Due to the elevated cost of EVOO, adulteration with cheaper, poor-quality refined or edible oils has become a common practice for economic profit. The EVOO is purposely adulterated by blending four different edible oils with transparent or similar colors and similar refractive indices to replicate realistic adulteration scenarios. An in-house-built SPRE setup was used to conduct the experiments using a reusable bimetallic Ag-Au SPR sensor chip. The quantification limit for EVOO adulteration was successfully obtained at a low level of 5% (v/v) at room temperature. This optical technique has strength in its convenience, simple instrumentation, ease of sample preparation, minimal solvent usage, non-destructive nature, and rapid real-time analysis. We believe that our experimental outcomes make a valuable contribution to the field, addressing the critical need for reliable methods to ensure the authenticity and quality of EVOO.</p></div>","PeriodicalId":561,"journal":{"name":"Food Analytical Methods","volume":"18 3","pages":"442 - 458"},"PeriodicalIF":2.6,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is of great significance to accurately detect the quality and safety of milk powder to mitigate food safety problems. This paper presents a method for the determination of vanillin and ethyl vanillin in milk powder based on terahertz (THz) spectroscopy. Samples with varying concentration gradients of these two additives were prepared, and a terahertz time-domain spectrometer was used to collect spectral data from the samples in the 0.2 to 1.5 THz range. Seven spectral preprocessing algorithms were evaluated using the partial least squares (PLS) method, and it was found that the combination of multivariate scattering correction (MSC) and Savitzky-Golay (SG) smoothing preprocessing yielded the best results, significantly improving the accuracy of the test sets for both additives. Subsequently, nine quantitative detection methods were constructed by combining three dimensionality reduction algorithms (ant colony algorithm (ACO), competitive adaptive reweighted sampling (CARS), and successive projection algorithm (SPA)) with three regression models (support vector regression (SVR), long short-term memory (LSTM), and particle swarm optimization-back propagation (PSO-BP)). The results showed that the LSTM regression model, with dimensionality reduction performed by the CARS algorithm, performed best for detecting vanillin in milk powder, achieving a recognition rate of 94.49%. Compared to the other eight methods, this increased the recognition rate by 7.69%. Similarly, the LSTM regression model, combined with the SPA algorithm for dimensionality reduction, performed best for detecting ethyl vanillin in milk powder, reaching a recognition rate of 98.37%. This represented a 6.59% increase in recognition rate over the other eight methods, providing a novel technical approach for non-destructive testing and analysis of milk powder quality and safety.</p></div>","PeriodicalId":561,"journal":{"name":"Food Analytical Methods","volume":"18 3","pages":"398 - 415"},"PeriodicalIF":2.6,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current research deals with fabricating colorimetric films by admixing starch with silver nanoparticles (Cit-AgNPs) to detect fenobucarb in fruits. The resulting films present a homogeneous surface with a thickness depending on the amount of Cit-AgNPs incorporated. After coating with fenobucarb, the film could displace the negatively charged Ag surfaces. It is remarkable that metal nanoparticles, endowed with specific ligands, show huge promise for developing miniaturized colorimetric assays. This implies that they can detect a great range of molecules, allowing the determination of trace-level target analytes by discernible visible color changes perceivable through the naked eye. This has been successfully realized through surface plasmon resonance localized principles and aggregation of nanoparticle self-assembly, enhancing plasmonic Ag from the original transition of yellow to dark grey-brown hue. In the proposed sensor methodology, the linear range is 0.005 to 500 µM, with corresponding values in the limit of detection and quantification at 8.86 µM and 29.53 µM, respectively. The present investigation is a paradigm of reporting facile, rapid, and low-cost approaches to determine fenobucarb in food commodities and further evaluates a novel approach to food safety.
