摘要

•Ultrasound treatment (PUS) could increase lipid and protein oxidation significantly.•Protein aggregation occurred according to SDS–PAGE analysis.•Free sulfhydryl contents and protein surface hydrophobicity increased after PUS.•FTIR showed the increases in β-sheets while decreases in α-helix structures after PUS.
