Which is better, earth pressed vegetable oil or refined vegetable oil?

The earth-pressed vegetable oil and the refined vegetable oil I bought, I personally prefer the earth-pressed vegetable oil.

My uncle used to open a small oil mill, the villagers will beat their own rapeseed, soybeans or something to extract oil, before the oil extraction, generally will first weigh the rapeseed, soybeans first, and then according to how many catties of rapeseed or soybeans to calculate the wages, not how much oil you can squeeze in the end to calculate the wages.

Therefore, the villagers will clean up the impurities of rapeseed soybeans before squeezing oil, and some will even wash and dry rapeseed soybeans before squeezing oil, so as to ensure the oil yield.

When it comes to squeezing oil, first put it in a large pot to fry, until it is about to burn and then put it on the oil press to press, first put rapeseed or soybeans into the feed port of the oil press, and then pull the long handle, the villagers use the oil pot and other oil at the oil outlet next to it, and the rest is all considered oil residue, although the oil residue can still be pressed out, but generally pressed twice will not be pressed again, the oil residue will be pulled back to make fertilizer or feed, which is still very nutritious.

Therefore, the soil-pressed vegetable oil is very advantageous in terms of raw materials and purity, and because it is freshly squeezed and eaten, it is generally not squeezed a lot, and it is very fresh.

But if you go to the supermarket to buy refined oil, although it is very expensive and claims to be nutritious, your raw materials will obviously not be home-grown.

Also, in order to reduce costs, in the process of oil extraction, the oil of the raw materials is squeezed as much as possible, and the oil residue should be as little as possible, and then purified, while removing the oil residue, it also removes a lot of minerals, which is not as nutritious as the oil pressed by the soil.

In addition, some chemicals will be added to the refined oil to make it last longer, so when we eat it, it will not be so fragrant.

The only benefit of refined oil is convenience, you can eat it as soon as you buy it in the supermarket, and it will not be as annoying as home-pressed vegetable oil. And not everyone has this condition for soil-pressed vegetable oil. There have to be raw materials, and there has to be time.

It is not easy to distinguish between the soil-pressed vegetable oil and the refined vegetable oil, if it is under the same conditions, the refined vegetable oil will be better, and the specific analysis is as follows:

Clause. 1. Compared with refined vegetable oil, the hygienic conditions of soil-pressed vegetable oil are poorer. I don't know if you've ever seen the oil press work, when I was a child, I generally took my own rapeseed or cotton seed to squeeze oil when I came to the countryside for the Chinese New Year, at that time there was not so much blended oil now, and I couldn't afford to eat blended oil, generally the family squeezed oil by themselves and then found a master who knew how to "lift oil" to help refine some, which needed to add certain chemical raw materials; The refined vegetable oil is generally produced by large machines, and the process and standards must meet the national health conditions standards.

Therefore, the production process of this oil is not standardized and unhygienic, so from the perspective of this production process, it must be that the vegetable oil is poorly pressed.

Clause. Second, in terms of raw materials, the earth-pressed vegetable oil may be better. Because the rapeseed used in the self-pressed rapeseed oil must be relatively good, and the quality is ***; And refined vegetable oil is not what I see, and it is not certain whether there will be a situation of good refill.

Because no matter how big the enterprise is, it is very difficult to check the use of raw materials, because it is not operated by one person, it is inevitable that there will be some flaws, because the refined vegetable oil may not be as good as the soil-pressed vegetable oil in terms of materials.

Clause. Third, from the perspective of the edible process, because vegetable oil is not sesame oil, it will not be eaten directly, even if the sanitary conditions are poor, but the oil will burn to more than 130 degrees in the process of stir-frying, so there will be no problem with the sterilization and disinfectant, and I am afraid of the use of chemical raw materials in the process of refining by myself.

To sum up the above, if the raw materials are under the same conditions, refined vegetable oil is still more reliable.

There is no difference between pressed canola oil and pure canola oil. Pressed rapeseed oil is just the production process for pressing, and the pressed oil is pure rapeseed oil.

Pressed rapeseed oil is classified due to different production processes, and other rapeseed oils are classified as leached rapeseed oil due to different production processes of acorns.

Rapeseed oil is classified according to raw materials: it can be divided into genetically modified rapeseed oil and non-genetically modified rapeseed oil for the first burn.

Rapeseed oil is divided into erucic acid content composed of fatty acids: it can be divided into general rapeseed oil and canola oil.

The crushing process of rapeseed oil has a great impact on the quality and taste of the oil. A good process can better preserve the nutritional value and flavor of the oil. In response to this problem, I will introduce several common rapeseed oil pressing processes, and which pressing process is better.

First of all, mechanical pressing is a traditional rapeseed oil pressing process, which usually includes two methods: pancake pressing and flat-bottom mill pressing. The mechanical pressing process is simple and inexpensive, but it leads to a decrease in the quality of the oil because of the high altitude heat and mechanical pressure generated during the mechanical pressing process, which destroys the beneficial components and natural aroma of the oil. In addition, the efficiency of mechanical pressing is low, and the oil yield is usually around 70.

Secondly, the chemical method is another commonly used rapeseed oil pressing process, which is able to extract large amounts of oil in a short period of time. However, this method requires the use of chemical solvents to treat large quantities of seed kernels, such as trichloroacetic acid, which leads to a decrease in oil quality and the risk of residual chemicals, making it unsuitable for the production of high-end oils.

The best method of modern rapeseed oil pressing process is cold pressing. This process uses natural pressure and low temperatures to ensure that the nutrients and flavors in the oil are preserved to the maximum. Compared with mechanical pressing and chemical methods, cold pressing does not destroy the beneficial components of the oil, retains a large amount of unsaturated fatty acids and other nutrients, and the oil is of good quality and mellow taste.

In addition, the cold pressing process does not require the use of any chemical solvents, which is naturally environmentally friendly and has no risk of residual chemicals.

In conclusion, while mechanical pressing is a traditional method and chemical methods have the advantages of high output and low cost, the cold pressing process is the best option. Because the cold pressing process retains the natural flavor and nutrients in rapeseed oil, and does not produce any harmful chemicals, it is a healthier and more environmentally friendly oil product. <>

No! The erucic acid content of rapeseed oil is as high as 40%, and the national food safety standard stipulates that it should not be higher than 3%, so it is recommended to buy rapeseed oil that meets the national production standards, such as Arowana grandmother Township small pressed rapeseed oil, carp rapeseed oil, etc.

Rapeseed oil is edible, and this oil is very tasty.

Hello, if you see the oil drum in the supermarket marked with pressed rapeseed oil, it means that this barrel of oil is rapeseed oil produced by the traditional ancient pressing process.

Pure rapeseed oil, just means that this barrel of oil is rapeseed oil, and no other oils are added. But the pressing process is not specified, it may be physical pressing, it may be chemical leaching.

Pressing is the process of extracting rapeseed oil, thank you.

Generally, it will not be mixed with messy additives, maybe there are a little more impurities or something, and I have been eating peanut oil brought by my hometown, which feels more fragrant.
