Why is it so difficult for migrant workers to eat less oil?
Just order a takeaway, the oil is so much like you don’t need money.
Boss, I really thank you…

I finally have time to stew soup on the weekend, but the thick layer of grease on the surface, after 20 laps with a spoon, the rippling piece of clear water will always be submerged in an instant. .

The weather is getting hotter and hotter, is there no way to be less greasy?
Where there are difficulties, there are solutions. We found that some businesses have launched “food oil-absorbing paper” – throw a piece into it before eating, and you can absorb the oil. Eighty-eight.

This thing is both heartwarming and moaning: looks a bit like an IQ tax? Is it really safe?
To find out, we placed an online order for a hot-selling food absorbent paper, and also consulted experts in food materials to see if it was reliable.
Do an experiment first
As soon as the food blotting paper arrived, we tried all kinds of food.

Wow, the results are immediate!
Is this sucking water or oil? Let’s compare it with ordinary paper towels.
Prepare two cups of the same water-oil mixture to simulate the usual situation of oil floating on the soup.
Use food absorbent paper on the left and ordinary paper on the right. The paper sizes are similar.
Then put both the absorbent paper and the tissue paper into the cup, press it into the soup, and fully absorb it. Wait until both sides of the paper are soaked and fully absorbed before taking it out.
If you look closely, it will be very obvious-In the cup of oil-absorbing paper, there is still a thick layer of grease; in the cup of oil-absorbing paper, it is no longer visible. Obvious oil layer.
Look at the removed paper again – the oil-absorbing paper on the left is full of yellow grease, while the paper towel on the right is only stained with light yellow, and a lot of inhalation is water.
In this way, the oil-absorbing paper is well-deserved, and its adsorption effect on oil is very significant.
How much oil can that absorbent paper absorb? We tested it again with a bowl filled with only oil.
With bowl and oil, it weighs 80 grams. After putting in a piece of absorbent paper, it becomes a total of 81 grams.
Poke it twice, wait for the paper to be soaked in oil, take it out, and weigh it again. Only 45 grams are left with the bowl and oil. That is, 35 grams of grease is absorbed by a single absorbent paper.
According to the “Reference Intakes of Dietary Nutrients for Chinese Residents”, 1 gram of fat has 9 kcal, and 35 grams of fat is 315 kcal.
It’s all paper
Why does oil-absorbing paper work well?
Although it looks similar to ordinary paper towels, oil-absorbing paper is essentially a relatively loose non-woven fabric.
The characteristic of non-woven fabrics is that they are very loose and porous, like a flat sponge. Sponges are familiar to everyone, and can absorb a lot of oil or water.
Non-woven is not a kind of fabric, but a weaving method like knitting and woven. Like our common masks, face towels, etc., most of them are made of non-woven fabrics.

Although they are all non-woven fabrics, the raw materials of this type of oil-absorbing paper are divided into two categories – plastic and paper.
The raw materials marked as polyethylene (PE) and polypropylene (PP) are plastics; the raw materials marked as virgin wood pulp and raw bamboo pulp are paper.

Their characteristics are obvious:Paper-type oil-absorbing paper absorbs both oil and water, and absorbs oil and also takes away a lot of soup; while plastic-type oil-absorbing paper, The main thing is to absorb oil, and only take away a small amount of soup.
This is because paper is not very lipophilic, and the principle of oil absorption mainly depends on the structure of non-woven fabrics, and some oil absorption additives are added. However, plastics such as PE and PP are an organic substance, which is lipophilic but not hydrophilic, and grease is also an organic substance, and there is an additional layer of suction that is similar to compatibility.
Blotting paper into hot soup
Is the food still safe?
As soon as they hear “plastic”, many people will subconsciously think that it is impossible – what should I do if I put it in soup or touch hot food, and the harmful substances are precipitated?
In fact, it is a regular product, so don’t worry about safety.
First, the materials in these products can withstand temperatures in excess of 100 degrees. For example, the aforementioned oil-absorbing paper raw materials, polyethylene (PE) and polypropylene (PP), will not deform or decompose even if they are boiled in boiling water.

In addition, there are strict regulations on the harmful substances that may be precipitated from these products at high temperatures.
Whether it is plastic or paper, the requirements for the total migration of harmful substances in oil-absorbing paper are the same: if placed in a condition of 100 degrees for 1 hour, the total migration should be less than or equal to 10mg/ kg.
The plastic water cups, plastic wrap, plastic crisper boxes, etc. that we often use to hold hot water are all of the same standard. Within this limit, it is very safe for the human body.
Plastics implement the “GB 4806.7-2016 National Standard for Food Contact Plastic Products”, and paper implements the “GB 4806.8-2016 National Standard for Food Contact Paper and Cardboard Materials and Products” “, both migration experiments are carried out in accordance with “GB 31604.1 and GB 5009.156-2016”.

It’s safe to cook at 100 degrees for 1 hour, and we don’t have to worry about it when we use it on a daily basis. What you eat every day, usually notover 100 degrees. (Otherwise your mouth will call for help~
And the action of absorbing oil can be done within 1 minute, and it cannot take more than 1 hour.
So, as long as the product meets the national standard, we use it to suck the oil in takeout, or throw a piece of cooked soup or cooked dish to suck a piece of it. It’s safe to inhale.
China Packaging Research and Testing Center has tested 3 types of food absorbent paper, which are safe to use at 80 degrees and 100 degrees.

But be careful, don’t drop the blotting paper directly into the boiling oil! When the temperature exceeds 100 degrees, the safety of the blotting paper cannot be guaranteed.
Also when frying chicken wings in the oven and air fryer, heating dishes in the microwave, etc., the temperature will exceed 100 degrees, and do not put absorbent paper in the cooking process.

Some people may want to ask: I have ready-made kitchen paper at home, can I replace food absorbent paper?
The answer is no.
Although many kitchen paper will also be marked with “food grade” and “can come in contact with food”, it is safe to touch food at room temperature, but it may be risky to touch food at high temperature.
The key is: kitchen paper standards do not limit the total migration of harmful substances at high temperatures.
The standard of oil-absorbing paper has a limit on the total migration of harmful substances at high temperature, while the standard of kitchen paper does not have this item, and only limits the microorganisms of paper towels.

It’s fine to wipe raw steaks and cooked dishes with food-contact paper, but it’s not safe to put them in hot soups or hot dishes. That’s not what people use to do this!

Finally, I would like to emphasize that oil-absorbing paper should come into contact with high-temperature food, and it should not be bought randomly.
It depends on the packaging of the product (for online shopping, you can see the details page, or the product packaging in the buyer’s show), plastic oil-absorbing paper, and look for “GB 4806.7-2016” This standard; paper oil-absorbing paper, look for the standard “GB 4806.8-2016”.

Of course, having said that, oil is not our enemy, and it is necessary to consume a moderate amount of oil every day.
However, when the takeout is too greasy, the soup is too oily, or the last meal is too oily, you can use oil-absorbing paper to help reduce oil.
There are also parents who have high blood lipids, or babies who cannot eat too much oil. It will be much more convenient to have oil-absorbing paper.
Family eats at the same table, and can scoop the soup into a bowl to DIY the greasy level, so there is no need to quarrel for too much oil~
Having said so much, how could it be possible without the recommendation of “easy to use oil-absorbing paper”!
We have sorted out a —
Recommended list of blotting paper
Just follow the instructions and buy it, it’s super worry-free!
