What can t you soak in a thermos cup?

Roundup

It is best not to use the thermos cup to make milk, tea, traditional Chinese medicine, honey, and sour plum juice.

Lemon juice, carbonated drinks.

Foods such as dairy products, in short, thermos cups cannot be used to soak acidic beverages, because acidity is prone to chemical reactions with the metal in the thermos cups.

It can cause adverse effects on the human body after drinking.

The purchase of thermos cupsLook at whether the surface polishing of the inner and outer tank is uniform, and whether there are bruises and scratches. Second, see whether the mouth welding is smooth and consistent, which is related to whether it feels comfortable when drinking water. Third, look at the poor quality of plastic parts.

It will not only affect the service life, but also affect the hygiene of drinking water. Fourth, see whether the internal seal is tight. Whether the plug and the cup fit properly.

Whether the screw-in and screw-out are free and whether there is water leakage.

Fill a glass of water and turn upside down.

Four or five minutes or a few hard shakes can be used to verify that there is no water leaking. Looking at the thermal insulation performance, this is the main technical index of the thermos cup. Generally, it is impossible to check according to the standard when purchasing, but you can check it by hand after filling it with hot water, and the lower part of the cup will heat up after two minutes of hot water in the cup that is not kept warm.

And the lower part of the insulated cup is always cool.

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.

Tea (not suitable).: Tea specifically refers to green tea, because it contains a lot of tannins, theophylline, aromatic oils and a variety of vitamins, suitable for brewing with about 80 water. If you use a thermos cup to make tea, the tea leaves are easy to ferment under high temperature and constant temperature conditions, vitamins will be destroyed in large quantities, aromatic oils will be volatilized, and tannic acid and theophylline will be leached in large quantities, which will not only reduce the nutritional value of tea, but also make the tea juice fragranceless and the tea taste bitter.

Precautions for thermos cups.

Because the thermos cup has a thermal insulation effect, especially some of the best thermos cups have a particularly good thermal insulation effect, if the very hot boiling water is put in, it is still very hot boiling water when it is poured out, so the use of thermos cup food medicine to prevent scalding.

It is recommended not to use a thermos cup to fill the soup with greasy liquids, and if the soup is not cleaned in time, there will be a very serious oily smell, and no matter what method you use to get rid of it, it is difficult to remove the greasy smell.

Something that can't be soaked in a thermos cup:

1. Do not use a thermos cup to soak fresh lemons, juice and other acidic substances, because the stainless steel inner wall of the thermos cup contains heavy metals such as cobalt and nickel, and the acidic substances contained in the lemon will react with these heavy metal ions, resulting in the precipitation of heavy metal ions. These heavy metal ions can enter the body as we drink water, damaging our health.

2. You can't soak red dates and fat seas.

Hair objects such as red dates, fat seas and other hair objects will expand after being soaked in hot water, resulting in an increase in air pressure in the thermos cup.

3. Do not soak in milk, milk contains many microorganisms, if placed in the thermos cup for a long time, the microorganisms in the milk will multiply rapidly at a suitable temperature, resulting in corruption, and it is easy to cause diarrhea and abdominal pain after drinking.

4. It is not suitable to make tea. If you use a thermos cup to make tea, so that the tea leaves are soaked in high-temperature, constant temperature water for a long time, just like decoction with a warm fire, a large number of vitamins in the tea are destroyed, aromatic oil volatilization, tannic acid.

A large amount of theophylline leaching not only reduces the nutritional value of tea, but also makes the tea juice fragranceless, the tea taste bitter, and even because the steeping time is too long, the tea may release heavy metal substances, which is harmful to health.

The thermos cup can be used to make tea, sugar water, wolfberry, dates, ginseng, and coffee. The vacuum cup is made of ceramic or stainless steel and a vacuum layer to hold water, with a lid on the top, tightly sealed, and the vacuum insulation layer can delay the heat dissipation of liquids such as water installed inside, so as to achieve the purpose of heat preservation.

