Extract

The potential of Raman spectroscopy for the analysis of fats and oils has been recognised for some decades. The main advantages of the technique are that no sample preparation is required (allowing in situ or on-line studies) and that it can be applied to any physical state including gases, liquids, gels, amorphous solids and crystals. The power of Raman spectroscopy to discriminate between cooking oils has previously been demonstrated. Beattie et al (2004a) demonstrated the use of Raman spectroscopy for the characterisation of lipids in model systems and also in clarified butterfat (Beattie et al 2004b). The aim of this paper was to determine whether Raman spectroscopy could discriminate between the adipose tissue from different species and which characteristics of the lipids (i.e chain length , unsaturation) contributed to the discriminating functions.
