How is Olive Oil Made?

Olive oil is simply made by pressing fresh olives until the oil comes out. This can be done at home or on a larger scale for commercial production.

Pressing is the healthiest way to make olive oil. First the olives and their pits are ground up into a paste. Then they are pressed between plates exerting a high amount of pressure so that the oil can be extracted.

Pressed olive oil is superior to olive oils that have been produced through chemical and high heat extractions for four reasons.

  1. It’s more environmentally friendly.
  2. Cold pressed olive oil doesn’t get heated above 120 degrees which keeps the nutrients in tact. Heating oil above 120 degrees will damage it.
  3. There are a ton of nutrients in raw (cold pressed) olive oil including vitamin E, K and A.
  4. Storage: Cold pressed olive oil has a long shelf life because it has a lot of monounsaturated fatty acids called oleic acid which prevents olive oil from going rancid.

Olive Oil Brands to Avoid

There are a number of reasons to avoid the following olive oil brands because they’re overall quality is low. For example many of these companies dilute their olive oil with other types of oils like soybean oil. The oils that have been diluted often have flavor, fragrance and color added to them so that they can be passed off as pure olive oil.

Another reason to avoid these brands is because of the way they are produced. In the section above we discussed why cold pressing is the best way to extract oil from olives. These companies use high heat and chemicals to draw the olive oil out of the olives. These chemicals and heat denature the olive oil and can make them carcinogenic because the oil gets heated past it’s smoke point.

The simple truth is that you get what you pay for. Bargain olive oil is usually not the real deal. It is essential to purchase high quality oils. If you’re on a budget there are plenty of other areas where you can cut expenses without compromising your family’s health. For instance, instead of meat you can make lentils which are just as high in protein but cost pennies to make.

These are the five brands of olive oil I would Avoid:

  • Carapelli
  • Mezzetta
  • Mazola
  • Primadonna
  • Pompeian

How to Test The Quality of Olive Oil At Home

Does reading this article make you second guess the quality of the olive oil you have in your pantry. A lot of readers may be surprised to find their favorite brands of oil are on the avoid list.

You don’t have to guess whether or not the olive oil you have is of good quality or not, you can test it at home!

This is how to test olive oil at home:

Place the olive oil in the fridge over night. If the oil turns solid, then it’s pure olive oil, but if it remains in a liquid state it has been diluted with other kinds of oils.

Another indication that olive oil is good quality is if it is stored in a dark glass bottle or metal container. The dark color keeps light from hitting the oil because exposure to sunlight causes olive oil to go rancid.

Which Brands of Gluten Free Olive Oil Are the Best?

While all of the brands in my initial “gluten free olive oil brand” list are gluten free, upon closer inspection some are higher quality than others. Remember, just because an olive oil is labeled gluten free does not mean it’s pure olive oil. It also doesn’t necessarily mean that the olive oil was harvested through the cold press method.

In this section you’ll find a list of my favorite gluten free olive oil brands based on product quality and which brands best support over all health.
