Evolution of Virgin Olive Oil during Long-term Storage

Monitoring endogenous enzymes during olive fruit ripening and storage: correlation with virgin olive oil phenolic profiles.

The ability of olive endogenous enzymes β-glucosidase, polyphenol oxidase (PPO) and peroxidase (POX), to determine the phenolic profile of virgin olive oil was investigated. Olives used for oil production were stored for one month at 20 °C and 4 °C and their phenolic content and enzymatic activities were compared to those of ripening olive fruits. Phenolic and volatile profiles of the correspon...

Virgin olive oil and nutrition

Numerous medical studies (a study in seven countries, Monika study, Dart studies, etc. ) have shown that olive oil is one of the most important ingredient of "Mediterranean diet" associated with a reduction in cardiovascular disease and certain types of cancerous diseases. Nutritional and health value of virgin olive oil is attributed to the large proportion of monounsaturated fatty acids (main...

Nutrigenomics and Atherosclerosis: The Postprandial and Long-Term Effects of Virgin Olive Oil Ingestion

Epidemiological studies over the past 50 years have revealed numerous risk factors for atherosclerosis. They can be grouped into factors with an important genetic component and environmental factors, particularly diet, which is one of the major, constant environmental factors to which our genes are expose through life. When a gene is activated, or expressed, functionally distinct proteins are p...

Sensory Analysis of Virgin Olive Oil

Extra virgin olive oil and oleic acid

For many decades, researchers have investigated the relationships between health status and consumption of extra virgin olive oil. Extra virgin olive oil (and oleic acid) is considered important for the prevention of coronary heart disease. While the biomolecular aspects involving G protein need further research, oleic acid levels in platelets may be a discriminating factor, together with linol...
