used to screen for diagnostic central nervous system (CNS) lipid markers in meat
products. This is of particular interest for risk assessments studies for bovine
spongiform encephalopathy (BSE) and food labeling legislation. The ASE
fractionation scheme worked better than the widely used exhaustive lipid
extraction procedure followed by SPE with regard to lipid recoveries and clean
fractionation of the lipid classes. Clearly, the combination of temperature, solvent,
and adsorbent materials in the ASE cell can provide unique selectivity and
capability and provide additional advantages over other sample preparation
techniques.
