Solvent was evaporated under a nitrogen stream and lipid content was gravimetrically
determined. Besides, it was checked that the fatty acid profile was not altered by the protocol used. Moreover,
the analysis of 4 replicas from the same sample showed different variation coefficients (16–29%) for the
new procedures proposed over a wide range of IMF content. The combination of Grinder and Vortex methodologies
can be proposed as a simple and inexpensive alternative to previous ones.
