Plastic cups, commonly found in daily life, are widely popular due to their lightweight and easy to manufacture characteristics. However, when selecting and using plastic cups, attention should be paid to their material. It is mainly divided into two types: PP (polypropylene) and PC (polycarbonate). PP plastic cups are a safer choice due to their high temperature resistance and resistance to releasing harmful substances. Relatively speaking, cups made of PC material may release bisphenol A (BPA) at high temperatures, which is a potential endocrine disruptor that long-term intake may affect health.
Scientific research has shown that in high-temperature environments, such as brewing with hot water, certain plastic cups may release trace amounts of chemicals. For example, a study found that when using PC plastic cups to hold hot water, the content of BPA in the water significantly increases. Although the release levels of these chemicals are usually below safety standards, long-term accumulation may still have an impact on the body.
Therefore, when choosing plastic cups, it is recommended to prioritize products labeled with “BPA free” or using PP material. During use, avoid prolonged use of hot water or beverages, especially oily and acidic beverages, as these liquids may accelerate the release of chemicals. When cleaning plastic cups, it is best to use warm water and neutral detergent, avoiding the use of hot water and strong cleaning agents to reduce the potential risk of chemicals.
Glass Cup: A Healthy Choice Behind Clear and Transparent Scenes
Glass cups, common and with a long history, are a frequent customer in the kitchen. The main component is silica sand, which is melted and formed at high temperature. Its chemical properties are stable and it is not easy to react with the loaded material. This means that whether it is a cold drink or hot tea, the glass can maintain the original taste of the drink without producing any odor or harmful substances.
A practical example is that when lemon water is loaded into a glass, the acidic components do not cause a chemical reaction. This is different from some plastic cups, which may release trace amounts of chemicals in acidic environments. Similarly, even when loading hot drinks, the glass remains stable and there is no risk of dissolution like some plastic cups.
However, there are also things to pay attention to when using a glass. For example, the physical fragility of a glass cup means it may rupture under impact or sudden temperature changes. Therefore, when using glass cups, it is important to avoid rapid changes from cold to hot to prevent sudden temperature changes that may cause glass breakage. Although this situation is not common, it is still worth noting in daily use.
Overall, glass cups are a healthy and safe choice due to their chemical stability and odorless properties. Suitable for daily household use, especially when it is necessary to ensure the taste and quality of beverages, glass cups are preferred. Just pay attention to its physical properties and use it correctly, it can add peace of mind and health to daily life.
