The hottest experts make tea and use glasses is th

Experts: using glasses to make tea is the healthiest.

in cold winter, making a cup of hot tea at hand is the most refreshing for work. Many white-collar workers begin to use thermos cups after winter. However, recently, a "white-collar health notice" circulated on the Internet, which mentioned that making tea in a thermos cup is carcinogenic. In this regard, food safety and health experts said that this statement is a little alarmist, and it is more dangerous to treat guests with disposable paper cups

it's no good making tea with a thermos.

Mr. Zhou, a white-collar worker who works in Xinjiekou, usually likes to drink tea to refresh himself, because he is afraid of the cold. Recently, he bought a thermos on the, and the tea can remain warm after making tea. Yesterday, a colleague specially forwarded a message to him on his microblog: soaking tea in a thermos cup for a long time in high-temperature water will destroy the vitamin in it and increase carcinogens. Mr. Zhou was not lightly frightened: after drinking the tea made in the thermos cup with symmetrical front and rear columns for half a month, isn't it the high-risk group

who had the same experience as Mr. Zhou, and he was sent to the provincial metrology institute or the National Metrology Institute to determine the matter, Mr. Wang, "I make tea in the thermos cup every winter, have I been using it wrong all the time?" moreover, Mr. Wang also had a question: don't use the thermos cup to make tea, then use other containers to make tea, How to keep water warm

experts: there is no final conclusion that tea brewing in a thermos cup causes cancer

the hydration reaction of nutrition and food at Nanjing Medical University starts from the surface of cement particles. Mo Baoqing, an associate professor of hygiene, analyzed that brewing tea with boiling water may destroy the vitamins in tea, make tannic acid and theophylline exude in large quantities, and make the taste bitter. However, it is inconclusive that carcinogens will be produced. In many office water dispensers, the temperature of hot water is set at only about 90 ℃. It's not a big problem to make tea with a thermos cup

in fact, compared with making tea in a thermos cup, white-collar workers should be more wary of disposable paper cups. Using this paper cup to make tea for guests is very harmful to health. In addition, plastic products such as plastic cups, bowls and buckets have been widely used in life, but they are also relatively unsafe. "Most plastic products have a triangle with arrows at the bottom, and each number represents different materials. For example, the number in the triangle is' 5 ', which represents polypropylene (PP), which is used to make microwave oven lunch boxes, and can be heated in the microwave oven."

then, in daily life, what kind of cups should we use?

"among cups of various materials, glasses are relatively safer." Mo Baoqing said that because the glass does not contain organic chemicals during the firing process, there is no need to worry about chemicals being drunk into the stomach when drinking water with the glass. When choosing tableware for your baby, it's best not to use plastic products. Glass milk bottles, porcelain bowls, stainless steel bowls and so on are better choices

manufacturer: the tea making time of thermos cups should not be too long

yesterday afternoon, I contacted a manufacturer of thermos cups in Wuhan. A staff member surnamed Wu said that most of today's thermos cups are insulated in a closed way. No matter what brand of thermos cups they are, they should not be used to make tea for a long time, "The structure of tea itself is very special. Once it is closed, it is easy to ferment. After fermentation, tea will produce substances harmful to human body."

Mr. Wu introduced that there are some advanced customized thermos cups in the thermos cups now, which have certain health care functions. For this kind of thermos cup, it is good to drink water directly, and try not to use it for tea or hot drinks

in addition, if you use a mug to make tea, as long as you don't soak it for a long time, it's still some advantages over other mugs. Because tea is rich in protein, fat, sugar, vitamins, minerals and other nutrients, it's a natural health drink for most people. As long as you don't soak it in a mug for a long time, you can drink it healthily

if it is soaked for a long time, the nutrients such as vitamin C in tea will be completely destroyed, and the health care function of tea will be reduced because it is soaked in high temperature for a long time. Not only can tea be soaked in a mug for a long time, but also soup, milk or traditional Chinese medicine can't be soaked in a mug for too long. If you really want to drink tea in a thermos cup, brew it in a teapot. Wait until the tea is warm, and then pour it into the thermos cup to keep warm

Mr. Wu told that a high-quality thermos cup has a good insulation effect, and the things in it will deteriorate due to the continuous high temperature, and even produce substances harmful to the body. Therefore, don't put anything else in the thermos cup for too long except water. At the same time, due to the good heat preservation effect of the thermos cup, the aroma in the tea will quickly volatilize after soaking in the high water temperature, which not only reduces the nutritional value of the tea itself, but also reduces the aroma of the tea and increases harmful substances. "There is still a certain way to use the thermos cup, and you should pay attention to its use." Zhonghua glass () Department
