Answer 3

oil is a natural preservative that prevents spoilage by isolating the food from air, providing a seal that can delay oxidation and prevent moould occurring. Foods stored at room temperature require cooking beforehand (boiling in salted water or vinegar solutions) to preserve the food safely. In addition: • Vegetables packed in oil require care in preparation. They should be ripe and blemish free. • After washing the vegetables, make sure they are dry. • Cook vegetables in stainless steel (or non-reactive pans), since often vinegar is used in the preparation. • Make sure your tools and containers are clean and dry. • Use glass containers for storage with lids that close tightly. • Place your food in the containers until full and then completely cover with extra virgin olive oil. • Make sure none of the food is protruding above the oil. • Add olive oil to form a seal. • Cover tightly and store.

Answer 4

Air is the enemy of food. My guess is that the oil surrounds the food and prevents air from touching it, thereby preserving it.

Answer 5

You can't. Vegetable oil spoils.
