Edible oil can be mixed and used together
Edible oil can be mixed with different cooking methods. For example, olive oil has high monounsaturated fatty acid content and nutrient components in the primary oil, which can produce a unique fragrance and is suitable for cold mix. Some consumers believe that olive oil is rich in unsaturated fatty acids, so they prefer to use olive oil in cooking. Xu Chunxiang said that cooking oil contains all kinds of fatty acids, but they have different contents. Usually through identification tests, we can judge which kind of oil is by the composition of fatty acids. "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 of the instability of unsaturated fatty acids, they are easy to break chains after heating and easy to oxidize and polymerize after frying, which may produce unhealthy substances. For example, the palm oil used in instant noodles has high saturated fatty acid content and is stable after heating, so it is suitable for frying oil. When stir-frying vegetables with high unsaturated fatty acids, special attention should be paid to the heating time must not be too long.
