Summary: The growing demand for extra virgin olive oil (EVOO) has led to fraudulent practices that dilute the oil with lower value alternatives. Adulterated EVOO can be of poor nutritional quality and may contain unhealthy substances formed during processing. However, reliable markers and scientific methods are being developed to detect fraud and ensure the authenticity and traceability of EVOO.

Summary: A front-face fluorescence method was used to analyze the excitation-emission matrix (EEM) of various Italian mono-cultivar and mix-cultivar extra virgin olive oils. It was found that at least 3 excitation wavelengths are needed to obtain 5 variables explaining over 95% of the sample variance, leading to the identification of sensitive fingerprint characteristics of the EVOOs. A non-parametric fine k-NN classifier was determined to be the best model for classifying the cultivar and geographical origins of the EVOOs, showcasing the potential for multiple excitation fluorescence techniques in authentication.

Summary: This study presents an analytical procedure for measuring the Sr-87/Sr-86 isotopic ratio in olive oil and pomace using multicollector-inductively coupled mass spectrometry (MC-ICPMS). The developed method combines liquid-liquid extraction with an acid solution and degradation of organic residues in the extract by dry ashing and oxidation by H2O2 and HNO3. The results show that olive oil and pomace have an identical Sr-87/Sr-86 ratio, which can be used in geographical traceability studies of olive oil.

Summary: This study found that the addition of 5%, 10%, and 20% v/v sesame oil to olive oil can delay the oxidation process during deep frying, and increase the frying time of olive oil. Furthermore, replacing olive oil with sesame oil can reduce the rate of formation of secondary oxidation products. Extra virgin olive oil (EVOO) is more resistant to oxidation than regular olive oil, and the frying time increases when EVOO replaces olive oil.

Summary: This study established the correlations and relationships of nine traits of pistachio kernels. PCA, Bayesian Networks method, and Network Meta-Analysis were applied to evaluate the data. The results showed high similarity between pistachio varieties and the ability to separate them into four distinct groups. The comparison between varieties revealed significant similarity between the 'KERMAN' accession and the Tunisian genotype 'ELGUETAR'. The findings also demonstrated the interdependencies between morphological parameters and relationships between studied factors through heat maps.

Summary: This study aimed to investigate the influence of physical activity on DNA methylation changes of the RANKL promoter region and assess the effect of aerobic and strength training on RANKL DNA methylation in Tunisian-North African adults. The results showed that active adults had significantly higher methylation levels in the RANKL promoter region compared to sedentary adults. After the intervention, both the trained and untrained groups exhibited increased methylation levels in the RANKL promoter region. The trained group also showed improvements in various physical parameters.
