efficacy
Research by Chinese Academy of Preventive Medicine confirmed that the zinc content of peanut oil is 37 times that of salad oil, 32.6 times that of corn oil, 16 times that of rapeseed oil and 7 times that of soybean oil. Although there are many ways to supplement zinc, oil is a necessary supplement for people, so edible peanut oil is especially suitable for people to supplement zinc. Nutritionists also found that peanut oil contains three health-care components beneficial to cardiovascular and cerebrovascular diseases: resveratrol, rich monounsaturated fatty acids and β -sitosterol. Experiments show that these substances are chemopreventive agents for tumor diseases, reduce platelet aggregation, prevent and treat arteriosclerosis and cardiovascular and cerebrovascular diseases, and are one of the ideal edible oils for middle-aged and elderly people. High-quality peanut oil contains a variety of anti-aging ingredients, which has the effect of delaying the aging of brain function.
Applicable people
Suitable for all people, especially middle-aged and elderly people.
Applicable amount
40 grams a day.
≮ Special tips ≯
Peanut oil is resistant to high temperature, and it is suitable for frying food except cooking. After all, it is high in calories and fat. Eating too much will still have a certain impact on cardiovascular and cerebrovascular diseases, and it is easy to get fat.
Peanut oil has high nutritional value.
Internationally, people have reached a consensus that peanuts are a very healthy food. As a result, peanut products such as peanut oil and peanut butter are more and more loved by people. In fact, the nutritional value of peanut oil is indeed as rich as peanut. With the deepening of research, scientists found that peanut oil is rich in unsaturated fatty acids, accounting for more than 75%, of which monounsaturated fatty acids exceed 50%. At the same time, the role of monounsaturated fatty acids is gradually understood by people. At present, scientists have mastered the knowledge that monounsaturated fatty acids can reduce blood cholesterol, prevent atherosclerosis and coronary heart disease, and reduce cardiovascular harm by 2 1%.
In addition, peanut oil also contains 13 vitamins and 26 mineral elements, rich in vitamin E and folic acid, as well as mineral elements such as zinc, calcium, phosphorus and iron. Each of these 26 elements is essential to the human body. Supplementing the intake of these nutrients through diet can enhance physical fitness and help improve the nutritional deficiency and malnutrition of Chinese residents.
For example, per 100g peanut oil contains 8.48mg of zinc, which is 37 times that of salad oil, 32.6 times that of corn oil and 7 times that of soybean oil. Zinc can promote children's brain development, activate brain cells of middle-aged and elderly people, and has a certain effect on delaying aging. In addition, scientists also found some phytoactive chemicals in peanut oil, including phytosterols, resveratrol, isoflavones, B- sitosterol, etc., all of which have important health care functions. Nutrition research has confirmed that phytosterol is a lipid compound, which is not absorbed by human body, prevents cholesterol absorption and can effectively prevent cardiovascular and cerebrovascular diseases. B- sitosterol has the effects of lowering cholesterol and preventing cardiovascular and cerebrovascular diseases and cancer.
Picking peanut oil for a healthy society
During holidays, it is easy for people to be surrounded by delicious food. At this time, we should pay more attention to the balance of diet and replenish the body with necessary energy. Nutritious peanuts and peanut oil are undoubtedly our best choice. However, readers should be reminded that if you choose to eat peanut oil as a simple and powerful support for health, not every peanut oil sold in the market has rich nutritional value. Some fake and shoddy products not only can't add vitality to the body, but are even harmful to health. When choosing peanut oil, we should not only look for the products produced by regular manufacturers, but also know how to judge. The main distinguishing means lies in the production process of oil. The leaching process will destroy the nutrition of peanuts, while pure physical pressing can completely retain the natural nutrition of peanuts. (Evening News)
Verification of China Nutrition Education Research Report;
Peanut oil is really good for health.
Recently, China Journal of Nutrition published an experimental report of Shandong University on the effect of peanut oil on the blood lipid level of middle-aged and elderly people in China.
