Can you still eat unopened cooking oil after it expires?

Consuming expired cooking oil can be harmful to the human body.

Edible oil, like other foods, also has a shelf life, and the most feared thing about edible oil is oxidation, rancidity, and the formation of hala flavor. 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.

Therefore, whether it is opened or unopened, do not eat edible oil once it expires.

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.

Not edible. Edible oil, like other foods, has a shelf life, and eating expired edible oil will cause harm to the human body. From the outside, the high-quality oil has a moderate color and a light and soft taste, which is made through careful selection of materials and reasonable processing.

On the contrary, the dark color of the oil does not mean that the oil is concentrated, but because of the low degree of refining and many impurities.

When choosing oils and fats, you should also pay attention to their production date and shelf life. Some bottled cooking oils do not have an expiration date, but this does not mean that the cooking oil can be stored indefinitely. Consuming expired edible oil will cause serious harm to the human body, especially the stomach and intestines.

Extended Materials. Expired cooking oil usually causes rancidity and other toxic substances, such as peroxides, during the rancidity process. After rancidity of oil, the smoke is large and choking when heated, which contains decomposition products such as epoxy propionaldehyde, etc., which are easy to be poisoned after eating, so that patients have acute respiratory and circulatory failure.

Food that has passed its expiration date must never be re-sold.

Food that has passed its expiration date can no longer be sold and must be removed from the shelves. But food that has passed its expiration date is not the same as harmful food; The main change in some foods is the deterioration of sensory quality, such as certain fruit juices, beverages and some dry food cereal products with low fat content.

It may also be that the impact of product quality is not very large, but after the best quality period, it can be downgraded to feed. After the expiration date, some foods may lead to potential safety hazards, such as excessive microorganisms, heavy metals, and peroxide values, such as some refrigerated foods, metal canned foods, fried foods, etc.

After the food beyond the shelf life**, it is generally disposed of in two forms: one is incinerated and destroyed or discarded as garbage; Second, it is processed into feed and used as fertilizer for recycling.

Therefore, experts suggest that a reasonable shelf life for food should be formulated on the premise of scientific risk assessment, and enterprises should rely on the technical support of professional institutions to determine the shelf life of products, and verify whether the food can meet product quality and safety standards within the marked shelf life through testing.

At the same time, we should focus on whether the sales link meets the requirements of food storage conditions, comprehensively consider the requirements of production and sales, and formulate a scientific and reasonable shelf life for food. Strengthen the handling of food that has passed the shelf life, and strictly implement the relevant regulations such as destruction. At the same time, it is also recommended that consumers develop the habit of buying food and reading the label to indicate the expiration date, and do not buy and eat food that has passed the expiration date.
