We know that the Flavor of coffee beans refers to the overall feeling of coffee in the mouth.

Among them, the aroma of coffee beans, the aromatic compounds released by these freshly crushed coffee cells, such as esters and aldehydes, evaporate quickly after grinding-compared with coffee beans, the contact surface area with air increases by hundreds of times. Not only does the volatilization of aromatic substances lose, but the oxygen in the air also oxidizes aroma components: for example, it oxidizes fat and produces a rotten smell. Freshly ground coffee powder quickly absorbs moisture from the air, & # 153; increases weight and reduces the extraction rate of coffee. & # 153 investors 153
