AVALIA??O DE RESíDUOS DE AGROTóXICOS EM POLPAS DE MORANGO INDUSTRIALIZADAS

摘要

Samples of industrialized strawberry pulps, commercialized in Minas Gerais state, Brazil, were collected in the period from 2006 to 2007 by the Sanitary Surveillances, and were sent to Fundação Ezequiel Dias for analysis of pesticide residues. It was performed the extraction by multi-residue method with acetone, dichloromethane and hexane. The obtained extracts were analyzed by gas chromatography with detectors of electron capture (GC-ECD), flame photometric (GC-FPD), nitrogen phosphorus (GC-NPD), mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) with UV visible and fluorescence detectors. The results showed the inappropriate use of pesticides, which are not authorized as acephate, captan, chlorfenapyr, chlorpyrifos, dimethoate, omethoate, endosulfan, fenarimol, folpet, methamidophos, prochloraz and tetradifon, and the permitted ones azoxystrobin, difenoconazole, fenpropatrina, iprodione and procymidone. These indicate that good agricultural practices are not being followed by some producers, and demonstrate the necessity of processed food fiscalization, which will lead to products of better quality.
