Molecular weight profiles confirmed that both methods effectively preserved major storage proteins, including 7S and 11S globulins and 2S albumins. Secondary structural analyses revealed pronounced pH-induced denaturation in alkaline extracts, versus high α-helix retention in DES–US samples (e.g., DES-GLU 95.7 %, DES-SOR 81.6 %). DES–US systems also exhibited higher solubility (75–76 %) compared to alkaline extracts (58–63 %).

Conversely, alkaline extracts demonstrated superior foaming capacity (∼50 % for ALK10) and stability (∼40–50 % at 120 min), while DES–US foams were less stable (∼10–25 % FC). In vitro digestibility was highest for DES–US isolates (DES-SOR ∼76 %, DES-GLY ∼75.1 %) compared to alkaline treatments (∼57.6–65.3 %).

The results suggested that PE effectively inhibited MP degradation based on the MP function and structure. After 5 F-T cycles, the protein solubility of MP from patties containing 0.5 % PE powder was significantly higher than the control (<em>P</em> < 0.05). Additionally, the inclusion of PE in patties could inhibit the decrease in whiteness and water-holding capacity, the WHC of MP gels in the control group started at 77.05 % and decreased to 48.67 % after 5 F-T cycles. In the experimental group, the WHC started at 83.81 % and decreased to 59.06 % after 5 F-T cycles. Scanning electron microscopy (SEM) images revealed that the freezing and thawing processes disrupted the regular aggregated structure of MP gels.

Furthermore, the inclusion of PE inhibited the degradation and structural unfolding of protein. After many F-T cycles, the carbonyl content of MP grew significantly from 1.85 nmol/mg to 11.69 nmol/mg.
