The lipid content of 10 g pork mince and chop samples stored for 2, 5
and 7 days was determined using chloroform/methanol extraction,
according to Bligh and Dyer (1959), modified for using less amount of
solvent. Following evaporation of the solvent, the lipid content of the
extract was determined gravimetrically and expressed as percentage
of the initial sample weight.
