Can I make tea in a plastic cup?

Of course. However, the plastic smell produced by making tea in plastic cups will affect the fragrance of tea itself. As long as it is plastic, some phthalates (plasticizers) will be added to facilitate processing and molding, and it will also be brought into the production process. The solubility of phthalate esters increases obviously with the increase of temperature, and the solubility in oil is greater than that in water.

Although some plastic teacups have qualified marks, they contain many chemical components. Tea is rich in theophylline and is brewed at high temperature. Theophylline has a slight corrosive effect on plastics at high temperature. Generally, plastic teacups can easily emit potential chemicals in the cups at high temperature, which will cause harm to human body. If it is used to make tea, the chemical composition will be aggravated, and some even have chemical effects. Plastics will produce toxic substances when exposed to heat, and will decompose into a thick plastic smell when exposed to high temperature.

Generally, tea needs more than 80 degrees of water to wash out the original taste of tea, but if it is brewed in plastic cups, the taste released by plastic cups will greatly destroy the taste of tea, so it is best not to use plastic cups to make tea. Therefore, it is suggested that tea cups and plastic cups should be purchased from qualified cups or glasses in large shopping malls.

Some plastic cups sold in shopping malls are qualified and some are unqualified. As our consumers, we can only make simple judgments from the surface of goods. For example, look at the trademark, factory name, address, telephone number, raw material texture, certificate of approval, etc. , but also from the sensory identification, to see if there are impurities in the plastic, smell whether pungent and so on.

Generally, a good plastic that can be used for entrance should be resistant to high and low temperatures (I don't know the specific qualification standard), and making tea should generally be no problem, but now the reliability of the product is very low, even the qualified product is not 100% reliable, so for your own health, it is recommended that you choose cups made of glass, porcelain and other materials instead of plastic cups. If plastic cups can only be used under special circumstances or circumstances, and only once or twice occasionally, I think it may not be a big problem. If you use them for a long time, I suggest you use other materials.

Making tea and entertaining guests is a traditional culture in China. The society has changed, so has the tea ceremony. Nowadays, guests come and go, and the trend of making tea with disposable paper cups has developed. "One-time", the subtext is: "You are my one-time friend." "Paper cup", is human feelings like paper? This is a lack of etiquette, a disrespect of the host to the guests, and makes the guests feel the contempt of the host. As the saying goes, "tea gets cold as soon as people leave." It is not good to entertain guests with disposable paper cups, which has the feeling that "the tea will get cold before people leave".
