The modified electrode was characterized using scanning electron microscopy, electrochemical impedance spectroscopy, and cyclic voltammetry. The electrode surface area of the Pd-Cu/SPGE is about two times larger than that of the SPGE. Differential pulse voltammetry was used to determine the amaranth. The chromatographic method was preferred for the reference method. At the optimal parameters, the anodic peak current of amaranth was found to be linearly dependent on its concentrations ranging from 0.002 to 15.00 µM. The detection limit was 0.5 nM (S/<i>N</i> = 3). For the analysis of amaranth, 101.16–104.33% of recovery percentage was obtained. This highly selective and sensitive electrode supplied the fast determination of amaranth in real samples.

Roasting processes on oil content gave positive results, and the sample that provides the highest content (48.4%) is the sample that was roasted for 7 min in hot air.

One method of achieving standardization is through chemical fingerprinting. Among various techniques, colorimetric sensor arrays are deemed a reliable method for the quality control and diagnosis of medicinal plants. Unlike conventional methods such as DNA barcoding and spectroscopy, chemical fingerprinting offers a different analysis of the plant’s unique chemical patterns. Colorimetric sensor arrays were chosen for their cost-effectiveness, ease of use, and rapid results. The objective of this study was to devise an effective method for the classification of ten different commercial brands of thyme and to compare them with three reference original thymes using a colorimetric sensor array technique coupled with mathematical data analysis methods. The findings indicated that colorimetric sensor arrays could effectively represent noticeable color changes between different essential oil samples based on Color Difference Maps (CDMs). The subsequent application of multivariate pattern recognition methods improved the discrimination ability between the samples. Principal Component Analysis (PCA) revealed the discrimination of three classes of the samples with 93% of the total variance, highlighting the distinct separation between different thyme origins. Hierarchical Cluster Analysis (HCA) elucidated the similarity of the studied commercial samples to the reference samples of thyme essential oil, demonstrating clear grouping patterns. Furthermore, Partial Least Squares Discriminant Analysis (PLS-DA) indicated that the majority of commercial samples were as similar as the <i>thymus vulgaris</i> samples, with fitting and validation accuracy of 95% and 91%, respectively. This analysis effectively discriminated the commercial thyme essential oil samples, highlighting their notable similarities to specific reference samples and clarifying the alignment or deviation from different reference standards. Lastly, Linear Discriminant Analysis (LDA) confirmed previous results and differentiated the <i>Thymus</i> samples from <i>zataria multiflora</i>, with 100% fitting and 91% cross-validation accuracy. These methods together provided a comprehensive analysis, each contributing unique insights into the classification and potential standardization of thyme quality detection. Among the used sensing elements, 4 top sensor elements were identified using the factor loadings for the first three PCs of PCA analysis and discrimination ability. While this study primarily focuses on classification, it lays a strong foundation for future standardization efforts in quality control of thyme.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":631,"journal":{"name":"Journal of Food Measurement and Characterization","volume":"19 1","pages":"12 - 25"},"PeriodicalIF":2.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941131","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 tensile strength, Young’s modulus, elongation at breaks, and water vapor permeability of TG nanofibrous mats were in the range of 3.77–4.54 MPa, 39.53–68.64 MPa, 7.75-10.33%, and 6.25–14.12 × 10<sup>‾5</sup> g mm/m² h Pa, respectively. The lag phases of the peroxide value, <i>p</i>-anisidine value, and acid value for both treated butterfat samples with TG + LPE 1% and TG + LPE 3% nanofiber mats were determined to be 20 days, suggesting that the developed nanofiber mats can be successfully applied as antioxidant packaging materials for retarding the oxidation changes of fresh butterfat in the food industries.</p></div>","PeriodicalId":631,"journal":{"name":"Journal of Food Measurement and Characterization","volume":"19 1","pages":"76 - 88"},"PeriodicalIF":2.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941138","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}
