Abstract:
... Extra virgin olive oils (EVOO) are vulnerable to adulteration. Thus, a rapid and cost effective screening method is required to detect adulteration. This study develops a method for detecting EVOO adulterated with refined olive pomace oil (ROPO) based on polarity reversal method (PRM). A device is designed based on PRM to determine current of oil sample. Adulteration is detected according to the c ...

Abstract:
... The adulteration of extra virgin olive oil (EVOO) with low quality edible oils is a major problem in the industry leading to economic frauds as well as customers’ health issues. A number of techniques have been used in the recent years for the characterization of extra virgin olive oil adulteration. In the current work, the spectroscopic techniques of absorption and fluorescence in combination wit ...

Abstract:
... Extra virgin olive oil is often associated with anti-inflammatory and antioxidant properties. Its effects on inflammatory conditions such as ulcerative colitis (UC), however, have yet to be defined. As such, we aimed to conduct a systematic review and meta-analysis of studies investigating olive-based interventions in UC. A comprehensive database search for randomised controlled trials was perform ...

Abstract:
... The growing demand for extra virgin olive oil (EVOO), appreciated for its unique organoleptic properties and health benefits, has led to various fraudulent practices to maximize profits, including dilution with lower value edible oils. The adulterated oils would be of poor nutritional quality, more readily oxidized, and may contain unhealthy substances formed during processing. Nevertheless, the r ...

Abstract:
... There is scarce scientific information regarding the potential benefits of healthy lifestyles in patients with hidradenitis suppurativa (HS). The objective of this study is to explore the potential association between the adherence to a Mediterranean diet (MD), physical activity and HS severity. A cross-sectional study that included patients with HS was conducted. Disease severity was evaluated by ...

Abstract:
... This review sought to describe the role played by some components of the microbiota of extra virgin olive oil (EVOO), particularly yeasts, in structuring the physicochemical and sensorial quality of freshly produced olive oil. Yeasts can survive during the entire storage period of the product. To date, approximately 25 yeast species isolated from oil produced in more than six countries have been i ...

Abstract:
... Extra virgin olive oil is highly appreciated worldwide for its healthy and organoleptic properties. From the variety of compounds present in the oil, phenols stand out, not only for producing the bitter-pungent perception but also for their antioxidant properties, which contribute to human health protection. The addition of plants can change the phenolic profile due to a migration of plant antioxi ...

Abstract:
... Many patients with depression are reluctant to take psychiatric medications. Hence, complementary therapies such as nutritional considerations could be advantageous. The antidepressant potential of olive oil has been proved in observational studies. The effect of extra-virgin olive oil (EVOO) on depression symptoms and cortisol and brain-derived neurotrophic factor (BDNF) levels in patients with d ...
... Oleocanthal is a nutraceutical compound present in extra-virgin olive oil (EVOO), endowed with several health properties, such as anti-inflammatory, neuroprotective and anticancer effects. During the EVOO storage, oleocanthal can undergo oxidative processes that lead to the formation of oleocanthalic acid. The aim of this work was to develop a reproducible and efficient method for isolation and pu ...
... Extra virgin olive oil (EVOO) was gelled with 10% monoglycerides, (MG), rice wax (RW), γ-oryzanol, and β-sitosterol (PS), or ethylcellulose (EC). The oleogel structure and the stability of bioactive compounds were investigated during storage up to 120 days at 20, 30, and 40 °C.All samples were self-standing but presented different structures. PS produced the firmest gel, whereas EC caused the lowe ...

Abstract:
... The interest in the modulation of gut microbiota by polyphenols from olives and derived products is increasing. In this work, phenolic leaf extracts (PLE) were in vitro faecal fermented to evaluate the changes in phenolic profiles and the impact on microbiota, using a commercial extra-virgin olive oil (EVOO) as reference. The in vitro fermentation decreased oleuropein content in PLE, determining a ...

Abstract:
... Volatile compounds are responsible for the valued aroma of extra virgin olive oil (EVOO). Among them, it is worth emphasizing the relevance of C6 and C5 volatiles formed in the lipoxygenase pathway. These compounds are direct indicators of positive attributes such as fruity, sweet, green or ripeness. Here, we have analyzed the volatile profile of 193 EVOOs obtained in two consecutive seasons to ev ...

Abstract:
... Ligstroside, ligstroside aglycone, and oleocanthal are extra virgin olive oil (EVOO) bioactive phenols poorly represented in olive leaves. Semisynthetic pathways to achieve them, starting with largely available natural precursors, are proposed as alternative solution with respect to their low effective extraction or total synthesis. In the present work, we propose the first green chemocatalytic me ...

Abstract:
... Coratina monocultivar extra virgin olive oil (EVOO) is known for its level of bitterness, which, if too high, can cause consumer acceptance problems. The aim of this study was to modulate the bitter taste of freshly produced olive oil through endogenous enzymatic activity and microbiota during the decantation phase. The opalescent appearance of the newly produced EVOO was substantially reduced dur ...
