Demystifying Olive Oil

Olive Oil has been produced for thousands of years. Originally, olive oil was used as lampante or lamp oil. Production was largely centralized to the Mediterranean, Asia Minor, and North African regions respectively. Today, however, Olive Oil production occurs in a number of countries across the globe, from Italy, Spain to Chile, Australia, Uruguay, and even a small little grove in British Columbia. 

When it comes to good quality olive oil, there are a few basic elements to keep in mind. Most consumers are familiar with ‘Extra Virgin’ as an oleic designation, however this is a slightly outdated term.  In fact, the terminology of ‘Extra Virgin’ was coined by the Romans to stop the practise of throwing hot water onto the olives before, and during crushing. The process of throwing hot water on the olives meant that more fat (and therefore olive oil) could be extracted, but the quality of the oil was significantly diminished as a result of the higher temperatures. As the Romans were quite particular about their oil, they enacted these types of measures to better control the quality of Olive Oil being produced at the time. 

Today, consumers should look for ‘Cold Pressed’ ,Olive Oil, meaning that as the olives are hammer crushed, milaxxed and separated, the temperature of the fruit and oil does not exceed 28 degrees celsius during production. The ‘Extra Virgin’ designation today means that Olive Oil must fall within specific chemical parameters, and must not have any taste faults. In order for an oil to be considered truly ‘Extra Virgin’, olive oil must possess an equally balanced taste profile of fruitiness, pungency and bitterness. Olive Oil should be tested at the time of crush by an independent third party laboratory, with a specific focus on the levels of Free Fatty Acids (quality of fruit at the time of crush), Peroxides (the level of post-production oxidization in the olive oil), and finally Polyphenols (naturally occurring anti-oxidants).

Independent tests from The University of California Davis have shown that up to 75% of olive oil on store shelves is expired, rancid, or blended with other flavourless and odourless nut and seed oils. So how do you safeguard yourself as a consumer? While Olive Oil may have both a complex history and chemical profile, buying olive oil doesn’t have to be quite so complicated. Consumers should look for date of production, not expiration, UV protected bottles, as direct sunlight is one of the biggest enemies of fresh olive oil, and most importantly, a trusted and certified purveyor of olive oil. Olive oil should, at the very least, have a slightly grassy and fruity taste. Fresh, quality olive oil has been positively associated with lowering cholesterol, blood pressure and even decreasing the risk of coronary disease. 

At its most simple, olive oil is simply a fresh pressed fruit oil. Add it to salads, marinades and even drizzled over popcorn! Eating healthy doesn’t have to be complicated, and good quality olive oil is a delicious way to add flavour and nutrition. Keep an eye out for freshness and fruitiness, and you’ll find that olive oil can easily become a flavourful staple in any kitchen.
