What is the difference between physically pressed oil and pressed primary oil

There is no difference, because the process of pressing the first grade oil is the "physical pressing method", so the pressing of the first grade oil can also be called physical press oil.

Now Chinese edible oil.

The production method is divided into pressing (physical) and leaching (chemical) two, the production process of physical pressing method requires that the raw materials should be selected, and the oil is crushed, steamed and fried and extruded after removing impurities and stones, so that the oil is separated from the oil, and the fried seeds are added in the machine pressing process, and after being pressed by the press, it is made by high-tech natural filtration and purification technology.

Physically pressed oil:

Pressed peanut oil has a complete color, aroma and taste, and retains the characteristics of various nutrients.

The earliest method of oil extraction used was pressing, which began to use hydraulic pressing about two centuries ago. Due to the labor-intensive nature of hydraulic presses and the slow speed at which large quantities of oil are processed, methods of continuous or physical extraction have recently been developed, including the French screw press and the Anderson screw press.

These devices are effective for oilseeds with a high oil content (30% to 50%) such as corn germ and sunflowerseeds, but not very effective for oilseeds with low oil content (21%) such as soybeans. Presses or screw presses can be used prior to solvent leaching and in combination with solvent leaching technology.

The physical pressed oil has complete color, aroma and taste, and retains the characteristics of various nutrients, but the first quality of pressed peanut oil is relatively high.

The production process of physical pressing method requires that raw materials should be selected, and the oil is crushed, steamed and fried and squeezed after removing impurities and stones, so that the oil is separated from the oil, and the fried seeds are added during the machine pressing process, and after being pressed by the press, it is made by high-tech natural filtration and purification technology.

It maintains the original flavor of peanuts, mellow flavor, rich in vitamin E, long shelf life, and no additives, no solvent residue and soap content, is a pure natural green food produced by the combination of modern technology and traditional technology.

According to the latest standard edible oil, it is divided into 4 grades, and the fourth grade is the lowest grade; Second, we should look at the place of origin, which mainly refers to the place where the raw materials of the product are produced; Third, it depends on the raw materials, that is, whether they are genetically modified raw materials; Fourth, it depends on the production process, that is, the edible oil is produced by "pressing method" or "leaching method", and the pressed oil can maintain the original nutrients of the raw materials and the quality of the oil is relatively pure.

There are two kinds of edible oil in the supermarket: pressed and physically pressed, which is better?

Hello, there are two kinds of pressing and physical pressing on the supermarket edible oil, and physical pressing is more recommended! 1. In fact, there is no difference between physical pressing and pressing, the two are the relationship between inclusion and being included, and pressing includes two types, one is physical pressing, and the other is chemical leaching. 2. Physical pressing is a kind of pressing, which refers to the separation of oil from oil through physical pressure, without adding chemical additives, ensuring the safety and hygiene of food, no pollution, and natural nutrition will not be destroyed.

Chemical leaching is to press out the oil through chemical substances, and the oil yield is higher than that of physical pressing, but there are potential safety hazards.

Physical pressing oil is to separate the oil directly from the oil by physical pressure, and the whole process does not involve any chemical additives, so as to ensure that the product is safe, hygienic, pollution-free, and the natural nutrition is not destroyed.

Production process: The processing technology of pressing oil is the "physical pressing method", and the production process of the physical pressing method requires that the raw materials should be selected, and the oil should be crushed after impurities and stones, steamed and fried, and extruded. The oil is separated from the oil, fried seeds are added during the machine pressing process, and after being pressed by the press, it is made by using high-tech natural filtration and purification technology.

Nutritional advantages: It maintains the original taste of peanuts, has a mellow flavor and is rich in vitamin E

Long shelf life, without any additives, no solvent residue and soap content, is a combination of modern technology and traditional technology to produce pure natural green food.

Pressed peanut oil.

It has complete color, aroma and taste, and retains the characteristics of various nutrients.

"Machine pressed peanut oil" because of the use of pure physical pressing method, retaining the peanut and the original flavor, so the requirements for peanut raw materials are very strict, the raw materials are required to be fresh, acid value, peroxide value.

low, and therefore relatively high; At the same time, because only the pressing is carried out, the residual oil in the peanut cake is high, and the oil yield of the pressed oil is relatively low. Therefore, the ** of pressed peanut oil is relatively high. Sell Zhilu.

Physical pressing means that the plant is separated from the oil by pressure, without the addition of any additives. Very healthy cooking 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.

Pure pressed oil is generally processed at less than 60 degrees Celsius. 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 oilseeds, cleaning, shell kernel separation, seed kernels, low temperature and mountain silver drying, quenching and tempering, cold pressing, fine filtration of refined oil. Aromatic oil extraction process:

Oilseeds, cleaning, shell separation, seed kernels, drying and cooling, crushing and peeling, billet rolling, high-temperature steaming and frying, high-temperature pressing, precipitation filtration, refining refined oil.

