1, tea oil (tea seed oil)
Tea oil is called "Oriental olive oil", but it is much healthier and more environmentally friendly than olive oil. Tea oil is mainly extracted from tea seeds, and the content of monounsaturated fatty acids reaches 80-83%, which is much higher than olive oil. Tea oil has high smoke point and good heat resistance, which is suitable for daily cooking in families. In addition, tea oil is rich in vitamin E, which can replace olive oil as raw material for skin care products.
2. Walnut oil
Walnut oil is a vegetable oil squeezed from walnuts. Its unsaturated fatty acid content is more than 90%, and it is also rich in antioxidant components such as vitamin E, phospholipids and a lot of polyphenols. But it is not suitable for heating, and it is mostly used for cold salad or raw food. So troublesome friends recommend eating 2-3 walnuts every day, and the effect is the same.
3. Olive oil
Olive oil has always been regarded as a healthy oil, mainly because it is rich in unsaturated fatty acids and vitamin E, and can be used as raw materials for food and cosmetics. In addition, the price of olive oil is more expensive than other oils, and olive oil is easily adulterated. Cooking methods are mostly used in cold salad, which is not suitable for all kinds of cooking methods in China, so it is not recommended that our family should focus on cooking oil.
4. Sesame oil
Sesame oil, also known as sesame oil in the north, is the oil squeezed from white sesame or black sesame. As the name implies, it has an attractive fragrance, but it is not resistant to high temperature, so it is often used for cold dishes, dipping materials, flavoring soup and mixing jiaozi. It is rich in vitamin E and sesamol, and has good antioxidant effect.
5. Rice bran oil
Rice bran oil is the oil contained in rice germ and rice bran. It contains more than 80% unsaturated fatty acids and is rich in vitamin E. In addition, rice bran oil is rich in γ -aminobutyric acid. Rice bran oil has moderate heat resistance and is suitable for home cooking. Its only disadvantage is that it is easy to produce Aspergillus flavus, so you'd better buy qualified refined oil.
