Can I still eat my own tea oil after three years?

If it is well preserved, it should still be edible, and many rural people make their own oil for two or three years.

Your own tea oil is absolutely real and natural, but there may not be a good level of disinfection during the production process, and the preservation is not as good as the sealing technology bought outside, so you can try it, and if you find that it has changed its flavor or looks wrong, don't eat it.

No.

Although camellia oil is the high-end oil in edible oil, the most important point is that it has a high ignition point, so it is very suitable for stir-frying and fried food. Its shelf life is generally 18 months, and camellia oil that has been left for 10 years cannot be used, because oil products will produce carcinogens such as aflatoxin if left for too long. So everyone should pay attention.

Tea oil that has been left for 10 years can no longer be consumed, and it should be applied with caution externally. The state stipulates that the shelf life of tea oil is 18 months, and the opened tea oil should be consumed within 3 months. If the oil is left out for too long, it will become rancid and may be contaminated with Aspergillus flavus, producing aflatoxins.

Rancidity of fats and fats will produce a hala taste, which not only loses its original taste and corresponding nutritional value, but also may cause nausea, vomiting, abdominal pain, diarrhea and other symptoms after eating. Aflatoxins are carcinogens and are a serious threat to human health if contaminated with Aspergillus flavus. Although expired tea oil cannot act on the human body, it can be used in other places, such as lubricating mechanical switches, moisturizing and gluing rubber shoes.

How to preserve camellia oil:

Camellia oil is suitable for sealed storage in a cool and dry place away from light, generally below 25. There will be a small amount of milky white flocculent crystals at low temperatures, which is a normal phenomenon and does not affect consumption, and the external temperature will disappear naturally Because the crude oil in tea oil contains a large number of antioxidants, after dehydration, the shelf life at room temperature can be as long as 2 years, which is much longer than that of general edible oil.

Camellia oil can not be used for 10 years.

Camellia oil can not be stored for ten years, the storage time of tea oil is generally about 18 months, beyond the shelf life is inedible, preservation of tea oil should also pay attention to the method.

The shelf life of tea oil is mostly about 18 months, and there is a longer time of about 2 years, if the shelf life of tea oil is more than 2 years, it is edible, but if it exceeds the shelf life, it is necessary to see whether the tea oil has been oxidized and deteriorated, if there is no oxidation, it should be eaten in time, if it is deteriorated, do not eat it again.

Because tea oil contains a large amount of antioxidants, it is easy to oxidize and deteriorate after opening, so be careful when eating.

Storage:

Camellia oil is suitable for storage in a cool, dry and dark place, with an optimal temperature of 10-25. There will be milky white flocculent crystals at low temperatures, which is a normal phenomenon and does not affect consumption, and will naturally disappear when the outside temperature is high (Note: refined camellia oil will not have this phenomenon after freezing treatment).

Due to the large amount of antioxidants in camellia oil, the shelf life at room temperature can be as long as two years, which is much longer than that of ordinary cooking oil.

After each use, the cap should be tightened to reduce the contact time with air, and the camellia oil should be sealed well, and the cap must be tightly screwed to make it tightly sealed. Moreover, the number of times the lid is opened should also be minimized, so that the camellia oil does not come into contact with the air too much and oxidize.

Of course, you can't eat it, especially if it's been left for more than 2 years.

1.Tea oil will deteriorate and even be oxidized after a long time. Some harmful substances are produced, which endanger their own body. We can have other uses, such as emollients, and it is okay to use them to apply to the body.

2.Because tea oil contains a lot of antioxidants, it can be stored at room temperature for 2 years. In addition, the deterioration of tea oil can also breed a large number of bacteria, and even damage the human body.

If it damages the gastrointestinal tract, it causes abdominal pain and diarrhea. In addition, the linoleic acid component in it reacts with the oxygen in the air, causing oil oxidation. It is likely to trigger food poisoning.

3.At the same time, it contains antioxidants and vitamin E, which can be used as a hand cream.

Look at the quality of the tea oil and the storage environment, and how long it lasts. The oil in reserve can be stored for 3 years. In a low temperature, protected from light, low moisture impurities in oil, and sealed environment, the shelf life of tea oil can be extended.

However, if there is a lot of light, high temperature, impurities or moisture, oxidation, hydrolysis or rancidity will occur in 1 month, which will be harmful to the body and inedible.

If you have left your own tea oil for three years, it is generally not recommended to continue to consume it.

Generally, the shelf life of most tea oil is around 18 months, if the shelf life is exceeded, the tea oil is likely to be oxidized by the air, and even a peculiar smell will appear.

After opening, it is recommended to take it as soon as possible within a short period of time. If it doesn't run out for a short time and it expires, we can also use it for other purposes, such as smearing the body.

Camellia oil is suitable for sealed storage in a cool and dry place away from light, generally below 25. There will be a small amount of milky white flocculent crystals at low temperatures, which is a normal phenomenon and does not affect consumption, and will disappear naturally when the outside temperature rises.

How to choose camellia oil:

1. Color: Authentic camellia oil must be filtered and refined in the production process, and it is light and dusty yellow in color, and the oil body is clear and translucent without sediment, and if it is a small workshop pressed camellia oil, the color is relatively dark yellow, and the oil body is turbid, which is caused by the fact that it has not been filtered, refined and other processes.

2. Grade: At present, camellia oil is divided into two kinds, one is only the virgin oil that is only taken from the first pressing oak, which is the best quality first-class camellia oil on the market, and the other is leaching oil, which is a multi-pressed oil, and the quality is slightly worse than that of virgin oil.

When it comes to tea oil, everyone must be familiar with it, it is a common edible oil in our lives, because it has the effect of moisturizing the lungs, detoxifying, reducing swelling, relieving pain, and beauty, so it is loved by everyone, but many people have tea oil when eating tea oil can be used for six years.

The national standard for the shelf life of tea oil is 18 months, and it is conceivable that tea oil that has been put for six years must not be eaten.

Camellia oil is the first choice for many families to buy edible oil because of its rich nutrition, the main reason for this is that the oleic acid content of camellia oil is the highest among all vegetable oils, much higher than the oleic acid content of olive oil, and high oleic acid is just the essential nutrition of the human body. In addition, it should be noted that tea oil cannot be left for a long time, and it is recommended that you use it up within 18 months at the earliest.

Tea oil has a long taste, and it is mostly expired, so don't use it like this, but it can be used externally.

Tea oil is generally put into a bottle after being squeezed, usually in a small bottle, and then poured into a large bottle after eating. However, as a tea oil rich in unsaturated fatty acids, it is also easy to be oxidized, and it is a little "carrying" taste, like this, it is best not to eat, you can use it externally for hair care and face washing.

If it is sealed, it will be two years, but it is best to use it up within 3 to 6 months after opening the cap.

Camellia oil said that many families are using edible oil in life, because of the strong antioxidant property of camellia oil, under normal circumstances, the shelf life at room temperature can be as long as two years, which is much longer than the shelf life of general edible oil. After opening, camellia oil can only be stored for 9 months to a year. If it has been opened, it can be consumed in the normal amount, and it will not expire in a short time.

But in order to ensure the quality and freshness of camellia oil, it is best to try to use it up within 3-6 months.
