At what temperature can cooking oil be burned to eat?

The temperature at which the cooking oil should be burned should be about 200 degrees, because if you see the oil smoking, it means that it is he.

Edible oil can generally be eaten when it is burned to more than 80 degrees.

It is best not to eat it when stored for a long time.

Edible oil cannot be stored for a long time after heating. The oil commonly used in life is vegetable oil, soybean oil, vegetable oil, peanut oil, etc., the oil is mainly composed of lipoprotein and phospholipid cholesterol components, edible oil after high temperature, the fatty acid linoleic acid will have different degrees of destruction, and the ingredients in the oil will synthesize a toxic substance, after people eat it, it will stagnate in the body, make the liver enlarged, cause liver dysfunction, and the risk of carcinogenicity, although edible oil is unhygienic in the process of processing, but there is pH in the food oil, It is not a place for bacteria to grow, there are very few bacteria in it, and there is no need to store it warmly.

Edible oil after high temperature, where it is heated above 150 degrees after oxidation, so that on the one hand, fatty acids linoleic acid and vitamins are damaged to varying degrees, on the other hand, unsaturated fatty acids, oxygen and later polymerization is easy to occur to constitute macromolecular compounds have a certain toxicity, after use can make animal growth stagnation, liver enlargement, reproductive function and liver function disorders, and may also lead to carcinogenic effects, so edible oil can not be heated and then stored, Although edible oil is susceptible to different degrees of contamination in the process of production and storage, it is unhygienic for direct intake, but from the pH and osmotic pressure of edible oil, it is not an ideal place for bacteria to multiply, even if there are a small number of bacteria, it does not have to be stored after high temperature heating.

Edible oil should not be placed next to the stove, where the high temperature will speed up the oxidation reaction of the oil, which is more likely to rancidity and deteriorate, and will also attract different degrees of oxidation, so that its nutritional value becomes low, and even produces aldehydes and ketones that are harmful to the human body.

It is easy to spoil, so after buying cooking oil. The right storage should be chosen. It can be placed in a high temperature environment.

Nor should it be placed near the stove. High temperatures may result in an accelerated reaction of oxidation. Prone to acidic deterioration.

When vitamin A, vitamin D, and vitamin E are oxidized to varying degrees. The nutritional value will also be reduced. It can even be harmful to the body.

It is recommended to maintain a good diet in daily life. Avoid excessive consumption of foods high in oil, salt and fat. Avoid eating foods that have been left out for too long to avoid causing damage to the body.

It is recommended to keep it in a cool, dry place at ordinary times. In this case, it is better to store in a cool, dry place. In daily life, you can buy less and buy again when you run out.

It's not easy to break this way.

The main nutrients of animal and vegetable oils, such as lard, rapeseed oil, soybean oil, tea oil, sesame oil, peanut oil, etc., are phospholipids, cholesterol and lipoproteins, unsaturated fatty acids, a small amount of fat-soluble vitamins and trace elements. When the oil is heated at a high temperature (above 150 degrees), the oxidation process is accelerated. In this way, on the one hand, essential fatty acids, such as linoleic acid and vitamins, will be destroyed to varying degrees; On the other hand, unsaturated fatty acids can undergo polymerization reactions after oxidation to form macromolecular compounds, which have certain toxicity, and can cause human growth stagnation, liver enlargement, reproductive function and liver function disorders, and even carcinogenic effects after consumption.

Therefore, edible oil should not be stored after heating at high temperatures.

Although edible oil is susceptible to different degrees of pollution in the process of production, transportation and storage, and direct import is unhygienic, it is not an ideal place for bacteria to multiply from the perspective of pH and osmotic pressure of edible oil. Therefore, even if there is a small amount of bacteria, it is not necessary to heat it at high temperatures and store it.

If it is left in high temperature for a long time, it cannot be eaten.

Edible oil cannot be stored at high temperatures, and storage at high temperatures can accelerate the oxidation of edible oil, which is more likely to deteriorate and become sour.

If you open the package, you have to rely on the temperature of the room where you live, whether it is exposed to sunlight and whether it is ventilated, and the sooner you eat it after the lid is opened, the better.

