Rapid detection of lipid oxidation in beef muscle packed under modified atmosphere by measuring volatile organic compounds using SIFT-MS
Original language description
The objective of this work was to evaluate the use of a direct analysis technique (SIFT-MS) to measure the lipid oxidation process in beef meat packed under high oxygen atmosphere and compare it to conventional techniques such as gas chromatography-massspectrometry analysis and TBARS values. Meat samples from two suppliers were selected and packaged under the same atmosphere conditions. The fatty acid content, the physicochemical (TBARS and volatile compounds) and sensory parameters were measured. Thesamples from supplier 2 had a highest content of PUFA and n6 fatty acids that was related with a highest oxidation during storage. SIFT-MS and SPME-GC-MS detected a significant increase for most of the volatiles compounds analyzed during storage especially, in aldehyde compounds. High correlation coefficients between TBARS values and linear aldehydes (C3-C7) measured by both techniques were obtained and this indicates that SIFT-MS can be used to monitor lipid oxidation changes.
