Extra Virgin Truths: Debunking 7 Olive Oil Myths
Olive oil has been a staple in kitchens worldwide for centuries, prized for its flavor and health benefits. However, numerous myths surround this "liquid gold," often leading to confusion among consumers and home cooks. Let's separate fact from fiction and explore the truth behind these common olive oil misconceptions.
Contrary to popular belief, olive oil has a relatively high smoke point, making it suitable for most cooking methods. Extra virgin olive oil (EVOO) has a smoke point ranging from 176°C to 210°C, which is higher than many other common cooking oils. This means it can withstand the heat required for sautéing, roasting, and even some frying without breaking down or producing harmful compounds.
While it's true that heat can degrade some compounds in olive oil, research shows that many of its beneficial properties remain intact during cooking. A study published in the Journal of Agricultural and Food Chemistry found that olive oil retained most of its phenols and antioxidants even after being heated to 180°C for 36 hours. In fact, cooking with olive oil may even enhance the absorption of some nutrients from vegetables.
This myth likely stems from the misconception about olive oil's smoke point. In reality, olive oil can be used for deep frying, although it may not be the most economical choice. A study carried out by the University of Granada found that olive oil remained stable under deep-frying conditions and produced fewer harmful compounds compared to other vegetable oils.
The color of olive oil can range from golden to deep green, but this variation is not an indicator of quality. The color is influenced by factors such as olive variety, ripeness at harvest, and processing methods. Professional tasters use blue glasses to evaluate olive oil to avoid being influenced by color.
Unlike wine, olive oil does not improve with age. Fresh olive oil is best, as it contains the highest levels of beneficial compounds. Over time, olive oil can become rancid, losing its flavor and nutritional value. It's recommended to use olive oil within 12-18 months of its harvest date for optimal quality.
The refrigeration test, where genuine olive oil is supposed to solidify in the fridge, is not a reliable indicator of quality or authenticity. Different olive oils may react differently to cold temperatures based on their fatty acid composition, which can vary naturally. The best way to ensure quality is to purchase from reputable sources and look for certifications.
"Light" olive oil does not refer to its caloric content. All olive oils, regardless of their label, contain about 120 calories per tablespoon. The term "light" typically refers to the oil's flavor profile or color, often indicating that it has been refined.
Myth #1: Olive Oil Has a Low Smoke Point and Isn’t Suitable for Cooking
Contrary to popular belief, olive oil has a relatively high smoke point, making it suitable for most cooking methods. Extra virgin olive oil (EVOO) has a smoke point ranging from 176°C to 210°C, which is higher than many other common cooking oils. This means it can withstand the heat required for sautéing, roasting, and even some frying without breaking down or producing harmful compounds.
Myth #2: Heating Olive Oil Destroys Its Health Benefits
While it's true that heat can degrade some compounds in olive oil, research shows that many of its beneficial properties remain intact during cooking. A study published in the Journal of Agricultural and Food Chemistry found that olive oil retained most of its phenols and antioxidants even after being heated to 180°C for 36 hours. In fact, cooking with olive oil may even enhance the absorption of some nutrients from vegetables.
Myth #3: Olive Oil Shouldn’t Be Used for Deep Frying
This myth likely stems from the misconception about olive oil's smoke point. In reality, olive oil can be used for deep frying, although it may not be the most economical choice. A study carried out by the University of Granada found that olive oil remained stable under deep-frying conditions and produced fewer harmful compounds compared to other vegetable oils.
Myth #4: Color indicates olive oil quality
The color of olive oil can range from golden to deep green, but this variation is not an indicator of quality. The color is influenced by factors such as olive variety, ripeness at harvest, and processing methods. Professional tasters use blue glasses to evaluate olive oil to avoid being influenced by color.
Myth #5: Olive oil gets better with age
Unlike wine, olive oil does not improve with age. Fresh olive oil is best, as it contains the highest levels of beneficial compounds. Over time, olive oil can become rancid, losing its flavor and nutritional value. It's recommended to use olive oil within 12-18 months of its harvest date for optimal quality.
Myth #6: Refrigerating olive oil proves its quality
The refrigeration test, where genuine olive oil is supposed to solidify in the fridge, is not a reliable indicator of quality or authenticity. Different olive oils may react differently to cold temperatures based on their fatty acid composition, which can vary naturally. The best way to ensure quality is to purchase from reputable sources and look for certifications.
Myth #7: "Light" olive oil has fewer calories
"Light" olive oil does not refer to its caloric content. All olive oils, regardless of their label, contain about 120 calories per tablespoon. The term "light" typically refers to the oil's flavor profile or color, often indicating that it has been refined.