Pressed peanut oil.

Peanuts are crushed by raw materials, selected (to separate peanuts from shells), stir-fried to 6-8 into a feast mature, and then physically pressed by an 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 more than 80% unsaturated fatty acids (including oleic acid and linoleic acid. It also contains saturated fatty acids such as palmitic acid, stearic acid and 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 data, the use of peanut oil can decompose cholesterol into bile acids in the human body and excrete them from the body, thereby reducing the content of cholesterol in the blood plasma.

"Physically pressed oil" refers to a "healthy oil" refined by the physical pressing process. The pressing process retains the nutrients in the oil and does not add chemical solvents to ensure the safety, purity, nutrition and deliciousness of the oil, which meets the needs of the human body and is suitable for long-term consumption. This process is mainly used for peanut oil in China.

Olive oil, nut oil, and other high-grade oils.

At present, the advanced pressing process is "Luhua."

5S Pure Physical Pressing Process". The process strictly controls the selection, roasting, pressing, filtration, storage and other links through advanced technology, and does not add chemicals in the whole process, retaining the natural nutrition and original aroma of the oilseed rental eggplant. The process has reached the international advanced level and has been fully recognized by domestic oil experts.

Summary. Hello, the two are better than the oil pressing, because the processing technology of the oil pressing is the "physical pressing method", which is to extract the oil from the raw materials by mechanical extrusion through physical methods, the advantage of this method is natural and pollution-free, but the disadvantage is that the oil yield is low, and the residual oil of the general raw materials reaches 7 8. This production process requires the raw materials to be selected and made using high-tech natural filtration and purification technology.

It maintains the original flavor of soybeans, mellow flavor, rich in vitamin E, long shelf life, and no additives, no solvent residue and soap content, is a pure natural green food produced by the combination of modern technology and traditional technology.

Hello, compared with the two or oil pressing, because the processing technology of lead pressing oil is "physical pressing", which is through physical methods, using the way of machine response extrusion to extract oil from raw materials, the advantage of this method is natural and pollution-free, but the disadvantage is that the oil yield is low, and the residual oil of general raw materials reaches 7 8. This production process requires the raw materials to be selected and made using high-tech natural filtration and purification technology. It maintains the original flavor of soybeans, mellow fragrance, rich in vitamin E, long shelf life, and no additives, no solvent residue and soap content, is a pure natural green food produced by the combination of modern technology and traditional technology.

Pressed soybean oil retains the original flavor of soybeans, and the disturbance is very strict and early knowledge of soybean raw material requirements, raw materials require freshness, low acid value and peroxide value, so it is relatively high; At the same time, because only the soybean cake is pressed, the residual oil in the soybean cake is high, and the oil yield of the pressed oil is relatively low. Therefore, the ** of pressed soybean oil is relatively high.

Hope it helps

Do you have any other questions? If you're still satisfied with me, I'm looking forward to a small hole ruler evaluation, thank you!!

From the point of view of eating, of course, it is better to physically press. The question should be the difference between physical pressing and leaching. Physical pressing, or crushing, refers to the separation of oil from raw materials under the action of purely physical external forces.

The leaching method is that after the initial pressing, He Xing still has the remaining oil, which is mixed with chemical additives and then pressed twice.

The mixed oil with ** and chemical additives is squeezed out after condensation treatment to separate ** and additives, which promotes a higher oil yield. But there are more or less concerns about additive residues. As a result, the oil yield of the physical press is low, but there are no additives.

The advantages of physically pressed oilIt has complete color, aroma and taste, and retains the characteristics of various nutrients, but the ** of pressed peanut oil is relatively high.

Summary. Physical pressing oil is good.

Physical pressing oil is good.

The physical pressing method is to crush, steam, fry and squeeze the raw materials, and sell the oil to separate the oil directly from the oil. The pressing oil using physical methods can maintain the original nutrition of the raw materials, and the quality of the oil is relatively pure. However, the oil yield is low, the utilization of raw materials is low, and the processing cost is high.

It is understood that the oil pressing process is currently mainly used in China for peanut oil, olive oil, Jiangao Youyou fruit oil, sesame oil and other high-grade oil products.

The difference between the two: 1. The processing technology is different: the pure pressed oil is processed by the "physical pressing method", the physical pressing method relies on physical pressure to squeeze out the oil, and the leaching oil is processed by the "chemical leaching method", using the principle of chemical extraction, using solvent oil to extract oil raw materials, and then made by the "six detonation" process.

2. Different nutrients: the processing technology of pure pressed oil will not destroy unsaturated fatty acids such as linoleic acid, and can retain the original nutrients of oil crops, while the processing technology of leaching oil will destroy unsaturated fatty acids such as linoleic acid, resulting in the loss of nutrients. 3. Different raw material requirements

Pure pressed oil has strict requirements for raw materials, low oil yield, and high oil yield, and low requirements for raw materials and high oil yield for leaching oil, so it is also low.
