the main chemical changes in the protein fraction (SDS-PAGE) and the microstructure (TEM) of whole liquid egg treated with HPH and stored one week at 4°C. In the electrophoretic study, no changes were observed after the treatments neither after one week of refrigerated storage in the water-soluble proteins of the samples, indicating that no proteolysis was produced. The typical structure of the egg lipoprotein matrix was maintained after the HPH treatments and one week of refrigerated storage. However, a progressive disaggregation of the protein granules was observed, especially when high intensity HPH treatment was applied. It was attributed to the HPH treatment and the microstructural changes observed could affect the functionality of the whole liquid egg when it is used as an ingredient in foodstuffs.
