This study proposes a machine learning model that integrates analytical measurements, data simulations, and classification techniques to detect adulteration of CO with refined sunflower oil (SO) and determine the detectable limit of adulteration without measuring a huge number of different mixtures. First, pure CO and SO samples were analyzed for their fatty acid, triacylglycerol, and tocochromanol content using HPLC or GC. The resulting oil composition data served as the foundation for further simulations. Monte Carlo (MC) simulations outperformed Conditional Tabular Generative Adversarial Networks (CTGAN) in simulating realistic oil compositions, with MC yielding lower Kullback-Leibler Divergence values compared to CTGAN. The MC-simulated data were then used to simulate larger datasets, a critical step for training and testing two classification models: Random Forest (RF) and Neural Networks (NN), as robust training cannot be achieved with small sample sizes. Both models achieved good classification accuracies, with RF achieving higher accuracy than NN, reaching 94% on simulated datasets and 90% on real-world samples with detectable adulteration levels as low as 1%. RF also offers better interpretability and is computational less demanding as compared to NN which makes it advantageous for authenticity verification in this study. Therefore, combining MC simulation with RF as a robust method for detecting CO adulteration is proposed. The proposed method, coded in Python and available as open-source, offers a flexible framework for continuous adaptation with new data.</div></div>","PeriodicalId":10939,"journal":{"name":"Current Research in Food Science","volume":"10 ","pages":"Article 100986"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted an <em>in vivo</em> study to evaluate the effects of citrus pectin on biomarkers of metabolic syndrome (MtS), including lipid profile, hypertension, and adipose tissue. Supplementing a high-fat diet (60% energy from fat) with 20% pectin for 4 weeks significantly reduced body weight and fat accumulation, improved insulin resistance, and decreased circulating leptin levels, demonstrating a beneficial effect on MtS. Pectin exhibited excellent viscosity, emulsifying properties, and water-holding capacity, forming a viscous gel in the gastrointestinal tract. This gel delays gastric emptying, enhances satiety, and reduces food and calorie intake, leading to lower weight gain in rats fed pectin. Its viscosity also interferes with lipase activity, lipid hydrolysis, and absorption, while its oil-holding capacity may help prevent lipid absorption. The presence of galactose in pectin's structure showed potential for improving insulin resistance. Furthermore, both degree of esterification (DE) and pH influence pectin's functionality. At acidic pH levels, such as those found in the stomach and duodenum, high methoxyl pectin (HMP) retains fats and bile salts more effectively, contributing to better cholesterol regulation. These effects, combined with the antioxidant properties of pectin, helped reverse arterial hypertension associated with MtS.

Recent studies have highlighted the therapeutic potential of bovine colostrum-derived extracellular vesicles (BCEVs) in modulating gut microbiota and enhancing gut barrier function, but their effects on NASH remain largely unexplored. To investigate the potential protective effects of BCEVs against NASH, 8-wk-old mice were fed a NASH-inducing diet for 3 wks while concurrently receiving oral BCEV administration. BCEV treatment markedly ameliorated hepatic steatosis, fibrosis, and inflammation. Transcriptomic analyses demonstrated a notable reduction in lipid metabolism, bacterial response, and inflammatory pathways in the intestine, as well as reduced expression of inflammation- and fibrosis-related pathways in the liver. Gut microbiota profiling revealed an increased abundance of <em>Akkermansia</em>, accompanied by enhanced cholesterol excretion. Furthermore, BCEV treatment promoted the production of tight junction proteins and mucin in the gut, reinforcing intestinal barrier integrity. These findings suggest that BCEVs promote the proliferation of <em>Akkermansia</em>, which in turn prevents endotoxin translocation to the liver. This reduction in endotoxin leakage alleviates hepatic inflammation and fibrosis.