Sixty-five healthy middle-aged and elderly people (40-60 years old) were selected in the experiment, and each person used four different recipes successively: a, basic diet, that is, original diet, more animal fat intake and salad oil for cooking; B, a low-fat and high-carbohydrate diet; C, peanut oil diet, using peanut oil instead of salad oil to reduce the intake of animal food; Peanut oil and peanut diet.
Experimental results: Compared with the basic diet, peanut oil diet rich in oleic acid, peanut oil plus peanut diet and low-fat diet reduced total cholesterol and harmful cholesterol. Professor Xu Guifa of Shandong University said, for example, Lu Hua, who participated in the experiment, this advanced squeezing technology can retain the active substances in peanuts to the maximum extent, such as fat-soluble vitamins, phytosterols, resveratrol, etc., and it also plays a beneficial role in the process of regulating blood lipids.
Peanut oil and olive oil have their own advantages, and peanut oil is more suitable for mass consumption.
Peanut oil and olive oil have become favorite edible oils for consumers at home and abroad. Its * * * is the same:
No cholesterol, high oleic acid content. Olive oil has the highest oleic acid content, up to 60%-84%. Peanut oil accounts for 42-68%, which is 2-3 times that of other vegetable oils such as soybean oil, sunflower oil and corn oil.
They are all squeezed into oil. Peanut oil and olive oil are both pressed to make oil, which ensures the safety, hygiene and pollution-free of refined oil.
The difference between the two is that olive oil is light and suitable for western tastes; Peanut oil has a strong aroma, which is more suitable for China people's traditional eating habits. The market price of olive oil is expensive, which is 10 times that of ordinary edible oil; Peanut oil is more than ten yuan a catty, which is acceptable to most urban residents.
Advanced nutritional oil sunflower seeds
Sunflower seed, also called sunflower seed, is the fruit of sunflower. Its nuts contain 30%-45% fat, up to 60%. Sunflower seed oil is golden in color, clear and transparent, and fragrant in smell. It is an important edible oil. It contains a lot of unsaturated fatty acids such as linoleic acid, which can promote the regeneration and growth of human cells, protect skin health and reduce the accumulation of cholesterol in blood. It is a kind of advanced nutritional oil.
Sunflower seed oil is rich in carotene, more than peanut oil, sesame oil and soybean oil. Therefore, it can reduce the concentration of serum cholesterol, prevent arteriosclerosis and vascular diseases, and is very suitable for hypertensive patients and middle-aged and elderly people.
Sunflower seed oil also contains more vitamin E, about 100- 120 mg per hundred grams. Therefore, it has a good effect of delaying the aging of human cells and maintaining youth. Regular consumption can strengthen the body and prolong life.
Sunflower seed oil also contains more vitamin B3, which is effective in treating neurasthenia and depression. It contains a certain amount of inorganic substances such as protein, potassium, phosphorus, iron, magnesium, etc., which is very effective in treating diabetes and iron deficiency anemia, and is of great significance for promoting the healthy growth of teenagers' bones and teeth. It contains linoleic acid, an essential fatty acid for human body, which is helpful for human development and physiological regulation, and also has a positive effect on preventing skin dryness and scale hypertrophy.
Sunflower seed oil also contains nutrients such as glucose and sucrose, and its calorific value is higher than that of soybean oil, peanut oil, sesame oil and corn oil, and it can produce 9.499 calories per gram. Its melting point is also low, suitable for human absorption, and the absorption rate can reach above 98%. In addition, it is slightly hot and fragrant. It is the best edible oil besides sesame oil.
Because sunflower seed oil is rich in nutrition and has many health functions for human body, it is known as "advanced nutritional oil". In recent years, it has been selling well in the international market and is deeply favored.
Want health? Eat peanut oil!
