Why Olive Oil Is the Best Oil for Frying Why olive oil is the best oil for frying October 14, 2016 Tweet Share Contrary to popular belief, olive oil is one of the best oils for frying. The medium-high smoke point of olive oil exceeds the temperatures needed for frying. Furthermore, olive oil contains oleic acid and minor compounds that protect the oil from breaking down, even after reuse. Frying is one of the most common and most delicious ways to prepare food. Throughout the Mediterranean, traditional foods like pescadillo, calamari, keftedes, patatas a la pobre, carcio alla giudea, and falafel are all fried in olive oil. Mediterraneans know that olive oil is the best oil for cooking and frying. So why do Americans believe that olive oil should only be used raw? The science Olive oil is one of the most stable oils for cooking. Unlike other common cooking oils, olive oil contains compounds and antioxidants that prevent the oil from breaking down under moderate heat. Additionally, olive oil is mostly composed of oleic acid (Omega-9), a monounsaturated fatty acid that is naturally resistant to oxidation. Multiple peer-reviewed studies have shown that olive oil is the best oil for frying. Olive oil outperformed vegetable, peanut, corn, soybean, sunower and canola oils. Olive oil can be heated to high temperatures - In 2013, Food Chemistry published a report comparing free radical formation and oxidation (rancidity) when heating peanut oil and extra virgin olive oil. The researchers found that more heat was needed to start the oxidation process in the extra virgin olive oil than in the peanut oil. Read more Olive oil can be reheated and reused safely - In 2014, the American Chemical Society's Journal of Agricultural and Food Chemistry published a study comparing rened olive oil with corn, soybean, and sunower oils. They deep-fried and pan- fried potatoes at heat up to 374°F for up to ten successive sessions. Olive oil was found to be the most stable, had the greatest resistance to oxidative deterioration, and its trans-fatty acid contents and harmful compounds were found to be lowest. Read more Olive oil can be heated to high temperatures for long periods of time - In 2012, Food Chemistry published a study comparing extra virgin olive oil to sunower oil. Both oils were heated in an industrial fryer at 374°F for 40 hours. The study found that extra virgin olive oil performed better than sunower oil. Read more Olive oil produces fewer harmful compounds when overheated - In 2004, a team studied the aldehydes produced by heating extra virgin olive oil, olive oil and canola oil to 464°F. The study found that both extra virgin and regular olive oil were healthier than canola oil. Read more Olive oil is also good for shallow frying - A 2016 study experimented with shallow frying sh at 340°F in both extra virgin olive oil and sunower oil. Olive oil performed better, showing more resistance to oxidation and degradation. Read more Frying in olive oil is heart healthier - Perhaps most interestingly, a study in the British Medical Journal states that there is no link between the consumption of fried foods and heart disease when the food was fried in olive oil. Read more Frying in olive oil may ght disease - A 2016 study found that vegetables fried in extra virgin olive oil contained more phenols and antioxidants than vegetables boiled in water. Read more. More peer review studies can be found here and here. Smoke point Often, the smoke point of olive oil is cited as the reason why olive oil should not be heated or used for cooking. However, a recent study found that smoke point is not a reliable indicator of a cooking oil's stability. Furthermore, the smoke point of olive oil is comparable, and in some cases higher than, common cooking oils such as soybean, sunower, peanut, canola and corn oils. The International Olive Council (IOC), the authority on olive oil, recommends the following temperatures for frying in olive oil. TYPE OF FOOD TEMPERATURE High water content: vegetables, potatoes, fruit Medium (266-293ºF or 130-145ºC) Coated in batter, our or breadcrumbs, forming a Hot (311-338ºF or 155-170ºC) crust Very Hot (347-374ºF or 175– Small, quickly fried: small sh, croquettes 190ºC) The smoke point of olive oils are above the temperatures needed for frying. The below chart shows the smoke points of olive oils and for reference, the smoke points of other oils commonly used for frying. The smoke points are listed as ranges. The actual smoke point depends on the free fatty acid content and level of renement. COOKING OIL/FAT SMOKE POINT °F Olive oil or extra light olive oil 390 - 468°F Sunower oil 440 - 450°F Soybean oil 440 - 450°F Canola oil 435 - 445°F Peanut oil 420 - 430°F Corn oil 400 - 415°F Extra-virgin olive oil 350 - 410°F Shortening 360°F Virgin Coconut oil 350°F Read more on the topic of measuring smoke points here and here. Tips for frying with olive oil 1. Regular olive oil and extra light tasting olive oil are the most cost ecient for frying. If cost is not a factor, consider using extra virgin olive oil. 2. Don't worry that your food will taste like olives. Heating olive oil will neutralize much of the avor. 3. Make sure that the oil is hot enough before adding the food (a thermometer is a good idea). Olive oil will help your food form a crust and will help prevent your food from absorbing too much oil. 4. Studies have shown that even as part of a Mediterranean diet, fried foods were associated with weight gain, so consume fried foods in moderation. Read more.

Several raw food have antinutritional factors which are destroyed by cooking. However, if proper care is not taken while cooking, several important nutrients rae destroyed. So, it is very important to employ proper method of cooking to avoid nutrient loss. Some methods employed before cooking 1. Peeling: It is a method of removing the outer firm skin before cooking or eating fruit or vegetable. Some of vegetables & fruits are eaten with the peel. 2. Chopping It involves cutting of fruits & vegetables. Food is cut into several sizes to create variety in the cooked food 3. Grinding & pounding In grinding, the food is reduced to very fine form like spices. Sometimes cereals are also ground to powder. Pounding is also like crushing food to reduce thickness for easier cooking. 4. Soaking Pulses & legumes are soaked for few hours before cooking to make cooking easier. 5. Sprouting or germinating This method is used for pulses, legumes & grains. This method not only add variety to food, but also increases the content of vitamin C & vitamin B complex in the food.

BIRADAR 1, 2, 3 Department of Mechanical Engineering, Rajgad Dnyanpeeth’s, Shri chhatrapati Shivajiraje College of engineering, Bhor, Pune, Maharashtra, India. ABSTRACT: Heat transfer is a very important aspect in the cooking process. Heating food destroys potentially harmful bacteria and other microorganisms, which makes food safe to eat and easier to digest. When food or liquids become hot, their molecules absorb energy, begin vibrating rapidly, and start to bounce off of each other. As they collide, heat energy is produced and transferred, which warms and cooks our food. Heat transfer is the process of an item or substance coming into contact with a heat source and becoming hot. In more scientific terms, heat transfer is an exchange of thermal energy between two objects. There are three methods of heat transfer namely conduction, convention and radiation. All these methods are being used in cooking methods. Taste and healthiness of the food is our prime requirement. Does mode of heat transfer affect the test and Vitamins and other contents in the food? Various cooking method and their corresponding mode of heat transfer has been discussed and investigated all aspects concerned with the topic . KEY WORDS: Cookware, Cooking methods, heat transfer in cooking I. Introduction: Human prime requirement of life to survive is food and water. Without food human can’t survive.
