Abstract :In this study, five types of dates imported from different countries, namely Iran, Medina, Tunisia, Jerusalem, and Baghdad, were selected to determine the antioxidant activity properties of dates. In addition, 10 pesticide residues used in date plants were analyzed and the effects of pesticide residues on recovery using were investigated. Antioxidant activities of the date extracts were determined by using DPPH and Folin–Ciocalteu phenol reagent assays. Pesticide residue studies were performed by using LC-MS-MS technique and recovery studies were carried out by using AOAC.2007.01 and 15662 Quechers methods Antioxidant activity and total phenol contents of date fruit were affected by location, genetic variability, environmental characteristics, maturation stages, and extraction methods. A lot of residual pesticides were determined in the extracts. It was determined that the Dioxacarb residue in the Medina date fruit was above the tolerance limit. According to AOAC 2007.01 Quechers method, the highest recovery of Chlorpyrifos Methylin was found as 57.069 in Medina date. In the study, it was determined that date extracts showed lower antioxidant activity compared to standard antioxidants. Many pesticide residues were detected in the pesticide analyzes made on dates, and some of them were found to be above the specified limits. It is of great importance that the pesticide residue amounts in foodstuffs are determined beforehand and not exceed the tolerance limits, both in terms of consumer health and in terms of not returning the exported food products. Within the scope of the study, pesticide residues commonly used in Date fruit were analyzed and determined.Keywords : Antioksidan, Pestisit, Geri Kazanım, Hurma, LC-MS-MS