2003-6-6
At the beginning of the Spring Festival in 2003, the Great Hall of the People chose pure peanut oil with special flavor of Lu Hua as the oil for the state banquet. This not only further established the outstanding position of "Lu Hua" in high-quality peanut oil, but also aroused people's great concern about peanut oil, which triggered people's discussion on the nutritional value, health care function and the function of improving people's diet structure. Let's listen to the opinions of several famous nutritionists and medical experts.
Use peanut oil to reduce heart disease
A study by American Nutrition Society and Cincinnati Medical College shows that people who eat peanut oil have "two lows and one high": low blood lipid, low harmful cholesterol and high beneficial cholesterol. Another survey of 80082 women in the United States for several years found that monounsaturated fatty acids, the main component of peanut oil, are important cardioprotective factors for preventing coronary heart disease.
In the study of modern people's diet, the American Heart Association found that Greece, especially Crete, had the lowest incidence of cardiovascular diseases, while Finland and the United States had the highest incidence. The only significant difference between Greece and the other two countries is the different types of fat consumed by its residents. Studies have shown that monounsaturated fatty acids are consumed in large quantities in countries with low mortality from cardiovascular diseases. Professor Mao, a national expert with outstanding contributions, said that edible oil is mainly composed of saturated fatty acids, monounsaturated fatty acids, polyunsaturated fatty acids and trace elements. Nutritionists at home and abroad agree that judging the quality of an edible oil mainly depends on the content of monounsaturated fatty acids in the oil. The higher the content of monounsaturated fatty acids, the higher the nutritional value and health care function.
Among the main edible oils in China, peanut oil has the highest monounsaturated fatty acid content, reaching 48%, while the monounsaturated fatty acid content of corn oil, soybean salad oil, rapeseed salad oil, most blended oil and sunflower seed oil is only equivalent to1/3 ~12 of peanut oil. Polyunsaturated fatty acids are commonly found in corn oil, salad oil, sunflower oil and safflower oil.
There are two kinds of cholesterol: low density lipoprotein (LDL) and high density lipoprotein (HDL), which are also called "bad cholesterol" and "good cholesterol" respectively. The former is harmful to the human body, while the latter can remove cholesterol, transfer it to the liver and excrete it through the bile duct. Polyunsaturated fatty acids not only reduce the content of "bad cholesterol", but also reduce the content of "good cholesterol". Monounsaturated fatty acids can not only reduce the content of "bad cholesterol", but also significantly increase the content of "good cholesterol", thus preventing cholesterol deposition and reducing the incidence of cardiovascular diseases.
China's "longevity fruit" is American Toona sinensis.
Professor Xu Guifa, director of the China Nutrition Society and a member of the American Nutrition Society, said that in recent years, there has been a craze for eating peanuts and peanut oil in the United States. At the same time, American nutritionists introduced a series of peanut anti-aging achievements to residents. This verifies the rationality of the ancient peanut name "longevity fruit" in China. Their experiments on peanuts and peanut oil show that peanuts contain a variety of anti-aging components, especially five anti-aging components such as monounsaturated fatty acids, resveratrol, β phytosterol, folic acid and trace element zinc. These components play an important role in regulating human functions and preventing cardiovascular and cerebrovascular diseases.
Professor Xu said that there are great differences in the basic views of Chinese and American residents on peanuts. Many people in our country think that peanuts are easy to make people fat, and a research result of Harvard University proves that peanuts are the main content of dieters' diet, and peanut food is a daily food deeply loved by American residents.
A top two, a top three.
Professor Mao said that he and a famous restaurant host had done an interesting experiment, using pure peanut oil, common blended oil and salad oil to make the same dish. The results showed that the dosage ratio was 1∶2.5∶3 to meet the requirements of the same color, fragrance and taste. Peanut oil is simply a top two and a top three.
He told consumers that when switching from other edible oils to peanut oil, they must not make empirical mistakes. We usually use three or two, but now we can use one or two or five, which is economical and practical, and can reduce the body's intake of fat and prevent obesity.
