High-field 31P NMR (202.2 MHz) spectroscopy was applied to the analysis of 59 samples from three grades of olive oils, 34 extra virgin olive oils from various regions of Greece, and from different olive varieties, namely, 13 samples of refined olive oils and 12 samples of lampante olive oils. Classification of the three grades of olive oils was achieved by two multivariate statistical methods a...

The effect of repeated consumption of virgin olive oil on endogenous phenolic metabolites of fasting plasma is unknown. For this reason, we hypothesized that regular long-term virgin olive oil intake could have an indirect protection effect on the endogenous phenols. Thus, the aim of the study was to determine the phenolic profile of human plasma in a fasting state of long-term regular virgin o...

26 This narrative review compares evidence from experimental, epidemiological and 27 clinical studies of the health benefits of rapeseed (Canola) oil and olive oil in order to 28 assess if rapeseed oil is suitable as a sustainable alternative to olive oil as part of a 29 Mediterranean-style diet in countries where olive trees do not grow. From 30 epidemiological studies, the evidence for cardio...

The present work has been carried out to ascertain the influence of different processing systems employed in olive process on the chemical composition, quality and stability of three Chemlali olive oils. Among these oils, two were classified as extra-virgin olive oils and the third named repassed olive oil was classified as an ordinary virgin olive oil. The analysis of the effect of the process...

Olive (Olea europaea), whose importance is mainly due to nutritional and health features, is one of the most economically significant oil-producing trees in the Mediterranean region. Unfortunately, the increasing market demand towards virgin olive oil could often result in its adulteration with less expensive oils, which is a serious problem for the public and quality control evaluators of virg...

Virgin olive oil is the juice from the olive drupe, a produce that usually features high 6 quality. However, virgin olive oils produced in different regions of the world suffer from 7 defects, most of them of sensory nature. The largest amount of olive oil in which some 8 organoleptic defect is present matches to the Virgin Olive Oil (VOO) class. The causes 9 leading to sensory defects in virgi...

Virgin olive oil, the main fat of the Mediterranean diet, is per se considered as a functional food-as stated by the European Food Safety Authority (EFSA)-due to its content in healthy compounds. The daily intake of endogenous bioactive phenolics from virgin olive oil is variable due to the influence of multiple agronomic and technological factors. Thus, a good strategy to ensure an optimal int...

BACKGROUND It is unknown whether individuals at high cardiovascular risk sustain a benefit in cardiovascular disease from increased olive oil consumption. The aim was to assess the association between total olive oil intake, its varieties (extra virgin and common olive oil) and the risk of cardiovascular disease and mortality in a Mediterranean population at high cardiovascular risk. METHODS ...

BACKGROUND & AIMS In this study we report the effects of sunflower, virgin olive and fish oils on the lipid profile and antioxidant defence system in liver mitochondria from rabbits with experimental atherosclerosis. METHOD An atherogenic control group were fed for 50 days on a diet containing 3% lard and 1.3% cholesterol. Four groups were fed for an additional period of 30 days with a diet e...

Due to its higher price, compared to other edible oils, control of adulteration of the olive oil is one of the main aspects to be evaluated in its quality control. Adulteration with hazelnut oil is one of the most difficult to be detected due to the great similarity existing in the composition of hazelnut and olive oils; both virgin olive oil and olive oil are subjected to that kind of adultera...
