There are a lot of myths and legends surrounding coffee. One of them is that coffee beans can melt. Is it true?
The answer is no. Coffee beans cannot melt.
A coffee bean is the seed of a coffee plant. It is the coffee bean that is roasted and ground to make coffee.
The coffee bean is the seed of the coffee fruit. It is a small, dark brown bean with a smooth surface. It is not possible for coffee beans to melt because they are not made of plastic or wax.
Coffee beans are made of cellulose, a type of natural fiber. Cellulose is not susceptible to melting, even when exposed to high heat. In fact, coffee beans have a very high burning point. They will only start to burn at temperatures above 400 degrees Fahrenheit. That means that coffee beans will not melt, even if you put them in a hot oven or coffee maker.
The beans are surrounded by a coffee husk, which is also known as the coffee parchment. The coffee husk is a thin, papery layer that protects the coffee bean. When coffee beans are roasted, the coffee husk burns off and the coffee bean expands. This is why roasted coffee beans are larger than unroasted coffee beans.
The expansion of the coffee bean during roasting is caused by the heat breaking down the cell walls of the coffee bean. This process is called pyrolysis.
Pyrolysis occurs when molecules in a substance are broken down by heat. The word comes from the Greek words pyro, meaning fire, and lysis, meaning to break.
So, the next time someone tells you that coffee beans can melt, you can confidently tell them that they are wrong! coffee beans may be small, but they are tough little seeds that can withstand a lot of heat. So go ahead and enjoy your coffee, knowing that your coffee beans will never melt.
