Health benefits of lycopene from tomato products have been suggested to be related to its antioxidant activity. Dietary fat may influence the absorption and hence the plasma levels and antioxidant activity of lycopene. In the present study, we have compared the effect of consumption of tomato products with extra-virgin olive oil vs. tomato products plus sunflower oil on plasma lycopene and anti...

background:confirmation of olive oil authenticity and particularly virgin olive oil has a great importance. several advanced chemical and genetic analyses have been used to monitor especial components; however each has its limitations especially when detecting hazelnut-adulterated olive oil. objectives:the objective of this research is to assess the presence of trace amount of hazelnut oil in o...

Olive oil is concentrated in the Mediterranean basin countries. Since the olive oil industries are incriminated for a high quantity of pollution, it has become imperative to solve this problem by developing optimized systems for the treatment of olive oil wastes. This study proposes a solution to the problem. Burned olive waste ash is evaluated for using it as clay stabilizer. In a laboratory, ...

BACKGROUND Because olive oil is an important component of the Mediterranean diet, it is necessary to establish unequivocal identification of the major potential antioxidant phenolic compounds it contains. METHODS The major phenolic antioxidants in extra virgin olive oil were isolated and purified. Structural analysis was conducted using several spectroscopic techniques, including mass spectro...

Olive and rapeseed oil are both considered beneficial for lipid metabolism because of their high content of monounsaturated fatty acids. We compared postprandial lipid metabolism after test meals with these plant oils including hydrogenated plant oil as a reference. Subjects and Methods: Twenty normolipidemic subjects (age: 25.1±4.9 year, M±SEM, body mass index 21.5±0.6 kg/m) underwent three on...

BACKGROUND Liver disease is the major cause of serious health problem leading to morbidity and mortality worldwide and the problem has increased in search for hepatotherapeutic agents from plants. The present study was designed to compare the probable hepatoprotective activity of olive oil and N. sativa oil on CCl4 induced liver damage in male rats. METHODS Forty males of a new model of albin...

STUDY OBJECTIVES Colorectal cancer (CRC) is a common cancer in many western countries and is probably caused in part by dietary factors. Southern European countries have lower incidence rates of CRC than many other western countries. It was postulated that, because olive oil is thought to influence bile salt secretion patterns in rats, it may influence the occurrence of CRC. The purpose of this...

This study was conducted to evaluate the combined effect of high pressure (HP) with the addition of soy sauce and/or olive oil on the quality and safety of chicken breast meats. Samples were cut into 100 g pieces and 10% (w/w) of soy sauce (SS), 10% (w/w) of olive oil (OO), and a mixture of both 5% of soy sauce and 5% olive oil (w/w) (SO) were pressurized into meat with high pressure at 300 or ...
