Edible oil is essential in our diet and life, like salt and rice. Salt is “the head of all flavors”, and rice is one of our staple food. Some people say that the calories of edible oil are generally high, so why should we eat edible oil? Because edible oils can not only provide calories for our bodies, the most important thing is that it can provide the human body with nutrients such as linoleic acid, linolenic acid, vitamin A, vitamin D, vitamin E, and vitamin K. The above nutritional ingredients are unable to synthesize the human body itself, and it is necessary for the human body, so edible oil cannot be lacking in our diet.

Types of edible oil in life

Although there are many types of edible oils in diet, if they are divided according to the category of raw materials, they can be divided into two simple categories, namely: animal oil and vegetable oil. There are many people who eat animal oil decades ago, mainly lards; and now people mainly eat various vegetable oils, such as rapeseed oil, peanut oil, soybean oil, olive oil … and so on. Today we are mainly talking about vegetable oil.

Today, there are many types of vegetable oils on the market. Various brands are enough to be dazzling. As long as people who have purchased edible oil on the supermarket, I believe it will be deeply touched. However, as far as the extraction and processing process of vegetable oil is concerned, it is generally divided into two types: “pressing” and “immersion”, and the selling price of pressing oil is generally higher than the leaching oil. Due to the new standards of consumption oil in my country, there are clear stipulation: requires the extraction method of edible oil in the label of edible oil, that is, the word “pressing oil” or “leaching oil”. Therefore, when we buy food, we can selectively buy according to our own needs.

However, many people do not know what the difference between the two is in the face of “pressing oil” and “dipping oil”. In other words, is it better to squeeze oil or soaked oil for edible vegetable oil? Let’s talk about this problem in detail.

What is the difference between pressing oil and leaching oil?

From the above introduction, we can know that the edible vegetable oil we eat is divided into two categories: presumption of oil and leaching oil from the extraction process. So what is the difference between them? Or is it good or bad? Take a look.

NO1: Different manufacturing process

Squeeze

The squeezing process of edible oil has a history of more than 5,000 years. It is a physical presumption method. With the help of mechanical physical pressure, it is extracted and separated from the oil from the oil. The entire process does not add any chemical additives.

Immersion method

The immersion process of edible oil, this oil -making process originated in France. It first crushes the raw materials and places it in an easy -to -volatile organic solvent for dissolution, and then the mixture of organic solvents and oils in the appropriate vacuum Deficiency is performed at a degree and temperature to achieve the separation of oil and fat. Finally, the “five -off” process refined the edible oil that meets national standards. For example, soybean oil on the market is almost made by leaching process.

Press oil

Therefore, from the perspective of the manufacturing process, the squeezing process is a pure physical production process without adding any chemical additives; and the use of organic solvents with the use of organic solvents is obviously a processing process using chemical additives to extract oil.

NO2: The raw materials of oil are different

The reason why vegetable oils are squeezed and immersed, which are related to the characteristics of the raw materials for making edible oils, and mainly determine the taste of the raw materials, the oil content level, and the use of the final edible oil.

For example, for the high oil content of the raw material itself, or the produced oil products mainly highlight the special flavor of the raw materials itself, then you should choose a physical presumption method. For example, high -end oils such as peanut oil, sesame sesame oil, olive oil, and nut oil on the market. At the same time, the quality of edible oils made by physical crushing is better, safe, pollution -free, and non -added. The disadvantage is that the oil output rate is relatively low.

For raw materials with low oil content, it is generally used to extract oil. Because the use of immersion can increase the oil output rate, compared to the general oil rate of the squeezing method can increase by about 3%. The typical oil of the leaching method is soybeans.

Soybean oil

Therefore, because there are many types of raw materials that can make edible oils, the physical and chemical characteristics of each oil are different. Then whether to use crushing or immersion method, first of all, you must consider the characteristics of the variety of oil, not what you want.

NO3: Different nutritional ingredients

The entire processing process of the pressing process is a physical nature, and the final oil is filtered by natural plant fibers. Because of this, the edible oils made fully retain the rich nutrients in the oil. The entire process has no chemical component pollution, has the characteristics of safety, nutrition and taste, and is a pure natural green oil -making process.

Compared with the pressing process, due to the addition of chemicals, in order to achieve the national edible oil quality and hygiene standards, the immersion oil must be dewashed, dehydrated, and acid -delyoly. However, everything has its two sides, and it is good for advantages. Therefore, the immersion oil will inevitably cause some nutrients such as vitamins and other nutrients during the refining process.

It can be seen that from the perspective of nutrition, the richness of the nutrients of pressing oil is higher than that of leaching oil.

Buy edible oil, choose pressure squeezing oil or soaked oil?

From the above analysis, it can be seen that the oil and soaking oil have their own advantages and disadvantages. Pressing oil is the perfect combination of traditional and modern crafts. It has the advantages of originality, no additives, rich nutrition, long shelf life, and green naturally, but the price is generally high and the oil output rate is relatively low. Although immersion oil is a chemical extraction method, and

Most of the nutrients are destroyed,

But it also has its advantages, has the characteristics of relatively cheap prices, high fuel rates, colorless and tasteless.

Therefore, whether it is pressing oil or soaking oil, it is a consumption oil that meets the national food safety regulations, and can be eaten with confidence. As for which one to choose, you must choose according to your own food taste. However, in general, eating consumption oil must follow the laws of buying small bottles, multi -varieties, less oil, and good oil, which is more beneficial to health!
