[Ten years of great development in chemical technology] 189-2023 Drinking yogurt is no longer a problem* * It's so embarrassing

Thread Content

It is a rare pleasure to drink yogurt in the hot summer. You can only drink 90% of it, and the other 10% is stuck on the inner wall and lid of the package. In order to no longer have* * The lid is embarrassing. Someone invented a new chemical material that does not stick to milk. Give it a try... Has anyone licked the lid of yogurt? Anyway, kids really like it. It feels like there is always endless yogurt, but whether to lick or not to lick is really a bit confusing, especially for adults. Why does yogurt stick to the lid? Yogurt is a liquid that has a small "contact angle" with the yogurt lid and has a relatively strong wetting ability. Therefore, during transportation and storage, the yogurt easily soaks into the inner surface of the lid, that is, it "sticks to the lid." How to solve it? In recent years, a company in Wenzhou, Zhejiang Province invented milk-free yogurt caps and is said to be able to sell 100 million pieces a year. People's living standards are improving, and new chemical materials companies are paying more and more attention to small details of life and developing products to solve pain points. It is understood that the surface of this yogurt cap has been treated with micro-nano structures, making it hydrophobic and food safe. The lid is non-stick and you can drink the yogurt without licking the lid. Have you ever purchased yogurt packaged in this way?
