Fearing dirty cooking oil on the market, Nghe An people rush to press oil for use.

Recently, concerns about the problemfake cooking oilWith dirty cooking oil on the market, people in many places have chosen to bring their own peanuts and soybeans to press for use. Even families that do not do farming also buy peanuts from the people to press.

Ms. Le Thi Tuyet, an oil press owner in townNam Dansaid: In recent years, the number of people coming to press oil as well as buying pressed peanut oil for use has increased significantly. Previously, Ms. Tuyet's family used hydraulic presses to press manually, now they press by machine so the productivity is higher, each day they can press 4-5 tons of peanuts.

With the press, there will be 4 stages to complete the oil pressing process, first is peeling the peanuts (some places people can press the shells but on the condition that the peanut shells must be cleaned thoroughly), then drying, then putting them into the press, and finally putting them into the air compressor to produce the finished oil.

According to Ms. Tuyet, 1 bird's nest of peanuts will produce a 5-liter can of oil, while for soybeans and sesame, 1 bird's nest will only produce about 1 liter of oil. Because peanuts are readily available, people come to press peanuts and soybeans for their own use, and some people even press them in advance to send to their children in Hanoi and Saigon for use.

Currently, the movement of using self-pressed cooking oil is spreading throughout the localities. In the districts of Hung Nguyen, Nghi Loc, Thanh Chuong, Dien Chau, almost every locality has facilities for pressing oil manually or by machine to serve the needs of the people. With the press, each facility usually has to invest about more than 100 million VND for machines for grinding, drying, pressing and filtering oil.

For manual oil pressing, the peanuts after being peeled are ground, then steamed (steamed), and finally packed into small packages and put into a press to use hydraulic pressure to press out the oil. The press is a round cylinder, about 80-90cm high, when the peanuts are steamed and heated, the oil will be pressed out. Manual pressing takes more time, and all stages require human intervention.

In addition, currently on social networks, many online businesses also sell mini oil presses for home use. However, mini presses often have low capacity and take a long time to press, so very few people use them.

Mr. Thong, the owner of an oil pressing facility in Dien Thinh area (Dien Chau) said that the trend of self-pressing oil is very popular among people. At Mr. Thong's facility, people come to press oil every day, many people press 100kg, some people even press several hundred kilograms for later use. Many families in Vinh city when returning to their hometown also buy peanuts from the people to press.

Although the prices of peanuts, sesame, and soybeans on the market are quite high, 1 bird's nest of shelled peanuts costs 350,000 VND, peanuts are 500,000 VND, and a 5-liter can of peanut oil costs 400,000-500,000 VND, while the price of a 5-liter can of industrial oil on the market is only 150,000-200,000 VND. If compared, it is clear that self-pressed oil is 2 to 3 times more expensive, but people still use it.

Ms. Nguyen Thi Nga, Nam Dan town shared that now there are all kinds of food on the market but the quality is unknown, while peanuts can be bought from the people when they are in season and stored, when they are all eaten they are pressed, each liter of oil costs only 30,000 VND for labor, although it is more expensive than oil in the market but the quality is more guaranteed. Ms. Nga also questioned that the price of peanuts and soybeans on the market is so high, while a 5 liter can of oil costs only 150,000 VND, which is hard to believe.

Although the price is higher than bottled oils sold on the market, many families still choose to use self-pressed oil to ensure their health. Photo: TD

Ms. Phan Thi Huong in Ben Thuy Ward (Vinh City) said: In recent years, she has stopped buying vegetable oil from the market and has switched to using home-pressed peanut oil. Every time she returns to her hometown, Ms. Huong asks her siblings to buy peanuts in advance to store. In addition to using the pressed oil at home, Ms. Huong also sends it to her children studying in Hanoi, because according to her, she knows that the product will be more secure than oil bought at the market. Especially in Hanoi, recently, there has been a lot of talk about dirty oil and dirty animal fat, so she just presses it in advance and sends it to her children to use.

Many people say that they are used to using home-pressed oil, and now if they switch to oils bought at the market, it is difficult to eat. Peanut oil is golden and thicker, so it is also less expensive./.
