From a scientific point of view, what drinks are not suitable for long term storage in a thermos cup

Dairy products, teas, acidic drinks, traditional Chinese medicine, etc. are not suitable for long-term storage in a thermos cup。Many people like to put drinks in the thermos cup, the purpose is to drink warm liquid at any time, and it is also very convenient to carry, in fact, from a scientific point of view, there are many drinks that are not suitable for a long time in the thermos cup, this is because after the long-term heating of the thermos cup, it may cause the drink to spoil, nutrient loss and other problems.

1. Dairy products.

Dairy products are not suitable for being placed in a thermos cup, because milk contains a lot of protein, and the best storage environment is a low-temperature sterilization state, which will make the microorganisms in the milk multiply indefinitely, resulting in milk spoilage, abdominal pain and diarrhea after drinking. Moreover, the acidic substances in the milk may react with the metal of the thermos cup, which is not conducive to health.

2. Tea. Tea usually contains a substance called tea polyphenols, which can play a certain role in our body, but if it is heated at high temperature for a long time, it may lead to the loss of nutrients, making the tea dull and dull, and the taste will become bitter. Drinking this kind of tea not only does not provide health care, but it will cause harm to our body, and even the taste will be greatly reduced.

3. Acidic drinks.

The inner wall of the thermos cup we use is usually made of stainless steel, which can have a good thermal insulation effect, but it is easy to produce chemical reactions when encountering acidic substances, such as lemon juice, orange juice and so on. The acidic content in these acidic drinks is relatively high, which will react with stainless steel metal, making the thermal insulation function of the thermos cup worse, and will also give birth to harmful heavy metals, which is extremely bad for our body. The same goes for carbonated drinks, try not to put them in a thermos cup.

4. Traditional Chinese medicine. People often say that the purpose of soaking wolfberries in a thermos cup is of course to maintain health, but traditional Chinese medicine is easy to deteriorate when soaked in a thermos cup for a long time. Moreover, some traditional Chinese medicines are acidic and alkaline, which can corrode the inner wall of stainless steel thermos cups.

Fruit juice and carbonated drinks should not be placed in the thermos cup, otherwise it will cause the juice to breed bacteria, and carbonated drinks will also corrode the thermos cup. In addition, try not to make tea in the thermos cup.

First, carbonated drinks, second, milk, third, drinks, fourth, orange juice drinks, fifth, Coca-Cola, these will react with the material inside the thermos cup.

Goji berry tea, jujube tea, cola, sprite, Fanta. These gas-prone drinks are not suitable for long-term storage in a thermos cup.

No, it is because the coffee contains acidic substances, which will react chemically with the materials in the thermos cup and endanger human health.

Coffee contains an ingredient called tannins, which over time can corrode the inner walls of the thermos, even in electrolyzed thermoses. Damaged thermos cups may also have chemical reactions that affect health.

It is not recommended to use a thermos cup for coffee, because the material of the thermos cup may react chemically with the substances in the coffee, and the coffee will affect the taste after being placed in the thermos cup.

Health hazards: Some thermos cups can hold coffee, and some materials can't hold coffee, such as stainless steel thermos cups. Because there is a substance called tannic acid in coffee, tannic acid will react in the stainless steel thermos cup, causing damage to the thermos cup, and may also produce chemical effects that may harm health.

Difficult to clean:

The color of the coffee is relatively dark, and if the thermos cup that has been brewed in coffee is not cleaned in time, it may cause pigment residue, which is difficult to clean, and there are many thermos cups now, and some peculiar shapes are even more difficult to clean.

The thermos cup should not be installed:

1. Milk. Milk is highly nutritious and many people drink it at any time, however, because milk is highly nutritious, vitamins and other nutrients are easily destroyed at high temperatures, and microorganisms are also prone to multiply quickly at the right temperatures, leading to spoilage. It can easily cause diarrhea and abdominal pain.

2. High acidity juice. The juice can not be kept high enough to prevent damage to the vitamins. In addition, high-acidity juice is easy to react with the inner wall of the thermos cup, which affects human health.

Summary. Carbonated drinks are acidic liquids, while thermos flasks are things that cannot be filled with acid. If the inner container of the thermos cup is made of high-manganese steel and low-nickel steel, it cannot be used for acidic beverages such as fruit juices or carbonated drinks.

