summer is coming. It can’t be more comfortable to go home and eat an iced watermelon after a hot day. The research shows that it is stored at 21 ℃ & mdash& mdash; Watermelon equivalent to room temperature has more nutrients. Compared with newly picked watermelon, the lycopene of watermelon stored at 21 ℃ is 40% more, which can be transformed into & beta of vitamin A- Carotene is 50% ~ 139% more.
scientific research shows that watermelons preserved at room temperature contain more nutrients than newly picked watermelons, especially lycopene.
lycopene is a very healthy antioxidant that helps prevent heart disease and some cancers. The researchers tested several popular watermelons, which were stored at 21 ℃, 13 ℃ and 5 ℃ for 14 days.

and freezing watermelon in the refrigerator or freezer slows down the process of continuing to produce nutrients.
iced watermelon tastes delicious, but its nutrients are much less than those preserved at room temperature.
refrigerated watermelon is also easy to deteriorate. The storage period of watermelon at 13 ℃ is 14 ~ 21 days. When they are stored in refrigerator or freezer, that is, when they are stored at 5 ℃, the watermelon begins to deteriorate after one week.
