Abstract

Ruminant meats contain functional lipids including fatty acid esters of hydroxy fatty acids (FAHFA), diglycerides (DG), monoacetyldiglycerides (MAcDG) and medium chain triglycerides (McTG) whose consumption in the normal diet can confer benefits for consumer health. However, very little is known concerning how meat processing techniques such as marination and grilling affect the quantity and quality of these functional lipids in ruminant meats. We used ultra high-performance liquid chromatography coupled to high resolution accurate mass tandem mass spectrometry (UHPLC-HRAM-MS/MS) to show how grilling following marination with either India or Wheat ale unfiltered beer-based marinades affected the quantity and quality of these functional lipids in ruminant meats. We observed MAcDG was completely degraded in grilled meats. Both unfiltered beer-based marinades retained higher (P
