Abstract: Caffeine, C8H10N4O2, 1,3,7-trimethylxanthine, is a biological basic compound. It is mainly distributed in the young tissue parts of tea, coffee beans and other plants. Caffeine is not only widely used in medicine, but also common in food, such as soft drinks, tea, coffee and other drinks that contain caffeine. Caffeine can promote blood circulation, eliminate fatigue, and excite the central nervous system, but excessive addition can also cause local ischemic heart disease and arrhythmia. Therefore, caffeine content is also an important indicator of beverage quality.Summary: Caffeine content is also an important indicator of beverage quality.References: https://www.alfachemic.com/testinglab/industries/coffee-analysis.html
