Classification and Detection of Adulteration in Olive Oil Using Improved Gaussian Mixture Model and Regression by Artificial Bee Colony Algorithm

Chemical Engineering Transactions, 2016
Gaussian mixture model (GMM) and Gaussian mixture regression (GMR) can be used to detect adulteration in extra virgin olive oil. The estimate of the GMM parameters is commonly obtained from the expectation- maximization (EM) algorithm.

Leptin–cholesterol crosstalk in pregnancy: Mechanistic implications for placental function and cardiometabolic programming

Experimental Physiology, EarlyView.
Abstract Pregnancy requires the coordinated maternal reorganization of lipid and endocrine pathways to sustain fetal growth and anticipate neonatal nutrition. Leptin, produced by adipose tissue and the placenta, acts as an integrative signal linking maternal energy status with trophoblast function and vascular adaptation, while cholesterol provides ...

Molecular dynamics simulations of oleuropein diffusion in chitosan‐based nanoparticles

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 10, Page 2000-2010, October 2026.
Abstract BACKGROUND This study explores the diffusion mechanisms of oleuropein (OLE), a promising polyphenolic compound, within chitosan‐based nanoparticles using molecular dynamics simulations. Chitosan nanoparticles serve as drug delivery carriers, leveraging biocompatibility and tunable release properties influenced by environmental factors such as ...

Optimized Stacking Ensemble Machine Learning for Nondestructive Toxicological Risk Assessment of Fish Meat Using Hyperspectral Imaging

Journal of Food Safety, Volume 46, Issue 5, October 2026.
Hyperspectral imaging and an optimized stacking ensemble learning model are developed for rapid, nondestructive toxicological assessment of fish meat. This framework integrated multiple machine learning classifiers to accurately distinguish toxicologically contaminated fish from fresh samples using both reduced (25‐band) and full (224‐band) spectral ...

Comparative Study of Free and Total Fatty Acids of Spreadable Cheeses by Mass Spectrometry Methods

ChemFoodChem, Volume 2, Issue 3, September 2026.
This study focuses on the determination of FFAs in spreadable cheeses and alternatives using a fast Liquid Chromatography‐High Resolution Mass Spectrometry method. A Gas Chromatography‐Mass Spectrometry method was used to determine the composition (%) of total FAs in the same samples.
