Corn oil, also known as corn oil and corn germ oil, is an oil extracted from corn germ. The content of unsaturated fatty acids is as high as 86%, among which polyunsaturated fatty acids dominate, and the content of linoleic acid is the highest. Corn oil is golden in color and transparent, with a tangy fragrance. It is one of the three healthy oil products recommended by the World Health Organization. Next, Benteng Machinery will introduce the advantages and efficacy of corn oil to you, as well as how to buy corn oil, how to eat corn oil and other related information.
1. High content of unsaturated fatty acids & essential fatty acids.
The content of unsaturated fatty acids in corn oil is very high, and the content of linoleic acid in the essential fatty acids of human body can reach 60%, which is a good source of linoleic acid in daily diet. In addition, the human body has a high absorption rate of corn oil, which can reach more than 97%.
2. There are many types and high content of nutrients.
Corn oil is rich in fat-soluble vitamins—vitamin E, and the content of phytosterols is higher than most common vegetable oils on the market. The content of phytosterols in some corn oils even exceeds 6000ppm. In addition, corn oil also contains phospholipids, squalene and other nutrients beneficial to the human body, and is a vegetable oil with high comprehensive nutritional value.
3. Less impurities, less cooking fumes.
Corn oil has a clear and transparent appearance with the least impurities and a high smoke point. Even in the process of high-temperature cooking, there is very little kitchen fume that is harmful to health. Therefore, corn oil is very suitable for daily Chinese cooking with high temperature and quick frying.
Ⅱ. How to choose the right corn oil?
1. The content of unsaturated fatty acids in the nutrient composition list.
Corn oil has a health care effect on middle-aged and elderly friends. The content of unsaturated fatty acids, especially the content of linoleic acid is an important indicator. Therefore, when choosing corn oil, try to choose corn oil with high linoleic acid content. According to national standards, the content of linoleic acid in corn oil should be 34.0-65.6%, that is to say, as long as it is a qualified product, the content of linoleic acid should be at least 34%.
2. Vitamin E content.
Vitamin E in corn oil is an antioxidant and heat resistant. Edible oil added with vitamin E is not easy to deteriorate. Vitamin E can also protect unsaturated fatty acids in the human body from free radical damage. Unsaturated fatty acids can reduce blood fat and cholesterol levels, prevent and reduce cardiovascular and cerebrovascular diseases.
3. Phytosterol content.
Phytosterols, also known as plant sterols, are an active ingredient in plants. According to statistics, the higher the dietary intake of plant sterols, the lower the risk of heart disease and other chronic diseases. Therefore, depending on the production process, the content of phytosterols retained in corn oil is different. It is recommended to choose edible oil with high phytosterol content.
Ⅲ. How to eat corn oil correctly?
1. Edible method -Cooking process: hot pot and cold oil.
Many people cook when the oil is smoking and they think that the hotter the oil, the better. In fact, when the oil temperature is high, the fatty acids will start to deteriorate, and polycyclic aromatic hydrocarbons will easily be produced. Carcinogens can also be produced when heated for too long.
The vegetable oils we use in our daily life all have the above characteristics and are rich in polyunsaturated fatty acids. Therefore, vegetable oils such as corn oil are not suitable for heating at high temperatures.
In fact, “hot pot with cold oil” is the best way of cooking, that is, heat the pot, put in the oil and stir-fry immediately without waiting for the smoke to avoid the above-mentioned unfavorable situation.
2. Food taboos.
Generally, corn oil is not suitable for infants, young children, people with fragile gastrointestinal tract, and postoperative patients.
In short, corn oil is a kind of edible oil with high comprehensive nutritional value. When consumers buy edible oil daily, they should practice “know how to cook and choose, and know how to read the label”, pay attention to the nutritional composition marked on the label, and choose the most suitable edible oil for them by combining the edible oil and its shape with the cooking method of daily habits. Although there are many benefits and efficacy of corn oil, you should consume it in moderation.