Under normal living conditions, edible oil without added antioxidants will generally reach the critical point of deterioration after 2 months of opening. After a few days, the characteristic "hala smell" of rancidity will appear.

Edible oil with added antioxidants can be stored for a longer time after the lid is opened, but there is no research conclusion on how long. In general, it is recommended that everyone eat it within 3 months. It should be noted that most of the edible oils on the market now have added antioxidants, and the commonly used ones are "tert-butylhydroquinone" (TBHQ) and "bht" (BHT).

Attention should be paid to household oils:

Try to buy small packages to shorten the use time after opening the lid; Reduce the number of opening caps, seal them in time after each use, and reduce the chance of contact with air; Keep away from high temperature environments such as stovetops, and store in a cool, dark place. It is important to note that if you find that the oil is rancid, do not continue to consume it. Peroxides and free radicals harmful to the human body will be produced in the process of oil rancidity, which will accelerate human aging and increase the risk of tumors, cardiovascular diseases and other diseases.

The shelf life of edible oil sold on the market is relatively long before it is not opened, usually 18 months, as long as the edible oil bought home is not opened, stored in a dry and cool place, and the shelf life of 18 months can be opened and used.

But if it is edible oil after opening, it is different, generally speaking, 3 months after the edible oil is opened, it is a critical point for safe use of oil, after the opening of the edible oil, it is recommended that you should use it up within 3 months, more than 3 months, rather throw it away than continue to eat.

Because, after opening, the edible oil will be easily affected by the environment, temperature and other aspects, especially many people directly use the big barrel of oil to fry the vegetables, every time you cook, the large barrel of oil is opened and closed again and again, which seems to be a normal practice, but this will make the nature of the oil change, hidden dangers. The edible oil in the barrel is exposed to more oxygen, it is easy to oxidize the reaction, and the nutrition is greatly reduced, not to mention, the degree of oxidation and rancidity of such oil is equivalent to the oil in the range hood box, which is also harmful to human health; Moreover, it is easy to pour too much oil directly when using large barrels of oil, and eating too much oil is also easy to cause obesity.

You can buy small barrels of edible oil, you don't have to worry about oxidation, you can also almost guarantee that you can eat it within 3 months, if you add more members to the family, buy a large barrel of oil back, you may wish to divide it into a small bottle for use.

The shelf life of unopened cooking oil is 18 months when stored in a good environment. After opening, the edible oil will come into contact with the air, and the fatty acids in the oil will change, and the nutritional value will become lower, so the shelf life is shorter than that of unopened edible oil, and it is recommended to consume it within 3 months. Try to store cooking oil in a cool place away from light to avoid deterioration.

After the oil drum is opened, it is poured into the household oil pot, and then the lid is tightened and placed in a cool place, then the shelf life time is about one and a half years. 2.The shelf life of cooking oil used in cooking is about 3-6 months

1.After the edible oil is opened, the oil will be exposed to air and water, etc., resulting in an oxidation process, and the longer it is placed, the higher the oxidation degree of the oil, and finally the oil will deteriorate and rancidity. 2.

It is best to use up the edible oil within 3 months after opening, and the longer the time, it will deteriorate due to excessive oxidation and rancidity of the oil, so it is best not to eat the oil at this time [flowers].

Hello, edible oil can generally be put for about half a year after opening the tiredness, of course, it must be sealed and placed in a cool and dry place, if there is no unopened edible oil can be a year and a half to two years, the edible oil after opening is easy to oxidize rancidity, you can put a grain of vitamin E in it, which can extend the shelf life.

I hope the above content is helpful to you in your life, and I wish you a happy life!

All have a shelf life, and the shelf life of edible oil is generally 18 months.

If you look at the shelf life on the top of the jug, most of them are 18 months.

Because the lipids or proteins contained in edible oil will affect human absorption and cause physical discomfort if they are not cooked, and edible oil also contains alkaloids, if the alkaloids are cooked, it will affect the taste of the dish, so the edible oil must be cooked.

