Matters needing attention in purchasing pitaya

Looking at the external color, the fresh pitaya is red and green. Fresh and mature pitaya is generally red in color, looks very red, scales are green, looks very green, and looks very bright as a whole, because mature pitaya will absorb enough nutrients and sunlight when growing, so it will be as red as fire. The bright pitaya is fresh and ripe, so it tastes good and tastes sweet and juicy.

The fresher the pitaya, the better. If you want to see whether it is fresh or not, you can also see the root of pitaya in addition to the color. If the roots seem to have signs of blackening or even mildew, such pitaya is not cheap, which means it is broken and can't taste good.
