Fructose sweetness is about 2.4 times of glucose. So, what fruit is sweet, not only to contain much sugar, the most important is what is inside the sugar, and sugar ratio. For example, eat sweet watermelon sugar content of only 6.2%, because of the high proportion of fructose, and eat no apple sweet watermelon sugar content reached 10%.
