Coffee can be an antioxidant. Drinking coffee regularly has benefits.

Recently, researchers from Monash University in Australia collaborated with an Italian coffee company to study the changes in free radicals and antioxidants in coffee during the coffee making process. Recently, the study was published in the international academic journal Plos One. The researchers gained an in-depth understanding of the coffee roasting process and elaborated on the health benefits of coffee.

Free radicals are unstable molecules that can gain stability by acquiring electrons. Free radicals in the human body can cause cell and DNA damage. Researchers observed free radicals in the coffee roasting process and found for the first time that under certain conditions, coffee can act as an antioxidant and help stabilize free radicals.

"Dr Troup was the first scientist to discover that coffee contains free radicals, so we worked with Dr Troup to conduct an in-depth study on the changes in free radicals and antioxidants in coffee," said Dr Navarini from an Italian coffee making company.

"The most important goal of this study is to gain a deeper understanding of the stabilization of free radicals during coffee roasting and to further explore the antioxidant properties of coffee. We also intend to analyze and prove the components in coffee that have antioxidant properties."

"We studied the changes in stable free radicals and antioxidant compounds in Arabica coffee beans themselves and during the roasting process," said Dr Troup from Monash University.

Taken together, this study provides important information about the potential health benefits of coffee, while also giving us a deeper understanding of the roasting process.