Edible oil, also known as "edible oil", refers to animal or vegetable oils and fats used in the preparation of food. It is liquid at room temperature. Due to the raw materials, processing technology and quality, the common edible oils are mostly vegetable oils, including rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, sunflower oil, soybean oil, sesame oil, flaxseed oil (flax oil), grape seed oil, walnut oil, peony seed oil and so on.

For housewives, edible oil is the most common food, usually in the process of stir-frying or frying food need to use edible oil, the general capacity of relatively large edible oil ** will be cheaper, many people in order to be cheap will often buy very large capacity of edible oil, but after opening but not how to use, therefore, these edible oil may be stored for a long time, but the use of oil after opening is easy to be polluted by dust, oxides, bacteria in the air and cause problems with the quality of edible oil, If the oil is used and has not been opened, the general storage time is 18 months.

If the use of oil has been opened, it is easy to be affected by many factors to cause changes in the edible oil itself, therefore, it is best not to use the edible oil for more than three months after opening, and it is best to use it within three months, so that it will not be interfered with by oxidation or other undesirable factors to reduce its nutritional value, otherwise the regular intake of edible oil that has been opened for too long may bring some negative effects.

How long should I not continue to eat cooking oil?

Edible oil is not said to be used for a long time, if it is better not to use it for more than three months, many people do not pay attention to this problem, edible oil is not stored well after opening, and the long-term influence of oxidizing substances in the air will lead to a decrease in its nutritional value, if it is not used for more than three months, the remaining edible oil is best thrown away, otherwise do not pay attention to the health of the diet, and often ingest these oxidized edible oils, which may have a negative impact, In this way, it is impossible to obtain the nutrients inside to promote good health.

What are the benefits of proper intake of cooking oil?

Proper use of edible oil can also promote good health, many people think that edible oil has a lot of oil, so it should not be ingested, in fact, oil is also one of the nutrients needed by the human body, but it is not possible to consume a large amount.

If you can choose peanut oil, olive oil, canola oil, etc. to obtain nutrients, it can usually also promote good health, and it also contains unsaturated fatty acids that the body needs. Therefore, it is possible to use these cooking oils appropriately, but it is necessary to control the amount, pay attention to the storage problems, and do not exceed the limit of use.

Usually, the shelf life of edible oil can be as long as 18 months in the unopened state. After opening, the edible oil will come into contact with the air, and the fatty acids in the oil will change depending on the storage time, the nutritional value will be reduced, and the shelf life will be shortened, so it is recommended to consume it within 3 months.

The usual storage environment and temperature also determine the shelf life of edible oil. It is recommended to store unopened cooking oil in a cool place away from light, if exposed to high temperature and ultraviolet rays, it will promote the oxidation of fat in the oil, resulting in the deterioration of cooking oil.

Freshly opened cooking oil can be divided into small dark glass bottles to reduce contact with air, and it is not recommended to store it in large plastic barrels, so that the oil will accelerate deterioration. It is not recommended to put the cooking oil near the stove at a high temperature to avoid spoilage.

Generally speaking, if the edible oil is not opened, it is more to be stored for 12 to 18 months, and it is recommended to use it up as soon as possible after opening.

In the case of sealing, it can generally be left for 6 to 8 months. If it is in the case of exposure, it is generally not more than a month.

The oil purchased in the supermarket has a shelf life, if you boil the lard yourself, look at the storage method, you can eat it for a year if you store it!

Edible oil can be stored for a year without opening, but if it is opened, it is best to eat it within half a year, so as to ensure the quality of the oil and make the body healthy.

The boiling point of edible oil is generally above 200, of which the boiling point of peanut oil and rapeseed oil is 335, and the boiling point of bean oil is 230.

Cooking oil can give dishes a tender or crispy appearance. In the cooking process, the use of grease as a heat transfer medium is widely used, due to the high ignition point of grease, after heating, it can speed up the cooking speed, shorten the cooking time of food, and keep the raw materials fresh and tender. Proper control of the heating time and the temperature of the oil can also make the dish crispy and crispy, so it is often used in fried dishes.

Oil can be 1 times higher than water or steam, quickly dissipate the moisture on the surface and inside of the raw materials, and the oil molecules penetrate into the inside of the raw materials, so that the dishes exude an attractive aromatic smell, thus improving the flavor of the dishes.
