Milk and coke are common drinks in our daily life. What kind of chemical reaction will happen when we put milk and coke together? Mixing coke and milk will produce a lot of sediment. Many people say it's calcium carbonate and will stone when we drink it.
If you think about it a little bit, it's not reliable. The calcium content in milk can't produce so much calcium carbonate. Most of the precipitates are produced by denaturation of proteins in milk. Even if there is a small amount of calcium carbonate, gastric acid can be broken down, not related to stones. Therefore, milk and coke can drink, not dead, but it seems unnecessary to drink it deliberately
First, we slowly pour the milk into the coke bottle.
Then wait for an hour to see what it will become.
How can this be? We can see that a transparent zone will gradually form in the bottle, the color of Coke will be lighter and lighter, and it will be precipitated to the bottom of the bottle, and the sediment will be more and more, the visual effect is very & hellip; & hellip; shocking and full of magic!
Dong Wenhong, a master of nutrition and food hygiene from Peking University, said that milk and juice or coke meet to produce precipitation, a process that has a special term in Food Chemistry: protein denaturation. Protein denaturation is not only not harmful to our health, but also can promote food digestion and help prevent diseases.
Protein is composed of amino acids. Think of amino acids as beads. Thousands of beads are strung into a necklace. Then they are circled and folded in a certain way to save space and play a role. This is a protein with biological activity. However, once encountering strong acid, strong base, high temperature, vibration and other conditions, the folding structure of protein is destroyed, that is, protein denaturation.
Although drinking coke with milk will not affect your health, it is not recommended to try it. It will affect the taste and nutrition of milk.
