Abstract: This review presents an overview of analytical methods for the analysis of pesticide residues in fruit juices and vegetable paste. The most widely used detection technique for the determination of pesticides is mass spectrometry combined with gas chromatography. QuEChERS method was used for determining twenty seven pesticide residues as per standard guidelines of Association of Official Analytical Chemists (AOAC). The method involves extraction with acetonitrile, liquid-liquid partition with addition of MgSO4 and NaCl followed by dispersive SPE cleanup with PSA sorbent and the analysis was carried out with a GC-MS triple quad equipment. Three major groups of pesticides (organochlorine, organophosphorus and synthetic pyrethoids) were taken for study. The method was applied to 9 fruit juices (Apple, Pomegranate, Tomato, Guava, Mixed fruit, Mango, Litchi, Cranberry and Orange) & two vegetable pastes (Ginger and Ginger-garlic). Most of the pesticides were found below the tolerance limit i.e. 0.01 to 1.0 mg/kg, as per Food Safety and Standard Authority of India (FSSAI). Some pesticides like Chlorpyrifos in orange juice (1.08 mg/kg) & Deltamethrin (1.28 mg/kg) in ginger garlic were detected above the permissible limit of FSSAI
