Is the bag containing medicinal tea poisonous? Many tea bags are disposable, and many friends who love tea will bring a tea bag with them, which is convenient for drinking their favorite tea anytime and anywhere. Let's share with you whether the bag containing medicinal tea is poisonous.
Is the bag containing medicinal tea poisonous? 1 The tea bag in the tea bag is not poisonous. Generally speaking, tea bags in teabags meet food safety requirements and are harmless to our health. Everyone can rest assured to drink teabags.
Teabag has the advantages of cleanliness, convenient slag discharge, convenient mixing and portability. Meet the needs of modern people's fast-paced life.
Generally speaking, tea bags in teabags have the following forms: nylon filter cloth, cotton yarn, PET yarn, PLA degradable fiber and composite fiber.
Among them, cotton tulle is the earliest used packaging material, mainly composed of plant cellulose, but the packaging performance of processing will become worse.
Nylon filter cloth is a new type of packaging bag, a colorless and tasteless food-grade nylon filter bag with good vision.
PLA degradable fiber is mainly made of plant starch, which is decomposed by natural soil to produce carbon dioxide and water. It is a green filter material in line with the current environmental protection situation.
Generally speaking, this kind of teabag has biocompatibility, no toxic and side effects, and has two functions of bacteriostasis and mildew prevention.
Finally, the composite fiber material has higher boiling water brewing ability, but this fiber may have certain health risks.
Is the bag containing medicinal tea poisonous? Tea bags can be sold in the market, and they are generally subject to heavy control and testing. Therefore, buying tea bags in big stores is generally not toxic, and using tea bags correctly will not release harmful substances into tea soup. In addition, making tea with tea bags is convenient and quick, and will not affect the taste experience. Nowadays, many people buy teabags.
What material is good for tea bags?
Cotton tulle
Tip: The above content comes from the arrangement and originality of this site. The key topic recommended to you in the next issue is: how to brew jade tea? Let's continue to introduce this topic in depth.
Cotton tulle is one of the most common and earliest materials used in tea bags. Mainly composed of plant fibers, it is safe, non-toxic and reusable. However, the tea bag made of pure cotton tulle may be poorly packaged.
Nylon filter cloth
Nylon filter cloth is a relatively new teabag material. Colorless and tasteless food-grade nylon filter cloth teabag has the characteristics of high transparency. Even if you use a tea bag made of this material, you can still enjoy the wonderful tea spread gradually.
Degradable fiber
Protecting the environment is everyone's responsibility. As small as tea bags, we can choose tea bags with degradable fibers. The raw material of this tea bag is plant starch, which is very environmentally friendly, so don't worry about damaging the environment. Through the decomposition of natural soil, carbon dioxide and water can be formed and a virtuous circle can be realized. The only drawback is that it is a bit expensive.
Choosing high-quality tea bags will not be toxic. On the contrary, if it is inferior tea bags, it may emit certain toxicity. When buying tea bags, you should not only choose better materials, but also buy them in regular stores to avoid buying inferior tea bags.
Is the bag containing medicinal tea poisonous? 3 the origin of teabags.
It is said that in 1904, there was a businessman named Thomas Sullivan in new york, USA. In order to expand sales, he tried to send tea samples in Suu bags to buyers. After receiving the sample, a buyer accidentally forgot to soak it in a cup with a silk bag, and the result was completely unexpected-his customer thought it was more convenient to use the tea in Suu bag. Clever Sullivan got inspiration from it, and soon made a small bag with a thin layer of gauze instead of silk, and introduced a new type of tea packed in small bags, which opened the tea bag industry.
Now only in Britain, people drink about 65.438+0.3 billion cups of tea bags every day, and every British person drinks more than 4 cups of tea every day, of which 96% are tea bags. Teabag is popular in the international market because of its advantages of rapid brewing, cleanliness, standard dosage, mixed drinking, convenient slag discharge and portability, which can meet the needs of modern people's fast-paced life.
The material of teabag
1, silk cotton tulle
This should be the earliest packaging material used to make teabags, and it is rarely used now. The main chemical component of silk is protein fiber (composed of amino acids), while cotton yarn is plant cellulose (macromolecular polysaccharide, the main component of plant cell wall). Generally, both of them are harmless to human body, but the processing and packaging performance is poor.
2, nylon filter cloth
Nylon is a polyamide fiber. Colorless and odorless food-grade nylon filter bag meets the national hygienic standard for food packaging. Through its transparent high-quality heat-resistant mesh fabric, you can see the real material of tea. It is a new type of tea packaging filter material that ordinary filter paper tea bags can't match.
3. Polyester yarn
PET is the abbreviation of polyethylene terephthalate, which is a kind of polyester fiber. As a tea bag packaging, it has the characteristics of high texture and transparency, excellent bag-making and shape-keeping. Generally, there is no dissolved substance during soaking, which is harmless to human body and environment. However, this kind of fiber has relatively poor tolerance to pH at high temperature, and may not be suitable for brewing some tea.
4. Polylactic acid degradable fiber
PLA degradable material made of plant starch can be decomposed into carbon dioxide and water in natural soil. It is the most promising new generation of sustainable green filter material, leading the international tea drinking fashion, and will become an irresistible trend of tea packaging in the future. PLA fiber is biocompatible and can be safely implanted into human body, so it generally has no toxic or side effects. At the same time, PLA also has antibacterial and mildew-proof effects.
5. Other composite fibers
Because the packaging performance of filter paper or natural plant fiber is poor, it can be compounded with some synthetic polymer fibers to make packaging bags, such as heat-sealed filter paper compounded with polyvinyl acetate and polyvinyl chloride fibers, such as compounding with some resins to improve the boiling water brewing resistance of filter paper. This kind of fiber may pose a high health risk to human body.
Generally speaking, the popular tea bags on the market are made of materials that meet the requirements of food-grade packaging. Judging from the main materials, it is generally harmless to human body. However, we must be aware of various additives, such as solvents, initiators, bleaches, etc. , commonly used in the synthesis of materials, harmful to human health. Therefore, packaging requires high cleanliness of materials, and general tea enterprises will certainly not pay attention to cleanliness and other indicators when purchasing packaging materials.
Although there are subtle differences in the use conditions of various tea bag packaging materials, ordinary consumers generally cannot distinguish them. Therefore, we should keep in mind the following principles: try not to brew tea bags at high temperature for a long time, choose regular brand tea bags, and drink tea bags as little as possible if it is inconvenient.
