It is said that oil extracted from rural areas cannot be eaten. Is there really a problem?

In the past, there was no barreled oil for sale, and the older generation of farmers all consumed self-pressed oil. If there was really any problem, could it still be spread to this day? Common people have never said that self-pressed oil in rural areas cannot be eaten. Could it be that some experts and professors expressed their opinions in order to attract people's attention.

Rural people have relatively abundant land resources. In autumn and winter, every household will plant some rapeseed. When the rapeseed matures in the second year, the harvested rapeseed will be taken to the town to press oil to meet the needs of the family. Required cooking oil.

How should I put it? The income of farmers is relatively low. It is unrealistic for them to pay high prices to buy barreled oil. A barrel of oil sold in supermarkets costs tens of yuan at least. There is a large population. Some families simply cannot afford it. It is definitely more cost-effective to grow their own rapeseed and then extract the oil later.

Why do some people say that self-pressed oil in rural areas cannot be eaten? The main reason is that they think it is unclean and are afraid that they will get sick after eating it. Just like when some experts said that vegetables watered with manure cannot be eaten, there was a lot of controversy on the Internet, especially among farmers, who opposed such a statement.

After processing, the barreled oil in the supermarket looks better in color, and after being packaged, it looks higher grade, and the price is much higher than that of self-pressed oil. However, this kind of barreled oil has also been squeezed, but it is difficult for consumers to see the entire operation process. No one knows whether it is clean or not. From a health and safety perspective, high-income families in cities will buy barreled oil even if the price is higher, and will not buy bulk cooking oil.

There are all kinds of barreled oils sold on the market. Some of them are branded edible oils, which naturally have a better reputation and guaranteed quality. However, this kind of oil is advertised on major TV stations. How many of these brands are there? It is a household name, and the price sold in the market is higher. There are also some non-branded barreled cooking oils on the market, some of which are produced by small workshops. The quality cannot be guaranteed, and consumers may also buy barreled cooking oil of poor quality.

It can be seen from this that not all barreled cooking oil is better than self-pressed oil in rural areas.

Rural people have been eating self-pressed oil for generations, and have had no major problems for a lifetime. Why do some people still doubt that self-pressed oil cannot be eaten? Mainly because there are certain drawbacks to self-pressing oil in rural areas. Let’s talk about my views below.

First, some people think that self-pressed oil in rural areas is not clean, and worry that it will affect their health.

Now that people’s living conditions have improved, they pay special attention to the health and safety of food ingredients. In recent years, , food-related poisoning incidents are also frequently reported, which has also attracted the attention of ordinary people, especially those who are very concerned about what they eat. As the saying goes, diseases come from the mouth, so food safety is the top priority.

In some cities, food processing industries must have certain qualifications and obtain approval from relevant departments before they can carry out relevant business activities.

But it is different in rural areas. Some small oil-pressing workshops just buy the equipment and start business without the relevant qualifications at all, not even a business license. Every year after the harvest of rapeseed and peanuts, many farmers go to the workshops in the town to press oil. Business is also booming at that time, and farmers almost get up early to queue up there. After the oil pressing is finished, one family will continue to press another. Since the oil pressing workshop is busy during this period, the staff is almost too busy and there is not much time to clean the machine.

The pressed oil has a relatively high concentration, looks a little sticky, and has a darker color, which does not look good. Some people think that the oil pressed in rural areas is not clean. The concentration of barreled oil is not as high as that of pressed oil, but it can guarantee a certain degree of purity. From a nutritional perspective, it is not as good as pressed oil.

Second, the oil pressed in rural areas all uses ancient methods, and the machinery and equipment are relatively backward.

The small oil mills where farmers go to press oil are not highly mechanized, and many processes are It has to be done manually. After all, there is a big difference between a small oil mill and a large factory. If there is no more funds to buy large equipment, the only way to do it is to use the ancient pressing process.

First, the impurities of the rapeseed are removed, and then they are dried, crushed with a rice mill, cooked in a boiler, and then put into an oil press, using a similar method. Use a jack to press it and wrap it into a large round cake. During the pressing process, oil will come out. After the pressing is completed, the impurities in the rapeseed will be rapeseed cake.

Because these equipments are relatively backward and the technology in all aspects is not as good as that of large factories. The pressed oil is not filtered well and contains more impurities. If the purity is not enough, the quality will not meet the standard.

From a technical point of view, self-pressed oil is pressed in small workshops with backward equipment and technology. The quality of the pressed oil is not up to standard, and urban people will think that the pressed oil is unclean. However, farmers believe that although this oil is substandard, it will not affect consumption. They have been doing this for many years, which proves that there is nothing wrong with this oil.

Thirdly, urban people believe that rural pressed oil is a three-no product and contains the risk of toxins

Some experts believe that rural self-pressed oil has not been processed during the production process. The relevant inspections indicate that the products are classified as "three-free" products and may have the risk of toxins. Experts have a certain truth in saying this. After all, some small workshops in rural areas lack management mechanisms, their sanitary conditions are not up to standard, and their production techniques are relatively backward, which may produce carcinogens such as aflatoxin.

There are actually many methods for making self-pressed oil. The most commonly used method is the special pressing method, which means squeezing the raw materials to produce oil. This method is safer.

There is another way, which is to extract oil. Some chemicals will be used in the refining process. Improper use will lead to chemical residues, which will be very risky for people to eat. Some oil mill owners also use this method to squeeze oil to save trouble.

In addition, the raw materials used by farmers to extract oil cannot be controlled. If the storage environment is not suitable or the storage time is too long, the raw materials can be easily contaminated by aflatoxin, which is difficult to detect with the naked eye. , there is no relevant testing equipment when extracting oil.

To sum up, although the quality of self-pressed oil in rural areas is not as good as barreled cooking oil, it also has its advantages. The concentration is relatively high and it is not mixed with other substances. The raw materials are grown by farmers themselves, and they are squeezed immediately after harvesting. They will not be stored for a long time, and there will be no problem of raw material contamination.

In terms of nutrition and taste, self-pressed oil is better. The barreled oil sold on the market has a more complicated production process and a higher concentration. It looks better, but it has lost its original flavor. The taste doesn't taste like self-pressed oil. In rural areas, self-pressed oil has been eaten for thousands of years and continues to this day, proving that there is no problem in eating it.
