How long does peanut oil sit in a plastic jug

The year is the best state, although it can be eaten for a long time, but this will produce toxic precipitation of aflatoxin.

It's best not to use plastic, my family is poured out of a plastic bucket and put into a clean glass bottle, don't care how much time it can hold, because the time it says means that it is more than that time, people will have problems when they eat it, but it can be determined that it is releasing decomposition toxins little by little from the beginning, chronic poisoning!

The shelf life of peanut oil is related to the moisture and gum content in the oil and the storage conditions.

Generally speaking, hot-rolled peanut oil, after a certain precipitation treatment, is no problem to put in a cool and shady place for 24 months.

Peanut oil is light yellow and transparent, the color is clear, the smell is fragrant, the taste is delicious, and it is a relatively easy to digest edible oil. Peanut oil contains more than 80% unsaturated fatty acids (including oleic acid and linoleic acid. It also contains saturated fatty acids such as palmitic acid, stearic acid and eicosanic acid.

The fatty acid composition of peanut oil is relatively good, which is easy for the human body to digest and absorb.

A family of three in Liugezhuang Town, Haiyang City, was out of danger because they ate peanut oil in raw plastic barrels, which caused food poisoning.

At about 5 p.m. on October 12, 2001, Yi, a villager from Liugezhuang Town, Haiyang City, was looking for something at home when he found a bucket of peanut oil sent by a relative in the spring, so he took it out and asked his wife to cook and eat. The wife noticed that the oil may have gone bad and that it also smelled of plastic.

The husband sniffed it and said, "It's okay, it's not clean, it's not sick." So my wife used peanut oil from a bucket for cooking.

After dinner, Yi's wife and daughter foamed at the mouth, and Yi also felt weak, headache and nausea. So I called ** to the Taoyuan Border Workstation for help.

The doctor said: "Raw plastic barrels cannot store peanut oil for a long time, and long-term storage is prone to chemical reactions, resulting in harmful toxins, and people will be poisoned after eating." ”

1. The general shelf life of edible oil is 18 months, but even if it reaches 18 months, it does not necessarily deteriorate. If the cooking oil is spoiled, you can smell it by smelling it. The shelf life is not certain, because of the different temperatures, the different raw materials used for the oil, and the different containers, so the shelf life will not be the same, if the oil you buy will eat for a long time, it is recommended not to use the original Shuo material barrel, pour it into a glass bottle after buying, it will double the shelf life, and it doesn't matter if you have two years.

2. In fact, the shelf life indicated on the outer packaging is the shelf life in the theoretical sense, that is, the shelf life of closed storage under specific storage conditions. After consumers buy edible oil home, once opened, some nutrients in the oil will be in "close contact" with the air, and a slow chemical reaction will occur, and then produce substances harmful to the human body, resulting in the edible oil within the "shelf life" is not completely "guaranteed".

3. The shelf life of edible oil is generally 18 months, especially after the opening of the barrel of edible oil, it is often difficult to "keep fresh" for 1 month, so it is obviously inappropriate to hoard a large amount, so the edible oil must pay attention to the shelf life, and the edible oil that is expired or turbid, precipitated or has a "hala smell" shall not be edible. When choosing a "big drop" cooking oil, you also have to pay attention to the exact production time of the product.

Generally, the storage time of edible oil should not exceed three months after opening, so don't put it for too long after opening, you have been put it for four years, and you must not eat it!

It's best not to eat any more;

The unsaturated fatty acids in peanut oil are easy to oxidize, and there will be a hala taste after oxidation, and the taste will also have a bitter taste, which is not good for the body when eaten; If you smell it casually, you may not be able to smell the difference, and for the sake of insurance, you can try the sales volume and then use it.

Yes, as long as the plastic bucket itself doesn't smell! Because peanut oil will absorb the flavor.

If you are particular, you will not eat, and if you are not particular, you will eat!

If the surroundings are good and well preserved, a few months is no problem.

Dr. Liu Fafang of the Chinese Cereals and Oils Society pointed out: "Just like water will freeze at 0 degrees Celsius, liquid vegetable oil will solidify after the storage temperature is lower than a certain point, and any pure liquid vegetable oil will naturally solidify when the storage temperature is lower than the freezing point, and even if it is the same oil, due to different production batches or different degrees of temperature changes, the degree of solidification or turbidity is also different, which does not mean that the quality of the oil is problematic." The freezing point of extra virgin palm oil, olive oil and peanut oil is about 5 degrees Celsius, ordinary soybean oil is minus 8 degrees Celsius, and blended oil mostly has a freezing point of 2-13 degrees Celsius depending on the ingredients.

Experts also pointed out that edible oil is not as clear and transparent as possible at low temperatures, and pure virgin edible oil is the focus we should choose. The quality of the oil does not change if it is solidified, as long as it is properly heated, it can be melted naturally, and the oil can be placed next to the heating or hot water at 40-60 degrees Celsius to melt naturally. For ease of use, if the cooking oil is placed at room temperature above 15 degrees Celsius, it will not condense.

Hello! I think that the fried oil is very pure, but there is no factory industrial processing is more scientific and hygienic, their production environment of temperature, humidity, light and sediment are all stipulated by the national hard standards, what is controlled is very strict. So it's clearer and easier to store.

But it's not easy to do it at home.

If the peanut oil has been squeezed at home, the sediment in it may be the granular debris produced by the peanuts during the pressing process, etc., which basically does not affect the quality very much. If you want to remove the sediment inside, you need to filter it with a sand cloth. But I think it's very troublesome, the effect of making it yourself is not big, and the fine gauze oil is difficult to filter, because of the problem of specific gravity, but the coarse gauze can not filter out the sediment.

But it won't be saved for too long. After a long time, there is one"Hara", so eat it as soon as possible, and if there is too much, share it with relatives and friends.

You can also put the peanut oil in the pot to heat and sterilize, and cook it until it just smokes, so that you don't have to worry about spoiling.

Peanut oil must be squeezed by yourself, and if you make homemade peanut oil, the general storage time is about a year, so you don't have to worry about this, you should be able to eat it after a year. And this oil is not easy to break.

The peanut oil we eat at home is squeezed by ourselves, and the shelf life of this peanut oil is still very long.

Self-pressed peanut oil should be preserved, and there is no problem with leaving it for half a year, right? However, it is still necessary to use it as soon as possible to prevent spoilage and expiration.

Generally speaking, if self-pressed peanut oil is sealed and stored well, it can be stored for about three years.

However, if the peanut oil has been opened, or if other substances have penetrated into it, it may cause the peanut oil to deteriorate.

Therefore, it is recommended that you store them separately, separate two jars for those that need to be eaten recently and those that need to be preserved, and seal them if they don't need to eat them for the time being, or put them in the refrigerator for a longer period of time. In this way, there will be no waste.

There is no problem in putting it in the tank for a year or two, and my family has to squeeze peanut oil by itself every year.
