Is all peanut oil physically pressed? Does it mean that the squeezing is the healthiest?

The production methods of different brands are different, and there are more physical presses, such as Longda fresh peanut oil, which is pressed with seasonal peanuts. There is also the leaching method, which is relatively speaking, the peanut oil leached by chemical principles has much less nutrients than the physically pressed peanut oil.

I don't think it's necessarily healthy to be squeezed.

Home-pressed peanut oil lacks semi-refining and full refining processes, and aflatoxin B1 is easily enriched in peanut oil, because aflatoxin B1 is easily enriched in earth-pressed peanut oil.

It is advisable for consumers to buy pre-packaged finished peanut oil from supermarket chains, as these oils are refined and filtered to remove aflatoxin B1 and related impurities, so they are safer to eat.

There are some components in vegetable oil that are beneficial to health, such as vitamin E and phytosterols, which are also removed in refining, and from a nutritional point of view, earth-pressed oil has certain advantages over refined oil. However, there are many impurities in the clay pressed oil, and it is easy to produce more harmful substances during the cooking process.

In addition, the nutrients lost in refining can be obtained from other foods. The harm caused by the smoke of soil oil and the harm caused by benzopyrene cannot be eliminated. Although their harm may not be immediate, small risks are not necessary to be taken as long as they can be avoided.

Especially for stir-frying or frying, refined oil should be a better choice.

The above content refers to People's Daily Online - earth-pressed peanut oil may not be good.

The process of peanuts being pressed into peanut oil is mainly composed of the following parts, first of all, people will peel the peanuts into grains. People will put the peeled peanuts on top of the dustpan, through continuous **, continuous screening of the broken shells and firewood and grass. People need to further use the round robe sieve to remove the soil chips, stones and other debris, peanuts impurities can not be too much, generally not more than the total amount of peanuts.

After the peanut kernels are screened, the peanut kernels need to be crushed by tools, and in the process of rolling, the peanut kernels cannot be spread too thick. <>

In the process of grinding, people should grind the peanut kernels evenly, and at the same time, the thickness of the embryo needs to be controlled in millimeters. People can use the iron pot cage drawer to boil water, and after the water boils, you can put the milled green billet in the iron pot cage drawer, and it should be evenly spread. People need to control the temperature in this process, the temperature needs to be kept above 100, and the steam needs to be evenly adjusted.

After steaming, people need to touch it with their hands to control the moisture in it, and when people find that they can feel the oil with their hands, it means that this step has been done. <>

After the raw embryo is steamed, it is the cooked embryo, and people need to quickly stack the cooked embryo cake, and the cake needs to be wrapped in a single circle. The grass that people spread when packing should be kept even, and the cooked billet needs to be compacted and flattened after it is loaded, and the middle needs to be slightly higher than both sides. When people carry out this step, they need to ensure the pressing time and the temperature of the cake.

After that, people need to press it first, and they need to put the artificial auger in a place with a suitable temperature, and after the cake is loaded, it needs to be pressed immediately, and it must be pressed step by step. <>

When it is found that the oil yield rate reaches 90%, people can carry out the extraction and unloading of the cake, and at the same time, the edge of the cake needs to be scraped with a knife. People need to further crush and press the embryo, need to crush the finished cake, need to pass through a three-purpose sieve, and need to sieve out the impurities. After all the processes, the oil needs to be pressed again, the oil after the two presses needs to be combined and filtered, and the filter residue can be pressed repeatedly.

At this time, the peanut oil has been completely squeezed out, and it can already be consumed by people.

The process of pressing peanuts into peanut oil is to take the peanuts to the machine, and the oil will be produced after repeated crushing.

The first thing is to wash the peanut sludge, then peel out the peanut kernels inside, and then put it in a blender to stir, and then add a little vegetable oil and a little flavor to make peanut oil.

The peanuts need to be put in the oil press, and the oil press will work, and there will be pressure to crush the peanuts, so that there will be peanut oil.

