Which cooking oil is best for frying

Most vegetable oils on the market are a blend of canola, corn, soybean, safflower, palm and sunflower oils. Still, vegetable oils are refined and processed, which means they not only lack flavor, but also nutrients, Howard says.

Canola oil is derived from rapeseed, a flowering plant, and contains a good amount of monounsaturated fats and a decent amount of polyunsaturated fats. Of all vegetable oils, canola oil tends to have the least amount of saturated fats. It has a high smoke point, which means it can be helpful for high-heat cooking. That being said, in the United States, canola oil tends to be highly processed, which means fewer nutrients overall.

Avocado oil is a great choice. Avocado oil contains both monounsaturated and polyunsaturated fatty acids it has one of the highest monounsaturated fat contents among cooking oils as well as vitamin E. One downside is that it tends to be more expensive.

However, sunflower oil contains a lot of omega-6 fatty acids. The body needs them, but omega-6s are thought to be pro-inflammatory, while omega-3s are anti-inflammatory. Consuming too many omega-6s without balancing with omega 3s, could lead to an excess inflammation in the body, so moderation is key. Nut oils, like peanut, can be fun to experiment with in the kitchen, especially since there are so many different types. Peanut oil has one of the highest monounsaturated fat contents among cooking oils.

Submerge a food in oil at this temperature causes its surface to cook almost instantly. As it cooks, it forms a type of seal that the oil cannot penetrate. At the same time, the moisture inside the food turns into steam, cooking the food from the inside. The steam also helps keep the oil out of the food.

Deep frying involves submerging food in hot oil. At the right temperature, this will instantly cook the surface and trap the moisture inside the food. However, cooking oils that contain large amounts of polyunsaturated fats are less suitable for frying 1.

This is because polyunsaturated fats contain two or more double bonds in their chemical structure. These double bonds can react with oxygen and form harmful compounds when exposed to high heat. Coconut oil may have various other health benefits.

One study suggests that it may help you lose belly fat 6. When choosing coconut oil, bear in mind that some varieties can leave a flavor or smell that not everyone enjoys.

A range of possible health benefits may make coconut oil a good choice for frying. Animal fats, such as lard, tallow, ghee , and fat drippings, can be excellent choices for deep frying. Most fatty acids in animal fats are saturated and monounsaturated. This makes them resistant to high heat. Grain-fed animals may have more polyunsaturated fatty acids in their fat stores than pasture-raised or grass-fed animals.

Butter is unsuitable for deep frying. It contains small amounts of carbs and protein that burn when heated. Clarified butter and ghee are better options. Animal fats consist mainly of saturated and monounsaturated fats, making them suitable for cooking at high temperatures.

Olive oil is one of the healthiest fats. These have only one double bond, making them relatively stable. In one study, researchers used olive oil in a deep fryer for over 24 hours before it oxidized excessively In theory, this makes it a great choice for deep frying. The last factor you might consider is whether a given cooking oil is more or less healthy. The good news is that all cooking oils that are liquid at room temperature are pretty good for you.

So your choices really come down to choosing ones that are healthy versus very healthy. And the degree of healthiness comes down to its ratio of polyunsaturated fats, which are the so-called good fats which increase your HDL the "good" cholesterol and lower your LDL "bad" cholesterol , as well as having a relatively low level of saturated fats, which are the so-called " bad fats. The oils with the highest polyunsaturated fats are sunflower and safflower oil, both of which have smoke points in the range of to F for their refined versions.

The oil with the lowest level of saturated fat happens to be canola oil, whose smoke point of to F makes it an excellent choice for deep frying. Lastly, there is the issue of cost, since for deep-frying, you might be using anywhere from two cups to two quarts of oil at a time. And yes, you can reuse your oil, but that's still quite a lot of oil to buy as an up-front expense.

Avocado oil, with a smoke point of F, is even more expensive. Its high smoke point and low level of saturated fat make it a compelling choice. And because it is neutral in flavor, it won't impart any additional flavors to your food. Which means that by any measure, whether it's smoke point, health or cost, canola oil is the best oil for deep-frying. Actively scan device characteristics for identification.
