Article Abstract
Olive oil samples were obtained from six cultivars grown in different environments, and graded by chemical analyses as extra virgin (EVOOs). These were evaluated for flavors and off-flavors, and relative VOCs spectrum as determined by PTR-ToF-MS. A hierarchical clustering of Panel test data separated olive oil in three groups, one including the samples with perceived off-flavor (VOOs), regardless of cultivar and environment. The Pearson's correlation coefficients between the mass data from PTR-ToF-MS and the sensory characteristics perceived by the Panel test were determined. A mass-to-sensory attributes correlation index was calculated. A color-coded card was built up based on the intensities (ncps) of five selected protonated mass data that was able to distinguish EVOOs from VOOs olive oil samples.

Background: With the development of modern agriculture, neonicotinoid pesticides have been widely used due to their high efficiency and strong systemic properties. However, excessive use leads to the accumulation of residues in the food chain, threatening the ecosystem and human health. Pesticide residues are easily accumulated in oilseed crops and become concentrated during the edible oil refining process.

Vitamin D is critically important for sustainable human health, and the rising prevalence of deficiency-related diseases has increased interest in natural sources. This study explores the potential of epiphytic lichen-forming fungi, known for their unique metabolites, as a novel biosource of vitamin D for pharmaceutical and nutraceutical applications. Fourteen epiphytic lichen species were collected using a stratified sampling method from four mountainous forests in the Marmara Region of Türkiye.

Olive pomace (OLP) and stones (OLS) are key by-products of olive oil production, rich in lignocellulose and pectin, making them viable substrates for prebiotic oligosaccharide (OS) production. This study evaluated the chemical composition of OLP and OLS powders (OLPp and OLSp) and their potential for OS production through one-step fermentation using recombinant Bacillus subtilis 3610. Both substrates had comparable xylan and pectin levels, but OLSp showed greater potential, achieving a maximum total sugar yield of 60 ± 3 mg.

Background: Fertilization of plants with selenium (Se) can enhance their resistance to abiotic stresses and improve human health and nutrition. However, Se fertilization in olive trees remains underexplored. This study evaluated the effect of foliar sodium selenite fertilization on leaf Se content, oxidative stress, olive tree productivity, biofortification of extra virgin olive oils (EVOO), and their physicochemical and antioxidant attributes in two mature 'Arbequina' olive orchards.

Glyphosate (GLY) is the most widely used herbicide globally. Despite concerns regarding its potential adverse effects on human health and the environment, its use continues to grow each year. Following application, a substantial proportion of glyphosate infiltrates the soil, where it can degrade into transformation products such as aminomethylphosphonic acid (AMPA), which is much more persistent than the parent compound.
