2. 白巧克力不是巧克力

Because it doesn't contain cocoa solids or chocolate liquor, white chocolate isn't chocolate in the strict sense. But it does contain parts of the cacao bean—mainly cocoa butter.

10. 巧克力的熔点比较特殊

According to the Library of Congress, chocolate has a melting point between 86°F and 90°F, which is just below the human body temperature. That’s why your favorite candy bar will melt in your hands if you don't eat it fast enough.

根据美国国会图书馆的数据，巧克力的熔点在86到90华氏度（30到32摄氏度）之间，略低于人体温度。这就是为什么如果你吃得不够快，你最喜欢的巧克力棒就会在你手融化。
