Abstract:
To investigate the interaction mechanism between phospholipids and myofibrillar proteins (MP) during thermal degradation, Gas chromatography-mass spectrometry combined with thermal gravimetric analysis was used to analyze the effect of MP on volatile compounds and mass loss during the thermal degradation of phospholipids (PLs) (phosphatidylcholine and phosphatidylethanolamine). The addition of MP increased the number of volatile organic compounds generated during the pyrolysis of phospholipids from 10 to 17, including 5 aldehydes, 1 alcohol, and 1 ketone. At 100 °C, the pyrolysis loss of the MP and PL mixture exhibited altered thermal degradation patterns compared to PL or MP alone, suggesting interfacial interactions between the two components. Hexanal is the most significantly influenced compound by MP-double bond interactions, whereas 3-octen-2-one exhibits the highest sensitivity to MP-head group interactions. Thermal induced structural remodeling and radical-mediated oxidation cascade are the main mechanisms underlying the interaction between PL and MP.
