Abstract
Lactones, particularly those with γ- and δ-structures, play a pivotal role in shaping the sensory attributes of dairy products, with their formation being strongly influenced by the intensity of heat treatment. This study investigated the changes of lactones in milk under different heating treatments and analyzed their correlation with lipids. Solid-phase micro-extraction coupled with gas chromatography-mass spectrometry was used to analyze the types and concentrations of lactones. The results revealed that lactone content increased with increasing temperature. Lipidomic analysis identified 73 triglycerides that exhibited notable variations across the samples, highlighting their role in lipid degradation processes that modify free fatty acid profiles. Principal component analysis further demonstrated how specific triglycerides and free fatty acids undergo differential decomposition under varying heat conditions, thereby influencing lactone profiles. This study provided new insights into the mechanisms of lactone formation and their regulation during milk processing, offering strategies to optimize lactone composition in dairy products through precise heat treatment control.