Especially in winter, the stainless steel thermos cup is liked by many consumers, because it has a unique thermal insulation effect, generally speaking, the insulation time is as long as 5 12 hours, so it is particularly popular with consumers. The stainless steel thermos cup is to extract the vacuum and air compartment, so as to achieve the purpose of heat preservation.

Take care before use.

After washing with dish soap, wash it several times with clean water to prevent the dish soap from remaining on the wall of the cup. If there is a large smell of dish soap in the cup after washing, you can wash it several times with boiling water, or brew it with tea leaves to achieve the effect of removing the odor.

In addition, in the process of using the thermos cup, it is necessary to avoid collision and impact, so as not to damage the cup body or plastic, resulting in thermal insulation failure or water leakage. When tightening the screw plug, the force should be appropriate, and do not rotate too much, so as to avoid the failure of the screw buckle.

Do not make milk, tea, or Chinese medicine. In fact, the best function of a thermos flask is to keep warm, keep cold or keep warm. Therefore, it is recommended that everyone use the thermos flask as a tool for filling water.

Try not to make things, especially tea. But keeping warm can actually be used to make coffee, but be sure to clean it after use to avoid leaving dirt. In fact, the thermos cup can not only be used to drink water, but also to hold other things.

Attention needs to be paid to the use of thermos cups.

1. Before using the new product, it must be scalded several times with boiling water or detergent for high temperature disinfection. It has achieved the effect of killing bacteria.

2. Please preheat with boiling water for 5-10 minutes before use to make the insulation effect better.

3. Don't overfill the water, so as not to burn the boiling water when the lid is closed.

4. Don't use a thermos cup to make tea.

The things that can't be soaked in the thermos cup are:

1. Dry ice and carbonated drinks.

Dry ice and carbonated beverages should not be placed in the thermos cup to avoid dangers such as rising internal pressure, resulting in the inability of the cork to be opened or the contents to be sprayed.

2. Fluids (such as brine) that should not be salted

Because the inner tank of the thermos cup is sandblasted and electrolyzed, the electrolyzed inner tank can avoid direct contact between water and stainless steel material and physical reaction, while the salt contains corrosiveness that may cause damage to it, and it is not suitable for long-term storage in the cup.

3. It is not advisable to soak traditional Chinese medicine.

Some people also like to soak Chinese medicine in a thermos cup to make it easy to carry and drink. However, the decoction of Chinese medicine generally dissolves a large number of acidic substances, which is easy to react with the chemicals contained in the inner wall of the thermos cup and dissolve into the decoction, which has adverse effects on the human body.

Healthy way with a thermos mug:

1. Don't pack any drink for a long time.

Whether it is water or drinks, it is fresh and the healthiest, and it is okay for office workers to use thermos cups to fill milk, Chinese medicine, etc., but they should still pay attention to drinking as soon as possible.

2. Clean the sealing ring of the cup lid frequently.

Many people think that the thermos cup has good sealing and is not easy to be polluted, but they don't know that the sealing ring of the cup lid is a breeding ground for bacteria, and it is easy to pollute the water in the cup, so it is good to clean it frequently.

For stains that are difficult to remove, you can rinse them with a neutral detergent or wash them with diluted vinegar, and the washing time should not be too long, so as not to damage the passivation film.

3. Cool the boiling water and then put the thermos cup.

No matter which kind of thermos cup you use, it is recommended that you do not pour the freshly boiled water directly into the thermos cup, but can choose to lower the water temperature below 70 and then pour it into the thermos cup.

The thermos cup can be used to make tea, succulated syrup, wolfberry, dates, ginseng, coffee, etc. The vacuum mug is made of ceramic or stainless steel and a vacuum layer to hold water, with a lid on the top, tightly sealed, and the vacuum insulation layer can make the water and other liquids contained inside delay the heat dissipation, so as to achieve the purpose of heat preservation.

Ceramics, English is China. The Chinese invented pottery as early as about 8000 2000 BC (Neolithic Age). Vessels fired with clay are called pottery, and utensils fired with porcelain clay are called porcelain.

Ceramics is a general term for pottery, stoneware, and porcelain. The ancients called ceramics Ou. All utensils made of clay with two different properties of clay and porcelain clay as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics.
