In June last year, Consumer Report sent 9 edible blending oils to a third-party testing agency, mainly testing the fatty acid composition of the oil.
<h1 class="pgc-h-arrow-right" > a comprehensive evaluation of 9 blending oils, which perform well and which are not recommended? </h1>
These 9 edible blending oils are the most common in our daily lives, including Arowana Edible Blending Oil, Arowana Golden Ratio Blending Oil, Lu Hua, Longda, Jiusan, Longevity Flower, Eagle Mark, Duoli, and Fu Linmen.
The main test indicators are saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids, omega-6 fatty acids, omega-3 fatty acids, trans fatty acids, and trichloropropanol.

We often hear slogans like 1:1:1 in cooking oil ads, which are meant to show that the fatty acid composition of the blended oils sold by ourselves is balanced. But what is the reality? Detection data does not lie.
The fatty acids of edible oil are mainly divided into three types: saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids. The balanced proportion of fatty acid intake has very great health significance for the human body, but in reality, because of the imbalance in fatty acid intake, it has become one of the reasons for the high incidence of chronic diseases in the public.
The test results showed that the ratio of the three fatty acids of all 9 blended oils did not reach 1:1:1 or greater than 1:1:1, which also shows that the so-called advertising words are just marketing methods.
However, according to the medical community, whether dietary fatty acids 1:1:1 is better has been questioned. The Chinese Nutrition Society has abolished the intake limit of monounsaturated fatty acids and retained only the intake recommendations for saturated fatty acids and polyunsaturated fatty acids. Therefore, consumers in their daily lives, do not eat a vegetable oil for a long time, try to rotate to eat, so that the intake of fatty acids can achieve a relative balance.
In addition, the human body cannot synthesize omega-6 fatty acids (n-6) and omega-3 fatty acids (n-3) on its own, which are two fatty acids that need to be obtained from food. These two fatty acids can regulate the body's immunity, control the inflammatory response and the formation of blood clots, but only in a certain proportion are beneficial. Clinically, cardiovascular diseases and certain cancers occur because of the long-term intake of these two types of fatty acids and the imbalance in proportion.
Peanut oil, corn oil, sunflower oil, sesame oil, the content ratio of these two fatty acids is high, so long-term single eating of one oil, is not good for health.
Therefore, the FAO's recommendation for the intake ratio of these two types of fatty acids is 5 to 10:1, and the intake recommendation of the Chinese Nutrition Society is 4 to 6:1. The results of the test showed that the 9 blended oils exceeded China's intake recommendations, and some of them were the most unbalanced, far exceeding the recommended values of China and FAO, reaching 82.3:1, 75.8:1 and 16:1, respectively.
This shows that in terms of nutritional composition, blended oil is not necessarily better than a single vegetable oil, so once again, in daily life, we must pay attention to as diverse as possible edible oil.
Finally, it should be pointed out that these 9 edible oils are safe, and none of them have detected trans fatty acids and pollutants trichloropropanol, so consumers can eat them with confidence.
<h1 class="pgc-h-arrow-right" > which is more nutritious and safer, blended oil or self-pressed oil? </h1>
In the choice of edible oil, due to the continuous explosion of gutter oil incidents, many consumers do not have confidence in the oil sold on the market. In this case, some people choose to eat self-pressed oil. So in the choice of oil, which is better, blending oil or self-pressed oil?
Blending oil itself is to maintain the balance of fatty acids in oil, it contains two or more kinds of oils, after a certain technical distribution and blending. The advantage of this is that the composition of fatty acids has reached a certain balance, the nutrients are richer, and the flavor of edible oil is improved, and the comprehensive advantages of blended oil are more obvious than that of a single vegetable oil.
And self-pressed oil, it is actually a single vegetable oil, the raw material may be peanuts, may also be sesame seeds, sunflower seeds and so on. Single vegetable oil, omega-6 fatty acids (n-6) and omega-3 fatty acids (n-3) are high in content, eating too much is not very healthy for the body, so from a nutritional point of view, the nutrition of self-pressed oil is single, and the proportion of fatty acid intake cannot be adjusted.
In addition to the single nutrition, self-pressed oil is mostly made in small workshops, and the safety of oil products faces two major risks.
The first risk is whether the raw materials are qualified. Lots of small self-pressed oil workshops. Due to reasons such as cost and improper storage, there is a problem of moldy raw materials, and the aflatoxin that appears will indirectly enter the edible oil, which poses a direct threat to human health.
The second risk is that the oil pressing technology will not be qualified. High temperature or technical substandard, some harmful substances produced will directly enter the edible oil, which is also a risk to health.
Therefore, the risk of self-pressed oil is very large, and in most cases, consumers cannot detect this risk in person. The blended oil on the market, on the one hand, has layers of quality inspection checks, food safety can be relatively assured, on the other hand, the nutritional composition of the blended oil is more reasonable and sufficient, compared to a single self-pressed vegetable oil, more beneficial to health. Therefore, the so-called pure peanut oil sold in the regular market and the small workshops, which is better, is judged from above.
< h1 class="pgc-h-arrow-right" > concluding remarks</h1>
In daily life, different cooking methods also differ in the use of oil. For example, fried chicken wings or fried buns, you can use soybean oil or corn oil, from the taste point of view, corn oil is fragrant, the best for frying. If it is a daily stir-fry, peanut oil and sunflower oil may taste better, but in cooking, you should pay attention to the oil temperature is not too high. If it is a stew or a cold mixture, sesame oil is better and the aroma is stronger.
It should be noted that even the healthier olive oil that is now advertised has the same fat content as other oils in principle. In the case of improved life regulation and diversified diet structure, the intake of oil is still critical. Eating less oil and eating safe and healthy oil needs to be maintained continuously.
