Polymer materials are also widely used in the food industry; foods need to be protected from spoilage and decay, and polymer materials can help address or solve this problem. There are many types of polymer additives, including thickeners, suspending agents, gelling agents, as well as additives for preservation and anti-corrosion. It extends the shelf life of food to a certain extent, but various food safety incidents have been caused by additives. **Regulations regarding additives have also been introduced on numerous occasions, which still gives people the impression that any additive is harmful. The application of polymer materials in the food industry refers not only to additives but also to new types of tableware that are made from polymer materials. Such as chopsticks, lunch boxes, instant noodle containers, and melamine tableware. (This has already been explained.) Non-stick pans use polytetrafluoroethylene as their bottom coating, taking advantage of its excellent thermal properties, chemical resistance, ease of cleaning, and non-toxicity. Some polymers are added to dishwashing detergents as cleaning aids to improve their performance. The addition of polymers can enhance the detergency of active ingredients, resulting in better detergent performance. Also, the packaging bags for seasonings these days are all made of polymer materials. So, to repeat the same point: we cannot avoid polymer materials. First and foremost, we need to understand and become familiar with them, use them correctly, and make full use of their excellent properties.
I used to drink a quick-service milk beverage from a certain brand; it had a pleasant thick texture, and I really liked that. Later, I found out that thickeners were added to it, so I stopped drinking it
I’m actually very curious about the mental state of the engineers at the manufacturers that produce such products, for example, those who make Sudan Red
Yes, plain boiled water is the best; even drinks in which the tea leaves are not visible should be used with caution.
Yes, I don’t drink tea-based beverages anymore since I saw that ingredient list
Non-stick pans use polytetrafluoroethylene as their bottom coating, taking advantage of its excellent thermal properties, chemical resistance, ease of cleaning, and non-toxicity. Why are there pits on my non-stick pan that look like corrosion?
Polytetrafluoroethylene is just a coating layer, and if that layer is damaged in certain areas – for example, by a shovel or a metal cleaning ball – pitting will certainly occur.
