In order to investigate the influence of fatty acid pattern and antioxidants other than vitamin E on lipid peroxidation and antioxidant levels of plasma very low density and low density lipoproteins (VLDL + LDL), the effects of three diets (equalized for vitamin E) containing soybean oil, olive oil, or an oleate-rich mixture of triglycerides (triolein) were studied in rats. A significantly lowe...
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...
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 ...
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...
BACKGROUND Virgin olive oils are richer in phenolic content than refined olive oil. Small, randomized, crossover, controlled trials on the antioxidant effect of phenolic compounds from real-life daily doses of olive oil in humans have yielded conflicting results. Little information is available on the effect of the phenolic compounds of olive oil on plasma lipid levels. No international study w...
The effects exerted by polyunsaturated fatty acids (PUFA) on immune system functions have been investigated in recent years. These studies have reported the important role that n-3 PUFA play in the diminution of incidence and severity of inflammatory disorders. Nevertheless, less attention has been paid to the action of monounsaturated fatty acids (MUFA) upon the immune system. The administrati...
Phenolic compounds have shown to inhibit LDL oxidation in vitro and ex vivo; however, they are hydrosoluble compounds while LDL is a lipoprotein. Analysis of phenolic compounds in LDLs by HPLC is necessary to demonstrate their binding capacity to lipoproteins. We developed and validated a solid phase extraction method (SPE) that allowed us the purification of LDL samples and their analysis by H...
in order to evaluate the effect of harvest time on fruit weight, oil content and fruit bearing in the next year in some cultivars of olive (conservalea, amygdalolia, karidolia, koroneiki, arbequina, zard and rouwghani), an experiment was performed as a split plot in time based on crd (completely randomized design) with three replications at olive research station (tarrom–zanjan) during 2013 and...
We investigated the effect of olive oil, rapeseed oil, and sunflower oil on blood lipids and lipoproteins including number and lipid composition of lipoprotein subclasses. Eighteen young, healthy men participated in a double-blinded randomized cross-over study (3-week intervention period) with 50 g of oil per 10 MJ incorporated into a constant diet. Plasma cholesterol, triacylglycerol, apolipop...
This paper reports experimental data and the thermodynamic modeling of the liquid-liquid equilibrium systems with triacylglycerols, free fatty acids (obtained from olive oil), ethanol and water. The experimental data were fitted using the UNIQUAC model, in which absolute deviation of 1.28 % and root mean square deviation of 2.10 % between experimental and calculated mass fraction of the compone...