Professor Mao quoted figures from China College of Preventive Medicine as saying that the zinc content in peanut oil is as high as 8.48 mg per 100 grams, which is 37 times that of salad oil, 0/6 times that of rapeseed oil and 7 times that of soybean oil. As we all know, zinc is an indispensable trace element for human body. Supplementing more zinc can enhance the body's disease resistance and delay the decline of brain cells and human functions. Children can eat more foods rich in zinc, which can stimulate appetite, promote physical development and promote intellectual development.
Squeeze raw materials and eat green
It is understood that there are two popular edible oil processing methods in China at present: one is leaching method, which requires solvent elimination, high-temperature refining, decoloration and deodorization in the production process, which will inevitably cause the loss of some nutrients. This method is used for most salad oils and blended oils. One is the squeezing method represented by Lu Hua, the first brand of peanut oil in China. The principle of this process is: the oil is separated from the raw materials by physical pressing, and no chemical substances are used to ensure the original flavor of the product, which is safe, hygienic and pollution-free.
Professor Mao said that the domestic peanut oil pressing technology has made a breakthrough. Luhua Texiang pure peanut oil, which adopts the core technology of 5S pure physical squeezing technology, has reached or exceeded the level of internationally renowned brand products in terms of color, taste and internal quality, and has been exported to more than a dozen countries and regions. It is a green food that ordinary people can safely eat.
People in Hangzhou may not know much about peanut oil. But when I arrived in Beijing, I found that peanut oil was really dazzling, and other edible oils were not easy to buy.
In fact, peanut oil was rarely seen in Beijing before 1998. With the enhancement of consumer rationality and the improvement of consumption level, peanut oil currently occupies a dominant position in Beijing edible oil market. Whether it is frying, frying, boiling, frying or cold salad, it is inseparable. Most famous restaurants and hotels use peanut oil.
Wang Ruiyuan, president and chief expert of Oil Branch of China Grain and Oil Association, believes that peanut oil has extremely high nutritional value, and its performance conforms to the eating habits of the orientals. Peanuts in China have obvious advantages in scale and quality in the world. What is certain is that peanut oil will become one of the main characters on the dining table of China people in a few years, because the healthy life of ordinary people really cannot be separated from it.
Look, how important peanuts and peanut oil are! (Zhejiang Daily)
Cooking oil, don't always stare at one food.
In the past two decades, people have consumed too many high-calorie foods, including fat, or improperly selected fat, which has led to high incidence of diseases such as overweight, obesity, arteriosclerosis, hyperlipidemia, hypertension and gallstones. However, there are different views on various edible oils in society. Faced with all kinds of edible oils on the market, the people are at a loss. So how should we treat these problems?
Edible oil has its own characteristics.
olive oil
It contains monounsaturated fatty acids, which is the highest among all edible oils. It has good effects of reducing low-density cholesterol (bad cholesterol) and increasing high-density cholesterol (good cholesterol), so it has the effects of preventing cardiovascular and cerebrovascular diseases and reducing cholecystitis and gallstones. Olive oil also contains vitamins A, D, E, K and carotene, which has a certain effect on improving digestive function, enhancing calcium deposition in bones and delaying brain atrophy. However, olive oil is expensive, tasteless and lacks attractive fat flavor, so most people in China don't like its taste very much.
Tea seed oil
Monounsaturated fatty acids are similar to olive oil, so they are called "Oriental olive oil". It is reported that the incidence and mortality of cardiovascular diseases among residents in a tea oil producing area are lower than those in other areas.
rap oil
It contains high monounsaturated fatty acids, so it has the effect similar to olive oil and is good for gallbladder. Rapeseed oil is the lowest price among all edible oils rich in monounsaturated fatty acids, so it is becoming more and more popular.
peanut oil
It is rich in oleic acid, lecithin, vitamins A, D, E, K and natural polyphenols with strong biological activity, so it has the functions of reducing platelet aggregation, reducing the levels of total cholesterol and bad cholesterol, and preventing arteriosclerosis and cardiovascular and cerebrovascular diseases. People think that eating too much peanut oil is easy to get angry, which is because arachidonic acid in peanut oil causes allergic reaction in human body.