The material has poor corrosion resistance and can easily precipitate heavy metals when exposed to acids. Long-term acidic beverages may harm human health. In addition, the juice is not suitable for high-temperature storage, so as not to destroy its nutrients; Beverages with a high sweetness can easily lead to microbial growth and deterioration.

Carbonated drinks are acidic liquids, and the thermos bottle is something that can be filled with acid. If the inner container of the thermos cup is made of high-manganese steel and low-nickel steel, it cannot be used for acidic beverages such as fruit juices or carbonated drinks. The material has poor corrosion resistance, and it is easy to precipitate when exposed to acids, and it is resistant to early heavy metals.

Long-term acidic beverages may harm human health. In addition, the juice is not suitable for high-temperature storage, so as not to destroy its nutrients; Beverages with a high sweetness can easily lead to microbial growth and deterioration.

It will destroy the thermos cup.

But if you don't want to use the thermos cup anymore, you can install it.

Summary. Hello dear, it is not recommended to put carbonated drinks in the thermos cup, even if it is not kept warm.

Hello dear, it is not recommended to put carbonated drinks in the thermos cup, even if it is not kept warm.

Dear, the reason why it is not recommended to use a thermos cup to pack carbonated drinks is because carbonated drinks are gaseous things, and the permeability is relatively strong, and the thermos cup is used to prevent water leakage is a kind of plastic called rubber ring, the thermos cup is unable to prevent carbonated drinks from shaking crookedly, especially when the thermos cup is bumpy, the gas of carbonated drinks comes out in large quantities.

Thank you. Moreover, carbohydrate drinks are acidic substances, which will react chemically with the stainless steel material of the thermos cup, resulting in the deterioration and flavor of the drink. And the thermos cup is not hand-style, the rust-resistant steel is affected by oxidation and rust, which shortens the service life of the thermos cup.

1. Carbonated drinks are originally vapor and have strong permeability. The vacuum thermos cup is used to prevent water leakage is a kind of plastic called rubber ring, if the vacuum thermos cup is used to hold carbonated drinks, it is easy to leak. When it is bumped, the vapor bubbles again, and the water leakage of this vapor will be more serious.

2. Carbonated drinks, milk and dairy products are acidic, and acidic substances will have a chemical reaction on stainless steel, resulting in deterioration and flavor of beverages, and stainless steel will be susceptible to oxidation and rust. This situation is also affected by the material of the steel of the thermos cup factory, good stainless steel, less oxidation, poor stainless steel is easy to oxidize.

Most of the <> thermos cups are made of stainless steel, carbonated drinks contain a large number of compounds, in which the carbonic acid can react with iron, and the lid of the cup is shaken to make the gas sprayed out under pressure and dangerous, so the thermos cup can not contain carbonated drinks.

Milk. However, because milk is rich in nutrients, vitamins and other nutrients are easy to be destroyed at high temperatures, and the microorganisms in it are also easy to multiply rapidly at the right temperature, resulting in spoilage, diarrhea and abdominal pain. Juices with high acidity.

The juice should not be kept at a high temperature in the first place, so as not to destroy the vitamins. In addition, fruit juice with high acidity is also easy to react with the inner wall of the thermos cup, which affects human health.

Drinks are generally not suitable for putting in a thermos cup, giving children often drinking milk, fruit juice drinks are not suitable for putting a thermos cup, in addition to carbonated drinks, tea is not suitable for a thermos cup.

The tea we often drink cannot be put in a thermos cup, because the tea leaves are soaked in high temperature for a long time, which will destroy the nutrients in the tea and some harmful substances will be released.

These drinks should never be served in thermos cups.

It is generally known that it is not advisable to use a thermos cup to make tea, which will make the tea lose its original flavor and will also lose a lot of nutrients. However, did you know that thermos cups should not be used to hold the following things: carbonated drinks, milk and dairy products?

1.Carbonated drinks are gaseous things, which are more permeable, and the thermos cup is used to prevent water leakage is a kind of plastic called rubber ring, which cannot prevent carbonated drinks from not being crooked, especially when the thermos cup is bumped, a large amount of gas from carbonated drinks comes out, and the leakage will be more serious.

2.Carbonated beverages, milk and dairy products are all acidic, and the acidic substances will have a chemical reaction on the stainless steel of the thermos cup, which will cause the drink to spoil and taste. Moreover, the stainless steel of the thermos cup will also be rusted by oxide dioxide, which will shorten the service life of the thermos cup.

It is not only harmful to its own substances, but also will damage the thermos cup, it seems that these substances should never be used to contain the thermos cup.
