The shelf life of camellia oil, how long is the shelf life of camellia oil

Camellia oil is rich in nutrients, containing fatty acids (93% unsaturated fatty acids, including 82% oleic acid and 11% linoleic acid), camellia glycosides, tea polyphenols, saponins, tannins, and antioxidants and anti-inflammatory effects of squalene, squalene and flavonoids, which have excellent effects on anti-cancer.

The shelf life at room temperature can be as long as two years, which is much longer than that of ordinary cooking oil.

Camellia oil should be stored in a cool, dry and dark place, with an optimal temperature of 10-25. At low temperatures, there will be milky white flocculent crystals, 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).

Since camellia oil has a large amount of antioxidants.

However, although they are all tea, the shelf life of tea is determined by different varieties, it is recommended that you can book it at the nine products of hospitality, and the annual output of the tea of the nine products of hospitality is very small due to the strict control of quality, and it generally needs to be customized in advance.

The shelf life of camellia oil is 2 years. Camellia oil should be stored 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.

Camellia oil: Camellia oil (also known as wild camellia oil, camellia seed oil, camellia seed oil) Bowang Tong is taken from the seeds of Camellia oleifera in the family Camelliaceae. The production process of camellia oil can be divided into:

Hulling, drying, crushing, steaming, oil extraction, filtration. Tea oil does not contain erucic acid and cholesterol. Tested:

The unsaturated fatty acids in tea oil are as high as more than 90%, oleic acid reaches 80 83%, and linoleic acid reaches 7 13%, especially the rich linoleic acid contained in the Ketan is necessary for the human body and cannot be synthesized.

For the container of camellia oil, you can choose a ceramic cylinder when there is a lot of oil, and try to reduce the diameter of the container, and when the oil is less, you can choose a dark glass bottle that is opaque. After the oil is filled, the bottle mouth should be sealed to isolate the oil from the air and prevent the oxidation and deterioration of the camellia oil.

The container for storing camellia should be placed in a cool, dark, dry place with a low temperature. Because ultraviolet and infrared rays in sunlight can promote the oxidation of grease and accelerate the formation of harmful substances, the oil storage container should minimize the contact with air and sunlight.

Store camellia oil to prevent high temperatures. The storage temperature is best at 10-15 degrees, and generally should not exceed 25 degrees. Therefore, as long as the camellia oil is stored properly in winter, there will not be much of a problem.

The refining method of tea oil.

The pressing method and the leaching method are the two methods of camellia oil extraction. The pressing method is a physical pressing method, so the name suggests that the oil produced by pressing and extruding vigorously, and the oil we buy is pressed out by the machine, this oil is simple in process, low oil yield, and the maximum nutrition is retained, so this oil is a better oil, and it is slightly more expensive.

Because the oil yield of the pressing method is very low, the general business will adopt the above two methods to complement each other, that is, after the camellia seeds are pressed to obtain the "pressed original tea oil", the residual tea oil in the "oil cake" is fully extracted by the leaching method to obtain the "leached original tea oil".

Farmers may roast and steam the tea seeds repeatedly, if the temperature control is not good, it is easy to lead to burning, and benzopyrene is formed, which remains on the shell of the tea seeds; After pressing, all benzopyrene remains in the tea cake, and when the residual oil in the tea cake is extracted, the residual benzopyrene is also extracted in large quantities, and the chemical reaction with the solvent oil occurs at high temperature, which eventually leads to the continuous increase of the benzopyrene content of the crude tea oil after leaching.
