Taking advantage of a wind called "oil poison", everyone's self-squeezed oil has become a "potential cancer killer" for a while, as if any family wants to eat a bite of boiled fish must first pass the test.
However, after a series of field experiments, experts found that the self-pressed oil from the rural snack to the big one not only does not contain carcinogens, but also contains up to 96.9% unsaturated fatty acids, which is not only healthy, but also a particularly good oil for the heart.
Why are experts so dissatisfied with self-pressed oil?
How did self-pressed oil go from delicious to carcinogen step by step?
Our dietary structure is so stubborn that we insist on staying away from self-pressed oil?
Self-pressed oil is still irreplaceable for traditional condiments.
"Oil extraction is a traditional craft in the countryside, we grew up here, and the way of oil extraction was also learned from our parents' generation, so the preservation of this craft is a tradition for us."
The surrounding environment, customs, and even diet will affect people's living habits, so rural people generally have a habit that they have developed since they were young in the countryside: squeezing oil and stir-frying.
The oil extracted here is not vegetable oil produced in the factory, but the result of the multiplication of the oil crops grown by the farmers themselves: oilseeds.
Soybeans, peanuts, rapeseed and even mixed oil extraction are very common in thousands of farming households, and rural people also take advantage of the convenience of growing vegetable oil raw materials from their family gardens to extract their own oil in each family.
As a traditional craft, oil extraction has been recorded as early as ancient times in the mainland, and there are many corroborations about oil extraction in the classics, especially the oil extraction profile of Chaling is the most typical.
In the countryside, oil extraction is not only a traditional craft, but also a continuation of culture, which has left traces in all aspects of people's daily life.
In the daily diet of farmers, oil extraction is the top priority, whether it is the fragrance of cooking or the salty and umami taste in the fritters, self-pressed oil has been running through the farmers' daily meals.
Although vegetable oil has become popular, in rural areas, self-pressed oil is still commonplace, even if some farmers choose vegetable oil, but self-pressed oil accounts for the majority of consumption in rural areas.
Although vegetable oil is convenient, it is still a little expensive in price, and the taste of cooking is also somewhat different from self-pressed oil.
In many rural households, oil extraction is a daily habit, and in order to ensure that oil is available at home at any time, many farmers will bring some oil back with them.
This habit has also been preserved in the countryside for thousands of years, and even though vegetable oil is getting cheaper and farmers are spending less and less effort on extracting it, self-extraction is still an indispensable part.
The Spring Festival just passed was a good time for farmers to harvest oil, and many rural families harvested the oil crops in their fields before the Chinese New Year, and during the Spring Festival, oil extraction is also a custom.
In farmers' homes, insects and rats will not appear at this time, so that the harvest of oil extraction can be maximized, so oil extraction during the Spring Festival has become a custom in many farmers' homes.
In addition, oil extraction also contains a lot of cultural implications, so among farmers, oil extraction has a certain cultural meaning, even if the material level is getting better and better, many people no longer extract oil, but do not extract oil will still grab the oil.
Spring Festival oil extraction has a certain cultural connotation of "festival", some customs, although not the theme of the New Year, but also an indispensable part of the New Year.
In the process of oil extraction, the family goes in and out, some are laying hands, some are putting oil, and some are burning firewood, which has also become a way for the family to reunite in the process of oil extraction.
It is such a harmonious atmosphere that makes people find a harmonious social interaction in the self-extraction of oil, and the family members no longer only meet each other in a meal, but talk harmoniously in the process of oil extraction.
Why self-pressed oil is so strong.
Although the juice is delicious and tastes great, this does not prove that the oil is necessarily reliable.
The family is not only a way to reunite for the New Year, but also a bond to maintain family affection, so many farmers are very attentive when extracting oil, mainly to let their families eat safe oil.
It is precisely because of the fact that farmers are very attentive when extracting oil, so most of the quality of oil extraction is qualified, even if the process of oil extraction is no longer manual, but this point is also worthy of affirmation.
In the process of oil extraction, farmers will use various tools to facilitate the extraction of oil, and also make the quality of the oil more pure and more in line with the taste, which is reflected in the advantages of self-extracted oil.
