Can olive oil be used for frying? We debunk four myths about this wonder oil
Whether making the heart healthy or regulating sugar levels or bringing with itself vitamins and antioxidants, olive oil is an ideal companion for all who wish to lead a healthy life. Recent studies say it can also help in preventing brain cancer and reduce cholesterol levels. But due to a lack of precise knowledge about this oil, some are reluctant to make it part of their daily lives. This is, to some extent, a result of all the crazy marketing out there: Peruse the olive oils in a typical grocery store and you’ll be greeted by all kinds of terminology.
Some of it is confusing — like “pure” and “extra-virgin” — which is better? Other terms are just pointless — “cold-pressed”, for example, doesn’t really mean much. Basically, all extra-virgin olive oil is cold-pressed. So it’s time we debunk some of the myths about this beneficial Mediterranean favourite.
Myth #1: If olive oil gets cloudy or solidifies in the refrigerator, it is 100% authentic and of high quality.
Fact: There is no home test to check for olive oil authenticity. Some oils get cloudy in the refrigerator and some don’t. Quality is best checked through taste and smell — authenticity is best-tested in a properly-equipped lab.
Myth #2: A very green colour indicates high quality olive oil.
Fact: Colour is not an indicator of the oil’s quality. Quality olive oil isn’t a generic product. Factors like olive variety, growing conditions and country of origin create variability in oil colour — from pale yellow to dark green — and how fast the oil will cloud or solidify in the refrigerator.
Myth #3: Heat diminishes olive oil’s health benefits; so it is best to use extra virgin olive oil “raw” or straight from the bottle.
Fact: Flavour may change when heated, but the health benefits remain. You can cook with all types of olive oil without losing health benefits because their smoking point is higher than most other cooking oils.
Myth #4: Olive oil cannot be used for cooking, frying and sautéing.
Fact: You can cook on high heat with olive oil. Here, the answer lies in understanding the various grades of olive oil. In India, one can most certainly find three grades of olive oil — extra virgin, classic/pure and extra light and, lastly, pomace, which is a chemically extracted variant of olive oil.
The difference lies in the taste, aroma and smoking point. Extra virgin olive oil has a strong flavour of olives and low smoking point as it is obtained from cold pressing. Pure olive oil is obtained from refining olive oil, so its smoking point is high but has the flavour of olives, so it can be heated and used for cooking pizzas, pastas, sautéing vegetables et al. Extra light has neutral/no flavour of olives and be used for everyday cooking/frying in Indian kitchens.
