Abstract

Fresh intact lamb muscle was measured using a Raman hand held device to determine the ability of Raman spectroscopy to predict intramuscular fat (IMF) and fatty acid (FA) composition. Raman measurements were conducted on 80 samples of longissimus thoracis lumborum (LL) from different carcases. Measured FA values were regressed on the Raman spectra using partial least squares (PLS) regression. Predicting polyunsaturated fattyacids (PUFA) yielded a squared correlation between predicted and measured values (R2cv)equal to 0.56 and a root mean square error of cross validation (RMSECV) of 16.2mg/100g meat. Prediction of PUFA: saturated fatty acids (SFA) gave an R2cv equalled to 0.15 and aRMSECV of 0.04. This is the first Ramanspectroscopy study to measure FA composition of IMF in intact muscle and there is evidence to suggest that Raman spectroscopy has the potential to predict PUFA and PUFA:SFA ratio. Further work is required to validate the models generated in this study and establish the potential benefit of Raman spectroscopy.
