Thermos cups explode? Be careful not to soak the food like this!

There was a news report: the girl forgot to drink the red date water in the thermos cup, and opened it more than ten days later, the cup exploded instantly, causing the girl's right eye ball to break.

Why do red dates explode in thermos cups? What other foods don't fit in a thermos cup? How to choose a thermos cup? Let's find out.

Why does good food make a thermos explode?

Because these foods are rich in nutrients, a long soak will cause microorganisms to proliferate, thereby metabolizing gases such as carbon dioxide. If placed for a long time, these gases are continuously compressed in the small space and strong sealing cup, resulting in greater pressure on the inner wall of the cup, and the pressure is released instantly when opened, which may cause an "explosion".

Not only red dates, like wolfberry, longan, tremella, etc., are very suitable for microbial survival, so when using a thermos cup to soak things, do not soak for a long time, if you accidentally forget, you should also be extra careful when you screw the cap.

In addition, not all food is suitable for the thermos cup, such as the most frequently brewed tea.

Because the water temperature of the tea is very high, the tea is stuffy for a long time in the state of high temperature, and the active ingredients such as flavonoids and vitamin C in the tea will be transformed and the content will decrease, which will not only affect the nutritional value of the tea, but also increase the bitterness of the tea and affect the taste.

Some parents like to put hot milk and soy milk in a thermos cup for their children to drink at school. This is not recommended either!

If it is OK to drink in a short period of time, but for a long time, it is easy to deteriorate, such as milk at the appropriate temperature, 3 to 4 hours will produce a lot of microorganisms, and the child may drink diarrhea, abdominal pain and so on.

So those perishable food, it is best not to put into the thermos cup oh ~

After introducing how to use the thermos cup, let's talk about how to choose the thermos cup. Because the inferior thermos cup will let you drink not hot water, but poisoned water.

How to choose the right thermos cup?

There will be heavy metals in most inferior thermos cups, if the long-term drinking of the water inside, may cause decreased immunity, loss of appetite, neurasthenia, may also cause respiratory diseases, such as chest tightness, cough, etc., if the child is still in the development period with such a thermos cup, the harm may be greater.

Therefore, when buying a thermos cup, choose according to this standard:

Select the inner liner, check 304, 316

The most important thing is to look at the inner liner material, the inner liner on the market is mostly stainless steel, the most common 201, 304, 316, but not these three models of stainless steel can be used for the thermos cup:

304: It is an internationally recognized food-grade stainless steel, and there is no problem for families to fill water with food. Some products will be labeled 304 (18/8), which means that the stainless steel material composition contains 18% chromium, 8% nickel, is in line with the thermal cup liner material standards.

Therefore, it is generally enough to choose a thermos cup of 304 inner liner material.

Generally, manufacturers will mark the stainless steel model to the bottom of the liner, but some will mark it to the certificate and manual

316: belongs to the medical grade stainless steel, its corrosion resistance is better than 304, if mistakenly loaded acidic drinks will almost not cause corrosion and heavy metal seepage.

Of course, there are drawbacks, that is, the price is relatively expensive, conditional or choose 316 material.

201: This material is not recommended, 201 stainless steel acid resistance, alkali resistance is much weaker, often used in industry, construction, belongs to the industrial application more. If 201 is used in edible utensils, the utensils will oxidize and rust for a long time, and the heavy metals produced will seriously harm human health.

If the purchase of thermos cup is marked with 201 directly pass, this is the unqualified thermos cup produced by the black heart manufacturer!

Smell plastic, look for environmentally friendly materials

Cup lid, straw these plastic parts can not be ignored, must choose food grade silicone, TRITAN (copolyester), PP (polypropylene) and other safety and environmental protection grade materials made, and these materials are almost no odor, if you open the newly bought cup has a strange taste, it must be a secret, it is best to give up decisively!

Touch the temperature, look for no heat dissipation type

The thermos cup is composed of a double-layer structure of an inner liner and a layer of the cup body, and the vacuum state is between the two layers to achieve thermal insulation. A qualified thermos cup can hold heat for 6 to 8 hours.

However, if the newly bought thermos cup is poured into hot water and can feel the temperature on the surface after a while, it means that it has not been vacuumed and cannot be kept warm at all. This is not insulated "thermos cup", do not buy worth mentioning.

Feel the material, rough feel should not be desired

In fact, most of the cups, the quality is not good, a hand probably know.

Good quality thermos cups, most of the cup body thick, feel smooth and neat, and inferior general cup walls are thinner, and the surface is rough, feel is very poor.

Finally, after choosing a suitable thermos cup, the most important thing is to pay attention to daily cleaning oh ~ No matter what is inside, it is easy to breed bacteria in the appropriate temperature, so it is best to clean it every day and maintain health in order to be healthier!
