Journal of the Science of Food and Agriculture, Accepted Article. Background Studies have shown that the consumption of apples has a beneficial effect on cardiovascular diseases and some cancers, largely due to their micronutrient and phytoconstituent contents. Apple peel contains more polyphenols than the flesh but is also likely to contain pesticide residues.

Journal of the Science of Food and Agriculture, Volume 102, Issue 5, Page 1782-1811, 30 March 2022. Until now, there is no method available for analysis of pesticide residues in complex matrices like spices. Therefore, there is an urgent need to develop and validate a QuEChERS-based method for the estimation of 104 pesticides in cumin seed. Samples were spiked for 109 pesticides at concentrations of 0.1, 0.5 and 1.0 mg kg−1. Of these 104 pesticides were recovered.

Journal of the Science of Food and Agriculture, Accepted Article. BACKGROUND
Pesticide contamination in oil crops and processed products is an important food safety concern. The study was aimed to investigate the pesticide residue changes in peanut oil press processing and chips frying.

Background
Until now, there is no method available for analysis of pesticide residues in complex matrices like spices. Therefore it is urgent need to develop and validate a QuEChERS based method for estimation of 104 pesticides in cumin seed.

Variability of pesticide residues in food item plays a key role for the evaluation of consumer food safety. However, variability factors (VFs) derived from the large size fruit crops are still scarce. Therefore, the present work was aimed to quantify pesticide residues and to estimate VFs in large size fruit crops of mango and guava.

BACKGROUND Chlorpyrifos (CPF) is a broad‐spectrum organophosphorus pesticide widely used to control tea geometrid (Ectropis oblique) and tea green leafhoppers (Empoasca pirisuga Matumura) in tea trees. The major metabolite of CPF in water, plants and animals is 3,5,6‐trichloro‐2‐pyridinol (TCP), which is more toxic than CPF. However, dissipation pattern of CPF in tea is unknown.

Background Pymetrozine is a widely used pesticide. It is challenging‐to‐analyse and difficult to manage due to the large gap in its global maximum residue limits (MRLs) in tea. Therefore, development of a high‐efficiency detection method for the evaluation of the transfer of residual pymetrozine from tea plantations to tea cups is of prime significance.

BACKGROUND Pesticide residues in agricultural products and foods pose a serious threat to human health, therefore a simple, rapid and direct method is urgently needed for pesticide residue detection. In addition to completing the detection of acetamiprid in the cabbage extracting solution, the main target of this study was to establish an in‐situ surface enhanced Raman scattering (SERS) method, which could directly detect acetamiprid residue on cabbage leaf without extracting it out.

ABSTRACT Background Fruit and vegetable consumption has increased among masses due to their tremendous health benefits. However, recent studies have shown that contaminated products may serve as a vehicle for foodborne pathogens and harmful chemicals. Therefore, fresh vegetables must be decontaminated before consumption to ensure food safety.

BACKGROUND Bananas are vulnerable to disease and insect pests after producing fruit. In order to increase the yield and produce high‐quality fruit, the insecticides and fungicides are mixed and applied 2‐3 times on banana, then the fruit is bagging. Buprofezin, imidacloprid, difenoconazole, and pyraclostrobin are widely used on banana. However, there is a lack of research on the effect of fruit bagging on pesticide dissipation and residues on banana.

BACKGROUD To extend the storage time of postharvest cherry tomato, boscalid are often used. Pesticide residue has become an issue of food safety. This study was to investigate the spatial distribution of boscalid residue in cherry tomato fruits and to determine the effect of 24‐epibrassinolide (EBR) in promoting boscalid degradation. RESULTS Boscalid could quickly penetrate into cherry tomatoes, but mainly remained in the peel.

BACKGROUND Pesticides have been widely used to control pests on agricultural products in China, and large amounts of pesticide residues have caused a serious threat to human health. Thus, developing a high‐efficiency pesticide degradation method for fresh vegetables represents a great challenge. In this study, the effects of dielectric barrier discharge (DBD) plasma on the degradation of malathion and chlorpyrifos in aqueous solutions and on lettuces were investigated.

BACKGROUND Iprodione is considered to be an endocrine‐disturbing pesticide, which could harm consumers. The garlic crop has three edible parts: the garlic, the green garlic, and the garlic shoot, which correspond to different stages of its growth. In this study, iprodione residue dissipation and distribution in these three edible parts were investigated, and dietary risk was evaluated.

Background Pyraclostrobin and picoxystrobin are two representative pesticides of strobilurins used to treat cucumber downy mildew, which have raised issues of food safety and human health. A new formulation containing these two compounds is being prepared for marketing in China.

ABSTRACT Background Fluopyram is a pesticide widely used in tomato and cucumber crops cultivation to control fungal diseases that develop especially in environments with moderate temperatures and high humidity, such as in a greenhouse. The pathway of fluopyram dissipation has been monitored in cucumber and cherry tomato under greenhouse conditions.

BACKGROUND Pesticides are widely utilized worldwide to control undesirable life forms during the planting procedure in agriculture. But they can pollute the nature and jeopardize human wellbeing. Additionally, on account of high resistance and biological activity; pesticides are able to accumulate in living organs and lead to acute and long‐term negative effects along with toxicity.

BACKGROUND The use of pesticides during tea plant cultivation support agricultural production and prevents and controls pests, diseases, and weeds. It is of the utmost importance to balance pesticide application with tea quality, safety, and consumer health. The uptake of pesticides into plants may lead to the presence of residues that are hazardous to human health, especially for some foliar‐applied insecticides.

BACKGROUD Pesticides are widely used to control insect infestation and weeds in agriculture. However, concerns about the pesticide residues in agricultural products have been raised in recent years because of public interest in health and food quality and safety. Thus, rapid, convenient, and accurate analytical methods for the detection and quantification of pesticides are urgently required.

ABSTRACT BACKGROUND Cyromazine and acetamiprid are widely applied as pesticides in agriculture, causing increasing concerns about their residues in crops. In this study, cyromazine, acetamiprid and their mixture were applied to cowpea to investigate their degradation dynamics and perform a dietary risk assessment.

BACKGROUND Increased awareness of consumers on food safety promotes the development of rapid and sensitive detection techniques for pesticide residues. In this study, a new type of rapid detection card for organophosphorus (OPs) and carbamates (CMs) pesticide residues was developed by electrospinning.

Background A modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method was developed for the simultaneous determination of highly water‐soluble propamocarb and hydrophobic cymoxanil in potato tuber and tomato fruit. Residue behavior of the fungicides in open field or greenhouse were investigated for the safety evaluation of these two pesticides, and effect of the cultivation condition, fungicide exposure and fruit size of tomato on residue level were discussed. Results.
