Abstract

The apples of Red Delicious are round fruits that have red colour when ripe according to which they are named. They can be
eaten fresh, but also can be processed into a variety of processed products including apple juice. In order to grow or obtain better
yield of a good quality apples, pesticides are usually used to protect apple trees, but they can adversely aff ect human health,
therefore, some precautions should be taken when these chemicals are used as food contact materials. This study summarizes
the presence of chlorpyrifos pesticide residues in apples that are prepared by diff erent methods including mechanical treatments,
fresh, washed, peeled as well as heat treatment of apples when prepared into an apple juice. For this purpose, the QuEChERS
(Quick, Easy, Cheap, Eff ective, Rugged and Safe) method was used for residue extraction in apple samples after diff erent methods
of preparation, and their analyses were performed by liquid chromatography-mass spectrometry (LC-MS/MS). The concentration
of the pesticide chlorpyrifos in diff erent samples of apples was in the range of less than 0.0005 mg.kg-1 to 0.00348 mg.kg-1. This
study provides a conclusion that all samples of apples are safe for consumption while the peeling method and heat treatment are
the most effi cient in reduction of chlorpyrifos content in the fi nal products.
