Thomas Hofmann of Technical University of Munich in Germany decided to study the bitterness of coffee.
He filtered the brewed coffee and found that some of the molecules with the smallest molecular weight tasted the bitterest. So he started to focus on this.
After a series of experiments, he found that one of the molecules was chlorogenic acid lactone (chlorogenic acid lactone). Green
The original acid exists in most plants and becomes chlorogenic acid lactone after dissociation. So they analyze a series of different
Roasted coffee to test the content of chlorogenic acid lactone.
They found that roasted coffee beans break down chlorogenic acid into chlorogenic acid lactone, giving the coffee a mild bitter taste. Succession
The result of continuous baking will decompose chlorogenic acid lactone into phenyllindane (phenylindanes), which will produce a strong bitter taste.
The findings were presented at this year's American Chemistry Annual meeting.
In addition to increasing our understanding of coffee, coffee may be more interested in knowing the source of coffee bitterness.
Manufacturer. From this study, they may be able to find ways to reduce the bitterness of coffee and make it acceptable to more people.

True Blue Mountain Coffee at an altitude of 1800? Coffee trees of this height can hardly survive.
Recently, when I looked up the information on the Internet, I saw a lot of information saying that on the top of more than 1800 of the Blue Mountains, there is only one manor, that is, Amber, which is of Chinese descent. The owner of the manor is Lyn (Lin), originally from Guangdong, China. I think there may be a bit of a mistake here, because coffee trees can hardly survive at a height of 1800 meters. Jialumeng Coffee once asked Zhuang during its meeting in 2007.
