“…Pesticide residue levels during processing can be influenced by thermal degradation, evaporation, and co-distillation (blanching, steaming and boiling), dissolving (water or solvents washing), mechanical removal (peeling of vegetable skin) hydrolysis, photolysis, volatilization, and changes in pesticide residue levels due to weight changes [ 15 , 16 , 17 , 18 , 19 ]. Moreover, different LC-MS/MS or GC-MS/MS multiresidue methods for pesticide residue analysis of tomatoes [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ] and their amount after household processing, concerning washing and peeling [ 28 , 29 , 30 , 31 , 32 , 33 ], are reported in the literature. Kwon et al reported both a decrease of non-systemic pesticides by washing and peeling processes and an increase of some systemic pesticide residues in household processed tomatoes due to tomatoe water evaporation during the boiling process [ 34 ].…”

Pesticides are broadly used to improve food safety, although they can lead to adverse health effects on consumers. Various food processing approaches, at the industrial or domestic level, have been found to highly reduce the amount of pesticide residues in most food materials. In this work, samples of raw tomatoes were collected directly from the field and processed at the industrial level to produce purée, triple concentrated paste, fine pulp, and diced tomatoes. A multiresidue method based on a modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged e Safe) sample preparation, followed by liquid chromatography-tandem mass spectrometry analysis (LC-MS/MS) for the assessment of 116 pesticides residues, was used. The analytical method has been validated according to SANTE indications. The recovery yields ranged from 75.5% to 115.3%, repeatability (RSDr) ranged from 3.4% to 18.3%, while reproducibility (RSDwR) ranged from 5.4% to 19.8%. The limit of quantifications (LOQs) ranged from 2.35 µg kg−1 for benthiavalicarb to 6.49 µg kg−1 for allethrin. A total of 159 raw tomato samples were collected from the field. The analysis showed the presence of 46 pesticides with azoxystrobin and chlorantraniliprole the most represented. On the other hand, all industrially processed samples showed values ≤ LOD, confirming that post-harvest processes can lead to a decrease in pesticide residues from agricultural commodities.

“…Insecticides belonging to these chemical groups have been found to have be used on tomato crops by Sudanese farmers [6]. To evaluate food quality and to avoid risks to human health, governments and international organizations regulate the use of pesticides by setting the maximum residue levels (MRLs) in foods [7,8]. The low level of some MRLs has led to research to improve the limits of detection of key pesticides, using rapidly evolving analytical methods for their analysis.…”

Abstract-A total of 9 fresh tomato samples were collected from domestic markets in Khartoum State, Sudan and analyzed for the presence of seven pesticide residues. Sample collection and preparation were carried out using standard procedures.The concentrations of pesticide residues were determined by gas chromatography equipped with a flame ionization detector (GC-FID) after extraction with acetone in presence of dichloromethane, and cleanup on solid phase extraction cartridges. Recovery studies were performed at 0.5 mg kg-1 of each pesticide. Levels recovery obtained ranged between 67.5-97.2%. The limits of detection of the method ranged between 0.00122 and 0.00433 mg kg-1for different pesticides studied. Out of nine tomato fruit samples, eight were contaminated with one or more of the pesticides. The highest concentration of a pesticide residue was 13.88 mg kg -1 of beta endosulfan from Sample 2 collected from the Omdurman central market. The residue values were higher than the maximum residue levels (FAO/WHO, 2009) for all measured pesticides except deltamethrin.

Insecticide’s Disappearance after Field Treatment and during Processing into Byproducts

Insecticides - Impact and Benefits of Its Use for Humanity

View full text Add to dashboard Cite

Insecticide\'s disappearance after field treatments could be ascribed to different factors such as sunlight photodegradation, dilution effect due to fruit growth, co-distillation during fruit respiration and evaporation. Moreover, the epicuticular waxes could speed or slow down the degradation rate, and the cultivation in an open field or greenhouses could affect the residues dramatically. After harvest, the processing techniques to produce byproducts deeply influence insecticide residues. For example, fruit drying, winemaking, the industrial processing of tomatoes to produce purée, triple-concentrated paste, fine pulp, diced, olive processing to obtain table olive and olive oil, and other industrial applications on fruits affect residues and their half-life time. The scope of this chapter is to highlight the major factors responsible for the disappearance of insecticides after treatment. Moreover, the chapter intends to review the influence of the industrial processes on insecticide behaviour when the raw material is transformed into its byproducts.
