When it comes to choosing the right deep-frying oil, it is necessary to focus on nutrition and stability. Deep frying involves cooking the oil first to high heat, which is around 160 – 180° Celsius.

Well, there are oils that oxidize at such high temperatures and lose their stability. Such oils are unhealthy, as they release risky free radicals that can trigger a number of ailments such as cancer. Thus, the best oil for deep frying is resistant to being oxidized and getting rancid at such temperatures.

Best Oil for Deep Frying – 3 Ideal Oils

So, how to find this out? Well, you can find out by the relative extent of saturation of the oil’s fatty acids. This requires you to know the number of bonds between their molecules. While saturated fats contain single bonds, polyunsaturated fats have two or over two bonds. Monounsaturated fats contain double bonds.

The bonds of polyunsaturated fats are highly reactive to trigger oxidization. Thus, oils rich in such fats should not be used for deep frying. It is better to go for oils rich in saturated and monounsaturated fats.

While assessing the stability at a high temperature, do also focus on the smoke point, the temperature level that breaks down the oil and results in smoke.

Moreover, the best fat for deep frying is somewhat dissimilar to the right oil for regular cooking or stir-frying. For instance, a little butter is fine for pan frying some potato chips. However, the proteins and sugars in butter tend to burn at a high temperature due to which it is not ideal for deep frying.
