Lycium barbarum L., also known as goji berry, is popular in China and across the world as both a food and a medicine. The pervasive use of chemical pesticides has led to widespread contamination of raw goji berries, although the impacts of pesticide contamination on goji berry-derived products have not yet been thoroughly characterized.

This study examined the distribution of 37 pesticide residues in different cereal grains (rye, wheat, oat, and barley) and their fractions, including flour, bran, and feed bran. The grains used in the study were sprayed in the field before processing to provide a more accurate representation of the fate of pesticide residues in these fractions. Pesticides were extracted using the QuEChERS method and analyzed by GC-MS/MS and LC-MS/MS.

The prevalence of pesticide usage has brought the matter of pesticide residues to the forefront, necessitating the development of effective detection methods as a crucial step towards addressing this issue. This study presents a novel approach for detecting pesticide residues in vegetables using glass slide-formula-ion mobility spectrometry (IMS). The approach enables swift analysis of 36 different pesticides across three vegetable species with glass slides.

The presence of pesticide residues in vegetables is a worldwide issue regarding food safety. This study explores the efficacy of a novel advanced oxidation process (AOP), namely the coupled ultrasonic-ozonation (US/O3) process, for removing six commonly found pesticides from vegetables.

Population growth, international market expansion, and climate change have caused changes in agricultural practices, including increased use of phytosanitary products to control pests and diseases in food production. The European Union aims to achieve sustainable and high-quality food, with the priority of reducing pesticide use.

Quality and safety issues arising from herbicide residues in fishery products are a growing concern. In order to ensure the edible safety of fishery products, a comprehensive assessment of multi-class herbicide residues should be conducted. Hence a modified QuEChERS approach was explored and validated using UPLC-Q-Tof-MS/MS for rapid screening and quantification of 158 herbicide residues in fishery products.

A liquid chromatography-high resolution mass spectrometry (LC-HRMS) method for screening, quantification and identification of veterinary drugs (antibiotics, nonsteroidal anti-inflammatory drugs, anthelmintics, coccidiostatics and tranquilizers) and pesticide residues was validated in pig (porcine) muscle.

This study was carried out to detect pesticide residues in tropical fruits. QuEChERS method was validated to determine 301 different pesticides in high water content commodities and high acid content commodities by liquid chromatography-tandem mass spectrometry (LC–MS/MS) and gas chromatography-mass spectrometry (GC-MS). Matrix effects were determined for all pesticides in banana, blueberry, lime, mango, and pineapple.

In the present study, the effects of intermittent ozone (IO3) application combined with low dose fungicide and high-dose dissolved ozone in water on storage life and quality of orange cv. Washington Navel were investigated.

The aims of this study were to: i) analyze the prevalence and concentration of pesticides belonging to 4 major classes, namely organochlorines, organophosphates, carbamates and pyrethroids in chicken meat, liver and kidney; ii) evaluate the impact of boiling, frying and freezing on pesticide levels in chicken meat, and iii) estimate the dietary exposure to pesticide residues in chicken meat and conduct a risk assessment.

As a first-time study, the thermal storage stabilities of pesticides (bifenthrin, carbofuran, diazinon, methomyl, triflumuron, triadimenol, triazophos, and thiabendazole) in banana homogenate were investigated. Pesticides-spiked banana samples were stored at −20 °C (T1), 4 °C (T2), 25 °C (T3), and 40 °C (T4) and the residues were observed from day 0 to day 84.

The goal of the present study was to estimate the distribution and migration of eleven systemic and non-systemic pesticides between the skin and the pulp of apples. Additionally, the behaviour of acetamiprid, boscalid, bupirimate, cyprodinil, flonicamid, fluopyram, pirimicarb, pyrimethanil, thiacloprid, deltamethrin, and fludioxonil in two apple varieties during four thermal processes ranging between −40 °C and 150 °C was discussed.

In 2004, the Food Code of Korea adopted a multi-class multi-residue pesticide analysis method, which employed liquid–liquid extraction (LLE) and solid-phase extraction for sample purification. After several modifications, the LLE stage was replaced by the QuEChERS method in October 2021. Thus, in the current study a comparison was carried out between the new QuEChERS method and the conventional LLE method for the simultaneous analysis of multiple pesticide residues.

An ultrasound-assisted acetonitrile extraction method was applied for the determination of 43 pesticide residues in intact grape berries (Vitis Vinifera L.) by liquid chromatography-tandem mass spectrometry (LC–MS/MS). The results showed that ultrasound-assisted extraction from intact grape berries exhibited better efficiency than extraction from homogenized grape berries.

Vegetables and fruits may contain pesticides, leading to several health complications after long-term exposure. The food byproducts of soybean and camellia seed cake contain abundant saponins but are poorly utilized. This study aimed to investigate the capacity of soybean byproduct-extracted saponins (SBE) and camellia seed cake-extracted saponins (CSE) to remove pesticide residues in fruits and vegetables.

The present study sought to investigate the levels of multi-pesticide residues in highly consumed edible fungi in China's western regions. A total of 354 edible fungi samples were collected from the local markets, and the concentrations of 53 pesticides in these samples were determined through high performance liquid chromatography mass spectrometer (HPLC/MS/MS). Carbendazim, acephate, procymidone, prochloraz, aldicarb sulfone,etc.