Soybean oil
Rich in polyunsaturated fatty acids and vitamins E and D, it can reduce cardiovascular diseases, improve immunity, and increase weight for the weak and emaciated. Soybean oil contains more polyunsaturated fatty acids, so it is the most prone to rancidity among all kinds of oils. So when you buy it, you must choose something that has not been delivered for a long time and try to eat it fresh.
sunflower seed oil
Rich in essential fatty acids, linoleic acid and α -linolenic acid can synthesize DHA related to brain nutrition in vivo, and sunflower oil for pregnant women is beneficial to fetal brain development; Vitamins E and A contained in it have the functions of softening blood vessels, lowering cholesterol, preventing cardiovascular and cerebrovascular diseases, delaying aging, preventing dry eye, night blindness and dry skin. It also contains high polyunsaturated fatty acids, so it has the same precautions as soybean oil.
salad oil
It is the edible oil with the highest processing grade among vegetable oils. Basically, all impurities and waxes in vegetable oils have been removed, so the color is the lightest. Salad oil is suitable for frying, frying, frying and cold salad, which is beyond the reach of other edible oils.
sesame oil
Known as the "king of vegetable oil", it is rich in a variety of unsaturated fatty acids, protein, calcium, phosphorus, iron, lecithin, vitamins A, D and E, and has the functions of scavenging free radicals, improving immunity, delaying aging, preventing constipation, coronary heart disease, diabetes, premature gray hair and beauty beauty. Chinese medicine believes that patients with emphysema can relieve cough symptoms by drinking a little sesame oil before going to bed and getting up the next day.
lard
It contains high saturated fatty acids, and eating too much can easily lead to hyperlipidemia, fatty liver, arteriosclerosis and obesity. But don't be afraid to eat it, because the cholesterol it contains is the raw material for the human body to make steroid hormones, adrenocortical hormones, sex hormones and synthesize vitamin D by itself. The α -lipoprotein in lard can prolong the life of animals, which is lacking in vegetable oil. (Professor Jiang Jia from Shanghai Center for Disease Control and Prevention)
Different oils have different nutrition, so we can't absolutely say which one is good. In the long run, it is not good to eat only one kind of oil. From this point of view, blending oil is more balanced. But the main ingredient of that cheap blended oil is actually soybean oil. So if it is cheap blended oil, it is definitely not as good as peanut oil. The cost of real peanut oil is 60-70 yuan, which is relatively high, so cheap peanut oil is not real peanut oil. I personally like to eat soybean oil, probably because I am from the Northeast, and we have eaten soybean oil since childhood.
Nutritional characteristics of several edible vegetable oils
1, peanut oil
Peanut oil is light yellow, transparent, clear in color, fragrant and delicious, and it is an easy-to-digest edible oil. Peanut oil contains more than 80% unsaturated fatty acids (including oleic acid 4 1.2% and linoleic acid 37.6%). In addition, it also contains 19.9% saturated fatty acids such as palmitic acid, stearic acid and arachidic acid.
Judging from the above, peanut oil has a good fatty acid composition and is easily digested and absorbed by the human body. According to foreign data, the use of peanut oil can decompose cholesterol in human body into bile acid and excrete it, thus reducing the cholesterol content in plasma. In addition, peanut oil also contains sterols, wheat germ phenol, phospholipids, vitamin E, choline and other substances beneficial to the human body. Regular consumption of peanut oil can prevent skin wrinkles and aging, protect blood vessel walls, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease. Choline in peanut oil can also improve the memory of human brain and delay the decline of brain function.
