Herein, this work present a highly sensitive assaying study based on three-dimensional graphene/cerium oxide nanoparticle nanozyme for the detection of organophosphate pesticides (OPs) in vegetable. The detection mechanism is because OPs can inhibit the activity of alkaline phosphatase (ALP). Cerium oxide nanoparticles exhibited intrinsic biomimetic oxidase activity and catalyzed the oxidation of the colorless 3,3′,5,5′-tetramethylbenzidine (TMB) into blue oxidized oxTMB. Upon the introduction of ALP, L-ascorbic acid-2-phosphate can be dephosphorylated to ascorbic acid, which aroused the disintegration of cerium oxide nanoparticles into Ce ions. This disintegration weakened the enzyme-mimicking activity, thus impeding the oxidation of TMB. The absorbance at 652 nm exhibited a linear relationship with the concentration of phorate in the range of 0.15–50 μg/mL, generating a limit of detection of 0.13 μg/mL, Phorate recovery in the spiked samples for the absorption detection mode was 81.0 %–96.7 %. The relative standard deviations (RSD) of the absorption were in the range of 2.18 %–4.12 %. The results in terms of detecting pesticide residues collected from food samples via this method satisfactorily agree with those obtained via gas chromatography–mass spectrometry. This simple assay is therefore suitable for sensing pesticides in complex samples, especially in combination with other portable platforms.","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed significant variations in these factors among the varieties. The main component of cassava flour was total digestible starch, accounting for approximately 84.86 %, with low levels of crude fat and protein. Cassava flour showed low calcium, iron, and zinc levels, and a wide variation in phytates, potentially reducing their bioavailability. All the flour from the ten cassava varieties met safety limits for cyanide levels <10 mg/kg, with the Selele variety having the lowest cyanide. The starch analysis showed higher levels of Slowly Digestible Starch (41.1–53.0 %) and lower levels of Rapidly Digestible Starch (29.5–36.0 %). Cassava flour also showed significant levels of resistant starch ranging between 4.56 % and 7.23 %, supporting its beneficial impact on human health.

An analytical quality-by-design (QbD) approach was adopted to optimize the developed approach. A two-level full factorial design (2 FFD) was implemented to optimize how variable factors affected chromatographic responses. On a Hypersil BDS C18 column, the chromatographic separation was carried out using isocratic elution at 40.1 °C. The mobile phase consisted of methanol: potassium phosphate buffer containing 5.76 mM heptane sulphonate (9.05 mM; pH 3.32, 44.8:55.2 % v/v) pumped at a flow rate of 0.8 mL/min and an injection volume of 20.0 μL. In less than 7 min, the suggested method was able to separate the ternary mixture with a challenging ratio of 1: 15.6: 1 for amoxicillin, amprolium, and ethopabate, respectively. The calibration curves showed excellent linearity over the concentration ranges of 0.50–30.0, 0.30–30.0, and 0.05–20.0 μg/mL, respectively.

Furthermore, the proposed method was successfully applied to determine the studied drugs in their commercial formulations. Full validation was carried out according to ICHQ2 (R1) guidelines.
