With the development of economy and the improvement of people's living standards, modern people have higher and higher requirements for healthy diet and quality of life. There are many kinds of edible oils on the market, but what is the difference between them? How should consumers choose to buy and use?
Several kinds of edible oils commonly used in daily life are quite different. First of all, the main raw materials of salad oil are rapeseed and soybean, its taste and color are relatively light, the content of unsaturated fatty acids and vitamin E is higher. In contrast, although peanut oil and salad oil have some similarities in the content of these two components, peanut oil is darker and more fragrant.
In recent years, olive oil has gradually become a new favorite of consumers, which is due to its high content of monounsaturated acid, which can prevent the body from oxidative damage and the problem of high blood lipid. Most of the products on the market are imported, and we can also choose camellia oil with similar fatty acid ratio as a substitute.
Corn oil, also known as corn germ oil, is the oil extracted from the embryo of corn seeds. It is also a kind of edible oil that we often see in our life. Its unsaturated fatty acid content is higher, and its fatty acid composition is similar to sunflower seed oil. But the latter is rich in vitamin E and chlorogenic acid, so it has higher nutritional value and more unique flavor.
For a wide range of edible oils, the key is to choose the right one. For patients with "three high" and other diseases, as well as the elderly with cardiovascular and cerebrovascular diseases, olive oil, tea oil and salad oil should be chosen as far as possible, and butter and animal oil should be reduced or avoided as far as possible. If you want to supplement vitamin E, you can choose corn oil and peanut oil. When purchasing peanut oil, we should avoid choosing virgin peanut oil because it may contain carcinogen aflatoxin. For consumers with no special needs, we can buy blended oil or a variety of edible oils and use them alternately to ensure a balanced diet.
In the process of using, we should use it scientifically according to the characteristics of different edible oils and the differences of cooking methods. Except olive oil is not suitable for high temperature use, other types of edible oil can be used for frying. For high temperature frying cooking method, salad oil can be selected as far as possible, because of its higher thermal stability.