2. Rapeseed oil
Rapeseed oil is generally dark yellow or brown. Rapeseed oil contains 0.4- 1.0% arachidic acid, 0.4-19% oleic acid, 0.2-24% linoleic acid, 3 1-55% erucic acid and 0/-linolenic acid. In terms of nutritional value, the digestibility of rapeseed oil can be as high as 99%, which is beneficial to gallbladder function. When the liver is in a pathological state, the human body can also metabolize rapeseed normally. Rapeseed oil lacks essential fatty acids such as linoleic acid, and its fatty acid composition is unbalanced, and its nutritional value is lower than that of ordinary vegetable oil. In addition, rapeseed oil contains a lot of erucic acid, glucosinolates and other substances, which are generally considered to be unfavorable to human growth and development. If it can be eaten with high-quality edible oil rich in linoleic acid, its nutritional value will be improved
3. Sesame oil
Sesame oil includes common sesame oil and ground sesame oil, both of which are made of sesame oil. The fatty acids of oil extracted from sesame, whether sesame oil or ground sesame oil, generally contain oleic acid 35.0-49.4%, linoleic acid 37.7- 48.4% and arachidic acid 0.4- 1.2%. The digestion and absorption rate of sesame oil reached 98%. Sesame oil contains no harmful ingredients, but it is especially rich in vitamin E and linoleic acid. Regular consumption of sesame oil can regulate capillary permeability, strengthen the oxygen absorption capacity of human tissues, improve blood circulation, promote gonadal development, delay aging and maintain youthful appearance. Therefore, sesame oil is a high-quality edible oil with good edible quality and high nutritional value.
4. Cottonseed oil
Refined cottonseed oil is generally orange-yellow or brown, and the fatty acids contain palmitic acid 2 1.6-24.8%, stearic acid 1.9 -2.4%, arachidic acid 0.1%,oleic acid 18.0-30.7% and linoleic acid 44. Cotton clear oil contains a lot of essential fatty acids, and it is best to mix with animal fat, because the linoleic acid content in cotton clear oil is particularly high, which can effectively inhibit the rise of cholesterol in blood and maintain human health. The absorption rate of cotton oil in human body is 98%.
5. sunflower seed oil
The refined sunflower seed oil is clear and beautiful pale yellow or bluish yellow, with fragrant smell and pure taste. The composition of fatty acids in sunflower seed oil is influenced by climatic conditions. Sunflower seed oil produced in cold areas contains about 65438 05% oleic acid and 70% linoleic acid. Sunflower seed oil produced in warm areas contains about 65% oleic acid and 20% linoleic acid. The digestibility of sunflower seed oil is 96.5%. Rich in linoleic acid, it can significantly reduce cholesterol, prevent arteriosclerosis and prevent coronary heart disease. In addition, the content of tocopherol A with the strongest physiological activity in sunflower seed oil is higher than that in general vegetable oil. Moreover, the ratio of linoleic acid content to vitamin E content is relatively balanced, which is convenient for human body to absorb and utilize. Therefore, sunflower seed oil is an excellent edible oil with high nutritional value and beneficial to human health.
6. Linseed oil
Linseed oil is also called linseed oil. Linseed oil contains 9- 1 1% saturated fatty acid, 13-29% oleic acid, 15-30% linoleic acid and 44-6 1% linolenic acid. Linseed oil has a special smell, and its edible quality is not as good as peanut oil, sesame oil and sunflower oil. In addition, because it contains too much flax oleic acid, its storage stability and thermal stability are poor, and its nutritional value is also lower than that of edible oil mainly composed of linoleic acid and oleic acid.
7, safflower seed oil
Safflower seed oil contains 6% saturated fatty acid, 2 1% oleic acid and 73% linoleic acid. Because its main component is linoleic acid, its nutritional value is particularly high, which can prevent the deposition of human serum cholesterol on the blood vessel wall and prevent atherosclerosis and cardiovascular diseases. In the pharmaceutical industry, safflower seed oil can be used to make drugs to prevent and treat cardiovascular diseases, hypertension, liver cirrhosis and other diseases, such as Yishouning. In addition, safflower seed oil also contains a large number of medicinal components such as vitamin E, oryzanol and sterol, so it is known as a new "healthy oil" and "healthy nutritional oil".
