How and when is tea oil harvested? How long can tea oil last?

Is it better to put tea oil for as long as possible?

Whether the longer the tea oil is put for the better, mainly depends on the type of tea oil.

If it is edible tea oil, the fresher the better, if the expired tea oil can be used for skin care, the longer the old tea oil will be, the better the acid value of the old tea oil.

Increased, weakly acidic, and the human body is weakly acidic, the acid-base environment is consistent, it is more absorbent and utilized.

Will the tea oil expire after a long time?

The shelf life of camellia oil.

The national standard is 18 months, which shows that it has expired after this time.

Therefore, the tea oil must have passed the expiration date after a long time, and the expired tea oil not only does not have the fragrance of tea oil, but also tastes very tasty and has a sour taste. However, we can use it as a medicine, which can not only lighten acne scars, but also remove redness and swelling.

Can you eat tea oil after a long time?

Whether the tea oil can be eaten for a long time mainly depends on whether it is not within the shelf life, the shelf life of tea oil is generally one and a half years, and if it is past this period, it cannot be eaten.

As we all know, the food sold on the market has a shelf life, tea oil is no exception, under normal circumstances, in a good preservation environment, the shelf life of tea oil can reach about 2 years, there are some folk sayings that the longer the tea oil is put, the better, in fact, it is not, the quality of tea oil can not be measured by the length of storage, food should not be put for a long time, it is best to eat as much as you buy, as soon as possible.

Generally speaking, tea oil can be stored for a period of time, it is similar to our normal vegetable oil, but it must be at a relative ambient temperature and humidity. Generally, it can be left for about a year.

The shelf life of camellia oil at room temperature can be as long as two years.

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).

Because camellia oil has a large amount of antioxidants, it can have a shelf life of up to two years at room temperature, which is much longer than that of ordinary cooking oil.

How long can tea oil last? I think tea oil can sit for months. As long as you keep it in a place protected from light and not damp. Constant temperature in the room. It can be left for a few months.

If the tea oil is squeezed by yourself, the time is very short, and it is easy to go rancid, if there is a certain amount of purification or preservative, it can be put for a year.

For this kind of tea oil, its shelf life is one and a half years, if the time is too long, it will also deteriorate, so it should be completed within the shelf life and used up.

It is useful to seal it and keep it for several years, and tea oil is the same as honey, the longer the better.

The shelf life of tea oil is very long, as long as it does not have a special taste.

Don't be more than a year old.

After all the tea is picked, it is time to dry the tea. The sun temperature in autumn is generally not as strong as in summer, so the tea should be dried well.

A few days to do it. Spread out the freshly picked tea balls, and after a while, small insects will crawl out.

After a few days of sunbathing, the tea shell will crack, and then the black tea kernel will be removed. Not all tea shells will crack, so you still have to.

Manually selected, and then screened by windmills, the rest is round or oblate tea seeds.

The tea seeds can be fully dried before the oil can be extracted. 100 catties of tea balls can get about 30 catties of tea seeds, and 100 catties of good tea seeds can be squeezed for about 20 catties of oil.

Of course, tea seed husk is also a good thing, it is a good natural fertilizer, and people in the countryside can burn it to ash to make alkali, which can be used to pickle salted eggs, and it can also be used.

Isaac used fertilizer in his garden.

The tea cake after oil is also a treasure, and when there was no shampoo before, women used it to wash their hair and hair, and they could also use it to wash clothes and kill insects.

Wait. The ** of camellia oil is generally high. Cheap is not good, good is not cheap, according to the normal pressing process, the first oil produced.

The cost is calculated (according to the ** calculation of this year's tea seeds) a pound of tea seeds is about 8 yuan, a pound is about two taels of oil, and the cost of a pound of oil is not labor.

The management fee is about 40 yuan, and the market price of packaging is about 70 yuan.

How to buy tea oil?

1.3. Don't buy no products (except for the farmer's own squeeze, which is a good thing that is hard to find now.) )

2.The camellia oil produced by the manufacturer is labeled pressed oil and it is difficult to distinguish, mainly to see (**, color, smell), **too low, no color, no tea oil.

Smell, it is recommended not to buy, of course, if it is used externally as skin care products.

Camellia oleifera sowing time is poor.

Camellia oleifera varieties are divided into common Camellia oleifera, C. oleifera and Camellia oleifera from Vietnam, which are mainly distributed in Zhejiang, Sichuan, Guangxi and other places, and have the largest planting area in China. Sowing date: The sowing date of Camellia oleifera seeds is month.

The climatic conditions at this time are very suitable for the growth habits of Camellia oleifera, which can germinate and grow faster.

Potted Camellia oleifera sowing time.

