Pesticide Residues Evaluation in Pulp, Juice and Nectar of Fruits

Abstract

Industrial processing of fruit in order to produce juice and nectar can contribute to over exposure of some contaminants, such as pesticide residues. Thus, this work aimed to check the compliance with the Maximum Residue Levels (MRL). In our research, 162 samples of frozen pulps, 16 of juice and 2 of nectar, were evaluated for pesticide residues, as well as the acceptable dietary intake (ADI). A multi-residue method was employed and almost 140 active ingredients were studied. Positive results were detected only in pulps, corresponding to 40% of the amount of samples. According to the Brazilian and the Codex Alimentarius legislation, none of the pesticide residues found were above the MRL. The most frequently found compounds were: pyridaphenthion, azinphos-methyl and carbendazim in peach and endosulfan in strawberry samples. Multiple findings were found in strawberry (29.6%) and peach (7.8%). Chronic dietary intake was not exceeded. The results demonstrated the necessity of pesticide residue control in fruit.