8. Soybean oil
Soybean oil is dark in color and has a special bean smell; Thermal stability is poor, and more foam will be produced when heated. Soybean oil contains more flax oleic acid, which is easy to oxidize and deteriorate, resulting in "beany smell". In terms of edible quality, soybean oil is not as good as sesame oil, sunflower oil and peanut oil.
In terms of nutritional value, soybean oil contains 7- 10% palmitic acid, 2-5% stearic acid, 1-3% arachidic acid, 22-30% oleic acid, 50-60% linoleic acid and 5-9% linolenic acid. Soybean oil has a good fatty acid composition and is rich in linoleic acid, which can significantly reduce the serum cholesterol content and prevent cardiovascular diseases. Soybean also contains a lot of vitamin E, vitamin D and rich lecithin, which is very beneficial to human health. In addition, the human body's digestion and absorption rate of soybean oil is as high as 98%, so soybean oil is also an excellent edible oil with high nutritional value.
Edible oil-"symptomatic" purchase
Starting from 10 and 1 this year, the mandatory national standards for peanut oil and soybean oil will be formally implemented. The new standard clearly puts forward the requirements for the source of raw materials and the identification of processing technology, which undoubtedly makes the public pay more attention to the quality and nutrition of edible oil. Recently, the reporter visited the relevant experts of Shanghai Nutrition Society and Dietotherapy Research Association. They believe that when buying edible oil, besides considering the brand, taste and price, there is also a "symptomatic" knowledge.
Soybean oil reduces the risk of heart disease.
Soybean oil contains linolenic acid which can lower blood pressure, and does not contain cholesterol. Clinical nutrition experiments have confirmed that besides high cholesterol, the other two risk factors of coronary heart disease are hypertension and vascular embolism. The composition of soybean oil can just reduce these two factors, which can significantly reduce the blood cholesterol of healthy adults and effectively reduce the risk of coronary heart disease.
Corn germ oil can inhibit cardiovascular diseases.
Hyperlipidemia is the main cause of cardiovascular diseases, and maintaining human fat at a normal level is an important means to prevent cardiovascular diseases. In addition to doing more outdoor exercise or eating more vegetables and fruits, corn germ oil is a kind of vegetable oil rich in unsaturated fatty acids, which can effectively control the blood lipid level and thus achieve the purpose of inhibiting cardiovascular diseases.
Raw olive oil helps digestion and absorption.
Primary olive oil contains unsaturated fatty acids and has strong antioxidant capacity. Rich oleic acid can enhance the contractility of gastrointestinal tract, improve the secretion function of pancreas, liver and gallbladder, protect intestinal mucosa, make food well absorbed in gastrointestinal tract and relieve constipation caused by various reasons.
Sunflower seed oil helps to prevent skin diseases.
Sunflower seed oil is a low-fat oil, in which linoleic acid content is as high as 66%, which is much higher than other oils on the market. In addition, sunflower seed oil also contains lecithin and carotene, but does not contain harmful substances such as erucic acid and cholesterol. Long-term consumption can prevent dermatosis, bronchiectasis and night blindness, lower human blood pressure and lower serum cholesterol.
Peanut oil lowers blood total cholesterol
Oleic acid contained in peanut oil can reduce blood total cholesterol and harmful cholesterol, but it can't reduce beneficial cholesterol. Oleic acid is called safe fatty acid in the field of nutrition, which can effectively prevent cardiovascular diseases. Compared with the basic diet, the peanut oil diet rich in oleic acid and peanut oil plus peanut diet, like the low-fat diet, both reduced the total cholesterol and harmful cholesterol.

Cooking oil should not be stored for a long time.
Many housewives like to buy large-capacity barrels of cooking oil, thinking that they can save worry. If the family has a large population and the oil is used quickly, this is a good idea. However, if the family has a small population and the oil is used slowly, it is not cost-effective to buy a large barrel of cooking oil, because cooking oil cannot be preserved for long.
