Extra virgin olive oil: from composition to "molecular gastronomy"

Area of Science:

• Food Chemistry
• Nutritional Science
• Culinary Arts

Background:

• Extra virgin olive oil (EVOO) is a staple in Mediterranean diets, known for its health benefits.
• Its unique composition includes biophenolic compounds and antioxidants.
• EVOO's role in traditional cooking methods is widely recognized.

Purpose of the Study:

• To review recent findings on EVOO interactions with other food ingredients during cooking.
• To elucidate the molecular mechanisms behind EVOO's culinary and health properties.
• To explore EVOO's impact on the sensory and nutritional quality of Mediterranean foods.

Main Methods:

• Review of existing scientific literature on EVOO and food interactions.
• Analysis of chemical and physical changes during cooking processes.
• Examination of specific food preparations: tomato-oil, fish canning, marinated meats, roasting, and frying.

Main Results:

• EVOO provides antioxidant protection and flavor enhancement during cooking.
• Interactions occur between EVOO's biophenols and food components like water, proteins, and fatty acids.
• Cooking modifies EVOO's sensory attributes (bitterness, fruity notes) and nutritional value.

Conclusions:

• EVOO offers health benefits even when used in cooking, not just raw.
• Understanding EVOO's interactions is key to optimizing its use in traditional and modern cuisine.
• EVOO plays a significant role in the health and sensory profiles of Mediterranean dishes.
