Who has low caffeine? Look at bean seeds and baking time

Some people say that mild white coffee has less caffeine and is less harmful than black coffee, but this is not true! Cheng Mingwei nutritionist said, the world's coffee bean varieties are dazzling, currently planted in large quantities and have commercial value to belong to "Arabica" and "Robusta" two varieties, and the market operators in the production of white coffee, mainly choose caffeine accounted for only 0.9% to 1.4% of the raw beans Arabica coffee beans, and non-caffeine accounted for 2% to 3% of the raw beans in the Robusta species, so white coffee contains low caffeine can be established.

However, some people hold the opposite view, arguing that "deeply roasted coffee beans have less caffeine." Cheng Mingwei nutritionist explained that in terms of process, caffeine boiling point 178℃, melting point 235℃, roasting coffee temperature range covers 178℃ boiling point temperature, but it is not easy to reach the melting point temperature, so the longer roasting, there is indeed a small part of caffeine will volatilize reduced, but at this time the weight of coffee beans will also decrease with caffeine and become lighter, if take the same weight of deep roasted beans and light roasted beans to brew coffee, drink caffeine content will not be too different.

In short, black coffee or white coffee, which has more caffeine? It depends mainly on what kind of coffee beans are used and whether 2 cups of coffee are equivalent when compared. If the same variety is used, there should be no significant difference in caffeine content between black and white coffee.
