Do you like slime? Well, cows have something called submaxillary mucin, which is a slimy substance inside their mouths. Scientists use this slime to create a special coating that can cover different things like medicine or even food!
The coating can help protect these things from getting damaged or broken down too quickly by your body. Imagine covering your favorite toy with a big, gooey layer of slime that can protect it from scratches and bumps.
In the same way, this coating can help protect medicines from being damaged by digestive juices in your stomach or help make sure the flavor in your favorite food lasts longer.
So, scientists take the slimy substance from cows and use it to create a strong and protective coating to keep things safe and sound!
