Cooking oil can be mixed and used with different cooking methods.Like olive oil, it has a high content of monounsaturated fatty acids and many nutrients in virgin oil, which will produce a unique fragrance and is suitable for cold salad.Some consumers believe that olive oil is rich in unsaturated fatty acids, so they prefer to use olive oil when cooking.Xu Chunxiang said that cooking oils contain various types of fatty acids, but each has different content. Usually through identification tests, the composition of fatty acids can be used to determine which kind of oil it is.“Oils with high unsaturated fatty acids are not suitable for frying."He explained that oils with high unsaturated fatty acids are not easy to form cholesterol, but because unsaturated fatty acids are unstable, they are easy to break chains after heating, and they are easy to oxidize and polymerize after frying, which may produce substances that are not conducive to health.Like the palm oil used in instant noodles, it has a high content of saturated fatty acids and is stable after heating, making it suitable for frying oil.When cooking with oils high in unsaturated fatty acids, special attention should be paid to the heating time must not be too long.
