Is manual oil extraction really healthy? How long is the shelf life of self-extracting oil?

For rural people, they are used to the taste of self-squeezed oil, and they also think that self-squeezed oil is more delicious. Compared with all kinds of rapeseed oil sold in the market, I think it's better to squeeze the oil yourself to make it fragrant. In fact, every villager treats the rapeseed oil he eats very carefully and seriously. In order to ensure good oil extraction, rapeseed needs to be dried, screened and screened several times before being dragged to the oil press room, so it is not scientific for experts to say that it is inedible. Is manual oil extraction really healthy?

depending on the situation, if you have rich experience in oil extraction, it is definitely no problem. If you go to a small workshop to buy so-called "self-extracting oil", you have to pay attention.

Self-extracting oil in rural areas is safe to eat, with a history of thousands of years. With any additives and other chemicals, there are still many processes of self-extracting oil, and this fragrance mainly comes from the frying process. At that temperature, the degree of peanut shell is very important.

Experts mainly use certificates as the basis for judging safety and reliability. In this way, it is human nature that self-squeezed oil with three products is regarded as inedible by experts. It's just that experts ignore the simplicity of farmers' hearts. All the people who go to squeeze the oil mill are neighboring neighbors, and rapeseed oil is also planted by themselves. Only a processing fee can squeeze the oil, so this self-squeezed oil is really a good oil without any blending.

If the oil is not squeezed by yourself, but purchased through the Internet or other channels, it may be exploited by a willing heart to blindly hear that the farmers are squeezing oil themselves. After all, the self-squeezed oil with three products is likely to be fake when the goods are in circulation. At this time, experts should refer to it.

In fact, the cost of self-pressed rapeseed oil is not low. Our kilo of rapeseed is already 2-3 yuan, and the oil yield of 1 kilos of rapeseed oil is only over 3%. Therefore, the minimum price of this kilo of self-pressed rapeseed oil is around 8 yuan, which is not much cheaper than the bottled oil in those supermarkets, but the word of mouth is better than commercial oil in the hearts of rural people. Why experts say you can't eat self-squeezed oil

1. Self-squeezed oil is unsafe. There are two main links. First, when frying, you can't fry it. Second, you can't use plastic for the oil. In the south, we squeeze rapeseed oil, which is called raw oil. When we get home, we have to boil it in a pot for a while, so that the water inside is more fragrant and stored for a longer time. After cooling, we pour it into the oil tank.

2. There are a lot of cerebral infarction in the rural elderly, which began in their fifties. The reason may be self-extracting oil or water problems. Only these two can cause this disease generally. This self-squeezed oil is very thick, unlike the blended oil that has been extracted. Some people will say that generations have been eating like this. Why didn't you find the problem before? Let me talk about my personal opinion. First, there is less physical labor now, and people from rural areas will know what they used to do! Now they are all replaced by machinery. Second, I ate more oil. In the past, my family ate a tank of oil for several months, and even had a joke that it had become more after eating for half a year. Later, I found that I drowned a mouse.

3. In fact, experts are not necessarily unreasonable. Self-extracting oil is known to be good, but it is unstable. The oils of the Zhang family and the Li family are different. Some thrifty old people are mixed with all kinds of mildew, and peanut oil is most afraid of mildew. Big brands are unlikely to be faked, but unfamiliar villagers buy them, but they are more likely to be faked. Third, for example, pesticide residues, the vast majority of old farmers over 5 and 6 only know about pesticides efficiently, even if they use pesticides for their vegetables, and because their vegetables have increased pesticides. How long is the shelf life of self-squeezed oil

Generally, the shelf life of brand oil bought outside the supermarket is about one or two years, while the edible oil made by hand can be kept for more than two years. Of course, it also depends on how you squeeze it. When you precipitate and filter it and store it in a cool and shaded place, it is no problem to keep it for two years.
