“…Several types of dSPE in QuEChERS are generally adopted as cleanup procedures for robust and simple pesticide analysis. Green samples with a high amount of chlorophyll (e.g., lettuce, spinach ,or tea) are challenging in multipesticide analysis because the chlorophyll in the final extracts may cause chromatographic problems as well as increased GC maintenance cost. , To remove pigments such as chlorophyll, GCB sorbent has been used, ,− and, recently, ChloroFiltr was introduced for the same purpose. , In this study, using spinach (a representative green sample) extract with ACN with 0.1% formic acid, four different types of dSPE sorbents were investigated to compare their effectiveness in terms of removing coextractives from green matrices, chromatographic separation, and recoveries.…”

A multiresidue method for the simultaneous and rapid analysis of 360 pesticides in representative agricultural produce (brown rice, orange, spinach, and potato) was developed using a modified QuEChERS procedure combined with gas chromatography-tandem mass spectrometry (GC-MS/MS). Selected reaction monitoring transition parameters (e.g., collision energy, precursor and product ions) in MS/MS were optimized to achieve the best selectivity and sensitivity for a wide range of GC-amenable pesticides. A short (20 m) microbore (0.18 mm i.d.) column resulted in better signal-to-noise ratio with reduced analysis time than a conventional narrowbore column (30 m × 0.25 mm i.d.). The priming injection dramatically increased peak areas by masking effect on a new GC liner. The limit of quantitation was <0.01 mg/kg, and the correlation coefficients (r) of matrix-matched standards were >0.99 within the range of 0.0025-0.1 mg/kg. Acetonitrile with 0.1% formic acid without additional buffer salts was used for pesticide extraction, whereas only primary-secondary amine (PSA) was used for dispersive solid phase extraction (dSPE) cleanup, to achieve good recoveries for most of the target analytes. The recoveries ranged from 70 to 120% with relative standard deviations of ≤20% at 0.01 and 0.05 mg/kg spiking levels (n = 6) in all samples, indicating acceptable accuracy and precision of the method. Seventeen real samples from local markets were analyzed by using the optimized method, and 14 pesticides in 11 incurred samples were found at below the maximum residue limits.

Foodomics is playing an essential role and is increasingly becoming a relevant multi-omic platform able to deal with traditional and new food challenges such as food safety, quality, traceability and health-diet interaction. In this context, innovative and high-throughput omic studies combined with bioinformatic tools are being developed for rapid identification of pathogens and multi-residue determination of contaminants, for understanding the interaction of bioactive compounds from diet, as well as for guaranteeing authenticity, traceability and quality of food products. This chapter aims to provide the reader with a general overview of the different areas of research covered by Foodomics, through the revision of state-of-the-art research works dealing with the application of the Foodomic approach to different aspects of Food Science including food safety, quality, traceability and health-diet interaction.
