Why is the watermelon sweeter after it's iced?
Watermelon is the best kind of fruit in the summer, and when you are thirsty, you can eat a piece of watermelon. If you can eat a piece of ice watermelon, it will be sweet and ice feeling better. Why ice watermelon will be sweeter? Let's find out the mysteries.
Eat watermelon in the summer, iced sweeter and better. This has nothing to do with chemical additives. It is the normal reaction of sweet substances in watermelon juice that occur at low temperatures. The sweet substance in watermelon is mainly fructose, and the sweetness of fructose increases when the temperature drops. This is the characteristic of fructose. Fructose has two configurations in water, an a-configuration and a B-configuration, the latter being sweeter than the former. Low temperature will promote the transformation of the a- configuration to the B-configuration. Therefore, the iced watermelon tastes better.
The fact that ice watermelon is sweeter is not mystery, so in the summer, we eat watermelon and ice it first to add “sugar†to the watermelon.
