Combining quantitative lipidomics with meat quality traits to identify key lipids involved in intramuscular fat deposition in geese.

ABSTRACT: This study utilized the O2PLS model to successfully integrate multidimensional data from meat quality traits and quantitative lipidomics, identifying key lipids involved in lipid deposition in goose meat. Meat quality analysis showed higher intramuscular fat content in goose meat during the sexual maturity phase. Lipidomics techniques were subsequently applied to elucidate differences in breast muscle lipid profiles between the growth phase and sexual maturity phase. Using UPLC-ESI-MS/MS, 298 lipids were identified as significantly altered. Unsupervised principal component analysis was employed to identify characteristic lipids distinguishing the two stages. As expected, phospholipids emerged as the key metabolites differentiating developmental stages, with three phospholipids identified i