Cooking oil is easy to deteriorate, because oil will automatically oxidize. The oxidation of oil will produce a lot of toxic oxidative decomposition substances. If people eat deteriorated oil for a long time, it will cause cell failure and induce many diseases. Peroxide formed after oil oxidation will cause rancidity and produce unpleasant smell. The rancidity of oil is not as easy to attract people's attention as the corruption and mildew of food. When we smell the peculiar smell, the hydrogen peroxide content of engine oil has greatly exceeded the national standard value.
Therefore, in order to avoid the deterioration of edible oil, consumers are advised to buy small-capacity barrel oil.
Blended oil will be forced to show the formula "card"
If the national standard for edible blended oil is really promulgated and implemented, all kinds of blended oils currently on the market should not only indicate the edible raw materials on the trademarks, but also remind consumers of the proportion of various raw materials. Yesterday, the reporter learned from the Provincial Quality Supervision Bureau that the draft national standard for blended oil has not yet arrived. According to reports, after soliciting opinions and revisions, the national standard for blended oil is expected to be introduced before the end of the year.
Blended oil must be marked with the content of raw materials.
It is understood that the national standard of blended oil is most concerned about indicating the product formula and proportion, and the packaging label should indicate the percentage of peanut oil, rapeseed oil, soybean oil, linseed oil, sesame oil and corn oil in the total content of blended oil. In addition, the names and contents of other components in the blended oil must be indicated.
The brewing and drafting of the national standard for blended oil took two years. Due to the lack of national standards, the blended oil market is chaotic, which is the so-called "blended oil". Not only are the edible raw materials very different, but the price gap is also very large, so it is difficult for consumers to avoid misunderstanding when buying blended oil.
The price of blending oil varies greatly.
It is understood that blending oil is called high blending oil, which is an edible oil made by blending more than two kinds of refined oils (except seasoning oil) in proportion according to the needs of use. Generally, refined soybean oil, rapeseed oil, peanut oil, sunflower oil and cottonseed oil are the main raw materials.
Yesterday, the reporter visited some supermarkets in the provincial capital and found that there are many kinds of blending oils. In a large supermarket, sales staff told reporters that consumers buy mostly concentrated peanut blended oil and soybean blended oil. The reporter saw that all brands of blended oils only indicated the purpose of raw materials in terms of raw material labeling, and did not indicate the formula ratio.
Because of different raw materials, the price gap of blended oil is also very large. For example, the blended oil launched by a brand, the main raw materials are sunflower seed oil, peanut oil, sesame oil and olive oil, and the price of 5 liters is 76 yuan; Another brand of rapeseed blending oil with the same capacity, the price is only 37 yuan.
The new national standard helps consumers understand consumption clearly.
It is understood that the price of raw materials determines the price of various blended oils. Tea seed oil and peanut oil are more expensive, while others are relatively cheap. For example, the price of peanut blended oil in the current market is above 30 yuan, which usually does not exceed 20%.
It is reported that after the implementation of the national standard of blended oil, the existing terms such as "peanut blended oil" and "soybean blended oil" will disappear, and more than two kinds of traditional oils and fats will be collectively called "edible blended oil". The labeling of ingredients and content, including the source of ingredients, whether it is squeezing or leaching, helps consumers to clearly buy blended oil.
interconnection
How to distinguish the quality of edible oil
It is actually very simple for ordinary consumers to distinguish the quality of vegetable oil. First, smell it. Drop a drop of oil into your palm. After a few laps, smell it. Qualified oil will have the smell of plants, and unqualified oil will have a strange smell. Second, after buying back the vegetable oil, put it in the refrigerator and see if it freezes after half an hour. If so, it is likely to contain inferior palm oil. Third, with the naked eye, oil with normal quality should be completely transparent. If the oil contains alkaline fat, lipid, wax, etc. And the water content is high, and the oil sample will be turbid or precipitated.