The differences are as follows:

1. The purity is different.

Pure pressing means that the purity of the oil is relatively clean, and the impurities of the oil are removed, so there is no other taste. Aroma press refers to an oil that contains an unflavored taste.

2. The characteristics are different.

Pure pressed oil is fed into the oil press for pressing without heating or at low temperature before the oil is pressed. Aroma oil extraction is hot frying, generally before the oil is extracted, the oil is cleaned and crushed and then heated at high temperature, and the peanuts can smell the fragrance when they are heated.

3. The color is different.

The color of the pure pressed oil is clearer and the taste is lighter. Aroma oil extraction is to squeeze the seeds of oil crops after roasting, the smell is particularly fragrant, the color is darker, and the yield is higher.

<>4. The temperature is different.

Virgin pressed oil is generally processed at temperatures below 60. Before the oil is pressed, the oil is heated at high temperature, so that a series of changes occur inside the oil.

5. The process is different.

Pure pressing oil production process: from oil, cleaning, shell kernel separation, seed kernel, low temperature drying, quenching and tempering.

Cold-pressed, finely filtered refined oil. Aroma oil extraction process: oilseeds, cleaning, shell kernel separation, seed kernels, drying and cooling, crushing and peeling, billet rolling, high-temperature steaming and frying, high-temperature pressing, precipitation filtration, refining refined refined oil.

Pressed peanut oil:

Peanuts are crushed by raw materials, selected (so that peanuts are separated from the shell), stir-fried to 6-8 maturity and then physically pressed by the oil press, and the products after pressing are pressed peanut oil and peanut dregs, which are edible. Oil presses are divided into vertical top oil presses and screw oil presses.

Peanut oil is light yellow and transparent, the color is clear, the smell is fragrant, the taste is delicious, and it is a relatively easy to digest edible oil. Peanut oil contains unsaturated fatty acids.

More than 80% (which contains oleic acid, linoleic acid.

It also contains palmitic acid and stearic acid.

and saturated fatty acids such as eicosanic acid.

Judging from the above content, the fatty acid composition of peanut oil is relatively good, which is easy for the human body to digest and absorb. According to foreign information, the use of peanut oil can make cholesterol in the human body.

Breaks down into bile acids.

and excreted from the body, thereby reducing the amount of cholesterol in the blood plasma.

Pressed peanut oil and peanut oil are not the same, so what is the difference between pressed peanut oil and peanut oil?

Peanut oil, which is an edible oil made from peanuts, is one of our most commonly used oils, peanut oil contains fatty acids and glycerides like fatty acids, which are important components of our human body, and the glycerides in peanut oil can increase the aroma of vegetables and improve our appetite. Peanut oil is a relatively easy to digest oil, so we often use peanut oil in our daily life.

The pressed peanut oil, peanuts are crushed by raw materials, selected (so that the peanuts are separated from the shell), stir-fried to 6-8 maturity, and then physically pressed by the oil press, and the products after pressing are pressed peanut oil and peanut dregs, which are edible. Pressed peanut oil contains more than 80% unsaturated fatty acids (including oleic acid and linoleic acid. In addition, pressed peanut oil also contains saturated fatty acids such as palmitic acid, stearic acid and eicosanic acid.

Blended oil refers to the proportional blending of multiple oils, while peanut oil is directly pressed from peanuts. Then, the blended oil is better or the peanut oil is better, the blended oil will be more balanced in all aspects of the substance, and the nutritional value of the peanut oil is relatively high because of the single, and many people will say that the peanut oil is fragrant, which is also not the blended oil.

However, because blended oil balances various oils, it may also be safer for some more sensitive people. In short, there is no absolute standard for blending oil or peanut oil. And no one stipulates that everyone can only use one of these ones, and it is not good to eat the same oil for a long time, so everyone can eat it instead.

And peanut oil because the raw material is made of peanuts, so it is usually more expensive than blended oil, but it is generally not too expensive, so it is still within the acceptable range. Therefore, when you buy, you don't have to worry too much about whether blended oil or peanut oil is better, this time you buy blended oil, then next time you try peanut oil, which can be said to be the best of both worlds.
