Do you often use a thermos cup to make tea and traditional Chinese medicine? Have you ever heard of the saying that a thermos cup may be "poisonous"? Today, let's find out to see whether these rumors are true or false.
First of all, let's take a look at why thermos cups should not be used for tea. Tea is rich in a variety of nutrients and aromatic substances, but the high temperature environment of the thermos cup is easy to destroy these valuable ingredients, so that the nutritional value of tea is greatly reduced. In addition, when tea leaves are soaked in water for a long time, they will release too many tea polyphenols and heavy metal substances, which will have a negative impact on human health. Therefore, if you want to drink tea in a thermos cup, it is best to brew it only once, not for a long time.
So, why should the thermos cup not be soaked in traditional Chinese medicine? The composition of traditional Chinese medicine is relatively complex, and some proteins, polysaccharides and other components in medicinal materials will be denatured at high temperatures, affecting the efficacy. At the same time, the decoction of traditional Chinese medicine also has a certain degree of exquisiteness, and long-term high-temperature soaking is easy to destroy the active ingredients of traditional Chinese medicine and affect the efficacy of the medicine. Therefore, if you want to use a thermos cup to carry the Chinese medicine decoction, it is recommended to pour the Chinese medicine decoction into the thermos cup after cooking, and drink it in a short time.
As for the statement that the thermos cup may be "toxic", this is mainly because some unqualified thermos cups may use some materials that are harmful to the human body in the production process, such as chromium, nickel and other elements in stainless steel, or BPA and other harmful substances in plastic. These harmful substances are more easily released in high temperature environments, causing harm to the human body. Therefore, when choosing a thermos cup, you must choose a regular brand and a product with guaranteed quality.
In addition to the above three points, there are some things that need to be paid attention to when using a thermos cup. First of all, try to avoid storing acidic drinks or food in the thermos cup for a long time, because this will accelerate the corrosion of the thermos cup and affect the service life. Secondly, the thermos cup should be cleaned regularly to keep it clean and hygienic. Finally, it is necessary to pay attention to avoid damage to the thermos cup caused by external factors such as falling and colliding.
In short, although the thermos cup is convenient and practical, there are some problems that need to be paid attention to during use. Especially for making tea, making traditional Chinese medicine and material safety, etc., we need to pay more attention. Only the correct use and selection of reliable quality thermos cups can ensure our health and safety.
So, how to choose a reliable quality thermos cup? The following we will analyze in detail from four aspects: material, brand, process and certification.
1. Material
First of all, it is necessary to choose a food-grade 304 stainless steel or 316 stainless steel as the main material of the thermos cup. These two stainless steel materials have excellent corrosion resistance, high temperature resistance, and are harmless to humans. In addition, the plastic liner should choose PP, PES and other food-grade materials to ensure safety.
2. Branding
Choose a well-known brand or a brand with a good reputation, you can buy a reliable quality thermos cup with more security. Some internationally renowned brands such as thermos, Tiger, Zojirushi, etc. have high visibility and reputation in the field of thermos cups, while domestic brands such as Tupperware, Lock & Lock, etc. also have good performance.
3. Craftsmanship
Good craftsmanship can ensure the performance and life of the thermos cup. It is necessary to choose a thermos cup with smooth internal and external surfaces and no flaws, and also pay attention to aspects such as sealing performance and opening method. In addition, you can also observe the appearance details of the thermos cup, such as whether there is an anti-hot hand design, whether it is easy to carry, etc.
4. Certification
Choosing a thermos mug that has passed the relevant certification can ensure its quality and safety more guaranteed. For example ISO9001 quality management system certification and ISO14001 environmental management system certification are effective guarantees for product quality and safety.
