The blending of oil during cooking will not only maintain the fresh taste and nutritional value of food, but also shorten the cooking time of food and improve the color of food.
The Zhou Li Tianguan Tsukasa Zai records: "All birds are offered: spring lambs, meal cream incense; summer line fish, meal cream; autumn row calf, food paste fishy; winter line fresh feathers, food paste." ”
It can be seen that in ancient times, people have begun to use different birds and animals to make animal oil and cook.
There is also a bird today that sounds like grease, is larger, has a fan-shaped tail, has a particularly small foot, and has many white spots on its body.
Its fat and rounded body looks like a ball of meat from a distance, it was once the "exclusive" grease of the Indians, and it was even called "walking oil bag", it is the owl, the oil owl of the oil owl family.
<h1 class="pgc-h-arrow-right" data-track="6" > will be fat as a vegetarian</h1>
As an important source of long-term oil for Indians, what is the reason why the bird is full of rich oil?
Through reading the relevant information, it is found that the oil owl is not a carnivore, but a vegetarian animal, and most of their diets are fruits and other foods.
According to common sense, birds are generally small in order to be able to fly, but the size of the oil owl is very large, this is because although the oil owl will fly for a long time at night, but their main activity is to find food, after a night of foraging, they will go directly to their burrows to rest for a whole day.
In addition, since they have no natural enemies, they do not need to carry out a lot of movement to escape the pursuit of natural enemies, which makes them greatly lack movement, which further leads to the accumulation of fat.
The fruit eaten by the oil bird contains a lot of fat is also an important reason for their obesity, and the three major types of fruits that the bird often eats are: Lauraceae, Palm family, and olive fruit. The laurenous avocado contains a lot of fat, the fat content of avocado is about 15%, and the fat content of most fruits is basically not more than 1%.
Some people say that avocados also have the effect of losing weight, so why do birds gain fat?
In the process of looking for food, the oil bird will forage for a large number of avocados, and excessive consumption makes the avocado heat accumulation in the bird's body, which in turn makes the bird's body fat. In addition, palm palm fruits and olive olives are foods with high calories and high fats.
In summary, the reason why the oily bird eats vegetarian but fat flowing oil is that while they lack exercise, they forage for a large number of fruits containing oil, and after a long period of accumulation, all of this fat accumulates under its skin, making it a ball of meat wrapped in feathers.
<h1 class="pgc-h-arrow-right" data-track="15" > the "oil pack" being targeted</h1>
The Indians found that at some stage of the growth of the oily bird, the young bird was not only larger than its parents in terms of body size, but also had a higher oil content than the adult bird.
The commonality of the young is that it is not lethal and is not good at flying, so it is more convenient for Indians to catch.
The oil refined by the oil bird has no specific taste and color, and after a long period of placement, the oil will not deteriorate and can be stored for a long time.
The oil extracted by the oil bird is not limited to cooking food, but can also be used as a modern light bulb lighting. This may also be one of the important factors in their use to refine oils and fats.
The oil extracted by an adult oil bird can be used by a small family for a long time, so every year the Indians will carry out large-scale oil refining for catching birds, directly arranging refining tools at the mouth of the oil bird cave, and refining the oil on the spot after catching.
Sometimes even indians would tie the carcass of the oil bird to the top of the stick as fuel for simplicity, and light it directly for illumination.
However, catching the oil bird is not without difficulty, catching the oil bird sometimes needs to go to the cave where the oil bird lives, the oil bird in addition to the "walking oil bag", there is a terrible nickname called "devil", because it often makes some up to 100 decibels of calls, according to the standard of normal human hearing, 100 to 120 decibels of sound is intolerable to people.
This is far higher than the comfort range of human hearing, making people feel very harsh, making people very unbearable, in Spanish, the original meaning of the bird is "howling", which can be said to be very close to its characteristics.
Scientists Griffin and Phelps have conducted relevant research on oily owl and found that the oily owl relies on sound to determine the position of food and obstacles, the same principle as bats avoid obstacles, but the sound frequencies emitted by the two are two extremes.
Because the ultrasonic waves of bats are not heard by people, but the sound of oily birds can be heard by the human ear, and the decibels of sound are almost all more than 100 decibels, it is very likely that the ears of the catcher will be greatly damaged, and even deaf.
However, despite the danger of deafness, the Indians also caught juvenile oily birds in the iguana cave for a long time, refining oil for their living needs.
<h1 class="pgc-h-arrow-right" data-track="27" > oily partridge that does not "crash"</h1>
The oily duck lives in a dim and dull cave, but can discern the direction of it, and this special skill has aroused the curiosity of scientists, so in 1799 German naturalists came here to explore.
After the research of scientists, it was found that the oil owl will make a sharp call when flying in the dark, and judge the position of the same kind and obstacles through the echo, so as not to "crash", so it has a new title of "bird with radar".
The discovery of this echo positioning of the oil bird also reflects that it has great scientific research value in scientific research, making it attract people's attention.
At the same time, this also attracts thousands of tourists to the Oily Bird Park to see this "bird with radar", and gradually the oily bird is listed as a protected animal, avoiding the extinction of this species.
< h1 class="pgc-h-arrow-right" data-track="32" > conclusion</h1>
However, due to the relatively backward primitive capture method adopted by the Indians, using sticks and other sticks to directly poke down the nest, a large number of juvenile oily owl were caught, so that the number of owl was greatly reduced, resulting in great harm to the population of the oil owl.
As a result, the prohibition of the killing of oil birds for oil refining has gradually become a consensus.
Nowadays, the iguana is no longer hunted as a living fuel oil in people's lives, and the owl has been included in the scope of legal protection in many countries, such as the Venezuelan government, with the help of scientific research teams, has established a national park in the Cabri Caves.
More and more conservation measures are being used to protect special species like the oil plover. The use of ostrich refining, a special traditional oil-making method, will gradually become a thing of the past in the future.
