Typical freshness detection methods widely used now show accurate result, but are destructive, time-consuming and costly, such as total viable count (TVC), total volatile basic - nitrogen (TVB-N), gas chromatography - mass spectrometry (GC-MS), and biogenic amines (BAs) testing. To address this issue, an oyster freshness detection method is proposed based on electronic nose (E-nose) technology combining with a novel freshness classification model named PriorBoost-CNN-LSTM. The relationship between E-nose sensor responses and typical physicochemical detection results was explored under varying temperature conditions and high related prior information of TVC, TVB-N, BAs with gas sensors were incorporated to the model to enhance the performance of E-nose system. This model is capable of predicting subtle freshness variations on an hourly basis under temperatures of 4 °C, 12 °C, 20 °C, and 28 °C, with accuracy rates increasing from 69.7 % to 81.2 % compared to the unboosted model.

Although the use of RhB is prohibited due to its highly toxic properties, it is used in different cosmetics and foods because of its low cost and broad availability. Therefore, appropriate analytical techniques are required to monitor such compounds. Since RhB is a predominantly apolar molecule, it can be extracted selectively and effectively by using materials with a dominant hydrophobic character in its isolation from the matrix environment. In this study, methyl-terminated polydimethylsiloxane (PDMS) grafted Fe<sub>3</sub>O<sub>4</sub> nanoparticles (PDMS-Fe<sub>3</sub>O<sub>4</sub> NPs) were synthesized as a superhydrophobic medium and used for magnetic solid phase extraction of RhB at trace level prior to it’s UV-Vis spectrophotometric analysis. The superhydrophobic PDMS- Fe<sub>3</sub>O<sub>4</sub> NPs exhibit selective attraction to RhB and repulsion from other compounds, thereby enhancing the accuracy of the analysis. Along with magnetic solid phase extraction, effects of pH, the quantity of adsorbent, the type and volume of eluent, the volume of the sample, and the optimization of the real sample were investigated. The limit of detection (LOD), limit of quantification (LOQ) and preconcentration factor (PF) values of the proposed magnetic solid-phase extraction MSPE method were calculated as 0.5 µg·L<sup>−1</sup>, 1.7 µg·L<sup>−1</sup> and 267, respectively. The MSPE method can be applied for various cosmetic and food samples for the sensitive and accurate determination of trace RhB with high recoveries that range from 86.4 % to 103.7 %.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"148 ","pages":"Article 108406"},"PeriodicalIF":4.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145265414","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}
