The thermos cup injured the girl's eyeball, just because she soaked dates in the cup? Attention! Don't soak these foods like this

"When you reach middle age, you have no choice but to put wolfberries in your thermos."

Well! I don’t mean to emphasize age here~ But for those of you who believe in wild health, who doesn’t have tea, wolfberry, and jujube in their thermos?

Everyone knows that the health-preserving method can help you maintain your health! But there may also be potential dangers...

There was a news report: A girl forgot to drink the red dates water in her thermos cup. When she opened the cup more than ten days later, the cup exploded instantly, causing the girl's right eyeball to rupture.

Why do red dates explode when soaked in a thermos? What other foods are not suitable for thermos? How to choose a thermos? Let's find out.

Because these foods are rich in nutrients, long-term soaking will cause microorganisms to multiply and metabolize gases such as carbon dioxide. If left alone for a long time, these gases will be continuously compressed in the small space and strong sealing of the thermos cup, exerting greater pressure on the inner wall of the cup. When opened, the pressure will be released instantly, which may cause an "explosion".

Not only red dates, but also wolfberries, longans, white fungus, etc. are very suitable for the survival of microorganisms. Therefore, when soaking things in a thermos, do not soak them for a long time. If you accidentally forget, you must be extra careful when screwing the lid.

In addition, not all foods are suitable for putting into a thermos cup, such as the most commonly brewed tea.

Because the water temperature for brewing tea is very high, and the tea leaves are soaked in high temperature for a long time, the active ingredients in the tea, such as flavonoids and vitamin C, will be transformed and their 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 or soy milk in a thermos cup and let their children take it to school. This practice is also not recommended!

It's okay if you drink it within a short period of time, but if it's left for a long time, it will easily go bad. For example, milk at a suitable temperature will produce a lot of microorganisms within 3 to 4 hours, and if children drink it, it may cause diarrhea, abdominal pain, etc.

So it’s best not to put perishable foods into a thermos cup.

After introducing how to use a thermos cup, let's talk about how to choose a thermos cup? Because a low-quality thermos cup will make you drink poisonous water instead of hot water.

Most low-quality thermos bottles contain excessive amounts of heavy metals. If you drink the water in them for a long time, it may cause decreased immunity, loss of appetite, neurasthenia, and may also cause respiratory diseases such as chest tightness and cough. If such thermos bottles are used for children who are still in the developmental stage, the harm may be even greater.

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

Choose liner, choose 304, 316

The most important thing about a thermos is the material of the liner. Currently, most of the liner on the market are made of stainless steel, the most common of which are 201, 304, and 316. However, not all of these three types of stainless steel can be used for thermos:

304: It is internationally recognized food-grade stainless steel, and it is completely fine for household food and water. Some products are marked with 304 (18/8), which means that the stainless steel material contains 18% chromium and 8% nickel, which meets the standard for the inner liner of a thermos cup.

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

Generally, manufacturers will mark the stainless steel model on the bottom of the inner tank, but some will mark it on the certificate and instruction manual.

316: It is a medical grade stainless steel. It has better corrosion resistance than 304. If it is accidentally filled with acidic drinks, it will hardly cause corrosion and heavy metal leakage.

Of course, there are also disadvantages, that is, the price is relatively expensive. If conditions permit, it is better to choose 316 material.

201: This material is not recommended. 201 stainless steel is much weaker in acid and alkali resistance and is often used in industry and construction. If 201 is used in tableware, the tableware will oxidize and rust over time, and the heavy metals produced will seriously endanger human health.

If you see the label 201 when shopping for a thermos, just pass it up, as it is an unqualified thermos produced by a black-hearted manufacturer!

Smell plastic and look for environmentally friendly materials

Plastic parts such as cup lids and straws should not be ignored. They must be made of safe and environmentally friendly materials such as food-grade silicone, TRITAN (copolyester), PP (polypropylene), etc. These materials have almost no odor. If there is a strange smell when you open a newly bought cup, there must be something fishy, ​​and it is best to give up decisively!

Feel the temperature and identify the non-heat dissipating type

Thermos cups are made of a double-layer structure with a layer of inner liner and a layer of cup body. There is a vacuum state between the two layers to achieve heat preservation. A qualified thermos cup can keep the heat for 6 to 8 hours.

However, if you can feel the temperature on the surface of a newly bought thermos cup after pouring hot water into it, it means that it has not been evacuated and cannot keep heat at all. It is better not to buy such a "thermos cup" that cannot keep heat.

Touch the material, rough feel is not acceptable

In fact, the quality of most cups can be easily determined as soon as you pick them up.

Most thermos cups of good quality have thick bodies that feel smooth and neat, while those of inferior quality generally have thin walls and rough surfaces, and feel very bad.

Finally, after choosing a suitable thermos cup, the most important thing is to pay attention to daily cleaning. No matter what is inside, it is easy to breed bacteria at a suitable temperature, so it is best to clean it every day and keep it hygienic to be healthier!
