Can olive oil be used as a preservative?

You can preserve certain foods in olive oil. Eggplant, roasted tomatoes, sundried tomatoes, roasted peppers, mushrooms, some cheeses, chilies and olives come to mind immediately. Short-term: top with a 1 inch thick layer of olive oil and a clean lid, and they will keep in your refrigerator for 3-4 months.

Long-term: Top the jars off with a thin layer of olive oil, leaving a good inch of head space. Date the jars and place them without lids into the freezer. Because liquid expands as it freezes, it is best to let the jars freeze without lids first to be sure that the jars to not crack.

When frozen, you can top with clean lids, and they will keep for up to one year. Long Term Shelf - Pack sterilized jars, leaving about 1 inch of head space. Add 1 teaspoon of lemon juice or red wine vinegar to your what ever you are canning and top off with extra virgin olive oil, leaving a final 1/2 -inch of head space.

The added lemon juice or vinegar increases the acidity to prevent the growth toxins or bacteria. Top with sterilized lids. Line the bottom of a large pot or canning kettle with a folded dishtowel.

Place your jars in the kettle on top of the dish towel at least ½ inch apart. Fill the pot with water until it covers the tops of the jars by at least one inch. Bring the pot of water to a low boil.

Adjust the heat to maintain a steady simmer and process the jars for 30 minutes. Carefully remove the jars with a jar lifter and place on a clean towel to cool completely without disturbing. Store on a cool, dry shelf for up to 1 year.

Thank you for that wonderful answer. I was wanting to know also if when I bake with it will it help to preserve what I bake or will baking ruin the preserving qualities of the olive oil? Sakubi 14 months ago .

I've come across it for preserving garlic buds; seen it in the grocery store.

Excellent answer Carla. Living in Spain I often see the vegetables you describe preserved in olive oil. Clay Douglass com/profiles/claydouglass.

No, oils become rancid with age. They do have a shelf life.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
