Some applications of a home-made SFE (Supercritical Fluid Extraction) system in the analysis of pesticides residues and essential oils in food are reported. Several studies with modification of the parameters: temperature, pressure, choice and concentration of modifiers were developed. The results of pesticides residue analysis are presented for passion fruits (organophosphorus and pyrethroids pesticides), honey (organochroline pesticides) and oranges (essential oils).