In the process of oil extraction, the oil is "cleaned", "crushed" and "extracted".
In all three processes, whether using instruments or appliances, there is a certain amount of "cleaning" technology involved.
After the oil is picked, the farmers will "clean" it, because there will be a lot of impurities in the oil, such as sand and stones, so after the oil is picked, the farmers will clean it.
In the process of picking oil, most of the oil will adhere to some dust in the ditch, so in the process of "ground cleaning", the first thing for farmers is to clean and remove the impurities in the picked oil.
Farmers will leave it for a period of time to let the impurities settle on their own, so that the impurities in the oil can be completely removed during the cleaning, and then the impurities in the oil will be "refined" again.
After cleaning the oil, farmers also set it aside for a while to allow the water to evaporate on its own before rolling it, making it easier to roll the oil.
In oil rolling, farmers usually complete the rolling work with the help of water mills, which not only improves the effect of rolling, but also ensures safety in the rolling process.
After the oil is steamed, the farmer will say that it will be left for a period of time, wait for it to be "dehydrated", and then put it into the oil press for oil extraction, so that the water in the oil can be completely removed, and then the oil can be extracted, which can be more smooth.
Such a step-by-step oil extraction technology can make the oil extraction effect cleaner, and at the same time can maximize the removal of impurities in the oil, so in the self-pressed oil, the oil not only tastes better, but also very economical.
In today's oil extraction process, the oil press has become an important tool for many farmers to extract oil, which can improve efficiency and ensure the extraction effect, which is very popular among farmers.
Many villages will have a rented oil press, farmers only need to take their own prepared oil when pressing, and then press the oil, no need to spend a lot of effort, in the speed is relatively fast.
Why is the oil so healthy?
Self-pressed oil is weird, but it's a very healthy juice.
Oil is an essential part of people's daily lives, not only to nourish the human body, but also to provide major nutrients.
The oil is not only rich in fatty acids, but also rich in vitamin E, a substance that protects the body's cells while maintaining the health of the skin.
Oil has an extremely important position in people's daily diet, people in the process of cooking, whether it is frying or frying, are inseparable from the substance of oil, and the oil juice in the dish can also provide important calories for the human body.
When people eat, they can't eat this food, they can easily feel hungry, and at the same time, they can cause many diseases due to malnutrition, so oil plays a pivotal role in people's diet.
Many people choose to give up the intake of oil juice when they lose weight, so some people call oil juice the root of "fat people", but in people's diet, some oil is the real "fat man" oil.
When some oils are repeatedly processed and transformed, they will become "fat man" oil, and the metabolism of this oil in the human body will be relatively slow, which will lead to the appearance of "fat man" in the human body.
After ingestion by the human body, this oil will accumulate in the human body and eventually form fat, and these fats are more familiar to people "fat", so people should try to stay away from this oil in their diet.
Therefore, nowadays, the status of oil in people's diet is slowly decreasing, people will pay attention to hygiene when eating oil juice, and at the same time will pay attention to the selection of oil juice required by the human body.
Therefore, when extracting oil, the oil is extremely rich in nutrients, and also has the fatty acids required by the human body.
The oilseeds in the oil extraction raw materials will not be processed too much in the process of oil extraction, and at the same time, the original nutrients of the oil can be retained, so the extracted oil is rich in more nutrients, which is very important for the human body.
In vegetable oil, there are some unsaturated fatty acids, which are very beneficial to the human body, and the content of unsaturated fatty acids in oil extraction is extremely high, as high as 96.9%.
This substance can dissolve cholesterol in the human body and excrete cholesterol from the body, which can not only have an anti-aging effect, but also clean the human body and make the human body more smooth.
In addition, when extracting oil, the oil will not be heated too much in the process of oil extraction, so that the heat in the oil is not lost, and people can also ingest this part of the calories when eating.
epilogue
The traditional process of oil extraction has a very precious value and an irreplaceable role today.
Although it is strange to press oil, it is the real oil juice that people eat, it is part of the tradition and the beginning of health.
We might as well taste more of this "weird" oil juice, and at the same time enjoy the warmth of people and emotions in it.