The best sowing time for potted Camellia oleifera seeds is from February to May every year. The seeds sown during this round period have the highest germination rate and the best growth.

Camellia oleifera sowing temperature.

Camellia oleifera suitable for sowing temperature of 14-21 degrees. When preserving Camellia oleifera seeds, do not expose to the sun, do not pile up seeds, and spread them in a dry and ventilated place, which is conducive to the survival rate of Camellia oleifera seeds.

Camellia oleifera sowing method.

When planting Camellia oleifera seeds with good quality and abundant grains, we should choose land with sufficient sunshine and good drainage system for sowing. Arrange weeding, fertilizing, watering in advance. The sowing depth is kept at about 2 3 cm.

Camellia oleifera is sown and germinated.

Camellia oleifera seeds are soaked in warm water to accelerate germination. They need to be soaked in warm water before cultivating. Camellia oleifera can absorb enough water, so the germination rate will increase, the survival rate will increase, and the sowing will be better.

Camellia oleifera seedlings are sown.

Camellia oleifera seeds emerge about 6 to 8 days after sowing. When planting Camellia oleifera seeds, choose a suitable cultivation environment, give enough nutrients to the virtual cavity shed, and meet the growth requirements of Camellia oleifera, and they will emerge at normal times.

Answer: The oil content of Camellia oleifera fruit reaches the highest value during the frost period, and the oil quality is also the best, which is the most ideal picking period. Moreover, it is generally required to grasp the "first three and seven after the harvest is suitable", that is, the picking starts three or four days before the frost falls, and it is most suitable to pick seven or eight days after the frost.

However, at the same time, the picking period should be grasped according to the ripening characteristics of Camellia oleifera fruit. For example, the fur of rape fruit is exhausted, and the skin of the fruit is shiny, which has become the inherent color of its variety. The kernel is plump, black or brown, hard and shiny, and if the shell of the camellia fruit has become thin and slightly cracked, it indicates that the camellia fruit has reached full ripeness.

At this time, it is necessary to pick and harvest in time.

Reason: Camellia oleifera has a bumper harvest, and timely picking is the key. "Seven bulges, eight oils".

Before the frost fell, the oil rested on the trees." "One more day after the frost festival, one more drop of tea oil on the tree." These proverbs are enough to show that the oil transformation and accumulation of Camellia oleifera fruit begins in early August.

And gradually until the frost falls before and after the kernel basically reaches full ripeness. Therefore, the oil content of Camellia oleifera fruit reaches the highest value during the frost period, and the oil quality is also the best, which is the most ideal picking period. Therefore, the people in the Camellia oleifera producing areas have the experience of "early cold dew, late winter, and frost harvest at the right time" for picking Camellia oleifera.

If it is picked too early, not only will its yield and oil yield be greatly reduced, but the quality of the tea oil will also be greatly inferior. If the harvest is too late, the camellia fruit will naturally crack, and the kernels will be scattered and difficult to pick, which will also reduce the yield and affect the quality.

Camellia oleifera fruits should be picked in a timely manner, and "three observations" should be achieved.

One is to observe the variety. Different varieties have different ripening periods of Camellia oleifera fruits. The crown of "cold dew seeds" is small, erect, the branch angle is less than 30 degrees, the leaves are small and dense, the fruit is small and thin, and each fruit seed is 1 3 grains, which should be ripe and picked at the time of "cold dew".

The canopy of "frost seeds" is larger, the opening branch angle is generally 40 60 degrees, the leaves are large and slightly thicker, the fruit is large, each fruit seed is 4 7 grains, and it should be ripe and picked at the time of "frost fall". "Lidong seeds" have a large crown, an opening branch angle of more than 40 degrees, large and thin leaves, large fruits, 7 10 seeds per fruit, and should be ripe and picked at the time of "Lidong".

The second is to observe the color. In the ripening season of Camellia oleifera, carefully observe the color of tea seeds. The surface characteristics of Camellia oleifera fruit ripeness are:

The peel is shiny, the red peel is red with yellow, the green peel is green with white, the hair on the peel is exhausted, and the tea fruit is slightly cracked and easy to peel. When you go to the Camellia oleifera forest to pick the cones and peel them, when you find that the tea seeds are shiny, peel them off further, and see that the seeds are white and yellow, and when the oil is shiny, it proves that the cones are fully ripe, and you can pick them at this time.

The third is to observe the landform. Camellia oleifera is located in different geographical locations, and the maturity is also inconsistent, generally it is ripe first in high mountains and later in low mountains; The sunny slope is ripe first, and the shady slope is ripened later; The old forest matures first, and the young forest matures later; The barren land is ripened first, and the cultivated land is ripened later.

In the cold dew festival, the oil yield is high, the cones are not ripe, the oil content of tea seeds is low, and the water content is high.
