Can soybean oil be eaten after it has expired for a year?

Soybean oil cannot be eaten after the expiration date. Edible oil can not be eaten after expiration. Edible oil has been stored for a long time, especially the residual crude oil, which contains more plant residues, and the rancidity of oil and fat can occur.

Edible oil contains a linoleic acid component, which is easy to chemically react with oxygen in the air, this phenomenon is called oil oxidation. After the rancidity of the oil, the smoke is large and choking when heated, which contains decomposition products such as epoxypropionaldehyde, which is easy to be poisoned after eating. Expired cooking oil will be oxidized to produce lipid peroxide, which is not only bad for blood vessels, but also carcinogens.

The meaning of shelf life on a food label refers to the date on which the quality of the food is guaranteed under the conditions specified on the label. After the food exceeds the expiration date, although some foods have not deteriorated, but from the perspective of safety, as long as it expires, it can not be eaten, sometimes we can't see the change of ingredients with the naked eye, but the structure inside has changed, or do not eat it. The shelf life is a mandatory rule, which refers to the final date on which the food can be eaten under the labeled conditions.

Extended information: The term shelf life is commonly used on food packaging labels, and it is also the main label information that consumers pay attention to when buying food. Generally speaking, determining the shelf life of food needs to be considered from two aspects, one is the edible quality, such as appearance, color, texture, taste, etc., and the edible quality of the food within the shelf life should not have obvious deterioration, such as:

Bread within the shelf life will not be significantly dry and hard; Another aspect is its hygienic quality. In production practice, most of the microbial indicators are used as the basis for judging its hygienic quality, and the food within the shelf life should not have spoilage caused by microorganisms. However, the "expiration date" is not the same as safety, and after the expiration date, it does not mean that it becomes unsafe, but that the quality is poor.

In fact, the term "expiration date" misleads Chinese consumers. The shelf life of food is determined by the manufacturer according to the situation of the product and after doing the relevant shelf life experiments. In China's national food safety standard "Prepackaged Food Labeling Standards", specific provisions have been made on the shelf life of some foods.

This regulation is the minimum requirement that enterprises must meet, and by improving the process and packaging, the actual labeled shelf life of the products produced by the enterprise can be higher than the national regulations. It can be seen that the labeling of the shelf life is not arbitrary, and many factors must be taken into account. After this period, the quality will change and it will no longer be suitable for consumption, let alone used for **.

It is recommended not to eat expired food, which may be more expensive than medical expenses and buying a new barrel of oil.

Can you still eat soybean oil after it expires? A lot of people don't know yet.

Can soybean oil be eaten after it has expired for a year?Soybean oil has expired for a year, and it must not be edible, and this oil must have moisturized bacteria.

Soybean oil cannot be eaten after it expires. Soybean oil is an edible oil, it has a shelf life like other foods, and eating expired soybean oil is harmful to the human body and may cause poisoning. The plant residue at the bottom of the edible oil is prone to rancidity, and the expired soybean oil has a large oil smoke and a choking taste when heated.

Can soybean oil still be eaten after it expires.

Consumption of expired soybean oil can lead to poisoning.

The linoleic acid component in vegetable oil can react chemically with oxygen in the air to generate small molecule aldehydes, carboxylic acids and other oxides with special odors, so that soybean oil can be oxidized and rancid, and eating may cause poisoning.

Expired soybean oil is smoky.

Expired soybean oil is not recommended to continue to eat, because expired soybean oil will have a very large amount of oil smoke when heated, and it will be very choking, and the fried food will not taste very good. Eating expired soybean oil can be harmful to our gastrointestinal health.

Precautions for buying soybean oil.

When buying soybean oil, be sure to keep an eye on its production date and expiration date to ensure that it is consumed before it expires. If you don't have a lot of oil for daily use and are not willing to buy large barrels of soybean oil, buying small packages of edible oil can better avoid expiration.

Edible oil has a certain shelf life, only within the shelf life can be safe to eat, if the expiration date is not eaten, if the consumption of expired edible oil will cause harm to the body, such as will cause abdominal pain and diarrhea, serious will lead to food poisoning. Not only can edible oil not be used after the expiration date, for all kinds of food, after the expiration date can not be eaten, because the expired food will contain a large number of mold, eating mold food will lead to digestive flora confusion, food poisoning, and even cause acute diarrhea, and even life-threatening.

It is recommended that you do not consume it after the expiration date.

In fact, there is no expiration date, if the soybean oil is well preserved, it can be completely used. If the beans have no pitch change, and are normal in terms of setting and taste, then they can be used.

Most of the specifications of soybean oil are packaged in 5L weight, and if you don't eat it in time, it can easily pass the expiration date. Many people feel sorry if they throw it away, but after eating it, they are worried about the impact on their health. Can soybean oil still be eaten after it expires?

Here is a reminder to moms and friends: after the edible oil has been left for a long time, especially the residue remaining at the bottom of the bottle, it is easy to appear rancidity. Because oils and fats contain an ingredient called linoleic acid, which is prone to chemical reactions with oxygen in the air.

This process is called "oil oxidation", and it is accompanied by reactions such as hydrolysis, which will produce some substances that are harmful to the human body. Especially when heated, the oil smoke is large, the taste is choking, and it is likely to cause poisoning after eating.

Therefore, it is recommended that if you usually use a lot of oil, you can buy small packages of edible oil, and you should look at the production date and expiration date clearly, and eat it within the best consumption period.
