1. By observing the length of the scales, you can determine whether the flesh content is more or less. In terms of flavor, thin-skinned meat is more delicious and more cost-effective to buy. Dragon fruits with longer scales usually have thicker skins and therefore less flesh and less flavor. Dragon fruits with shorter scales have thin skin and more flesh. The flavor is great. So when choosing, remember to pick one with short scales, the shorter the more flavorful. Thin skinned and meaty sweetness.

2. Look at the location of the root. Look at the root of dragon fruit, if the root of dragon fruit looks blackened or even moldy, this kind of dragon fruit means that it has been damaged and tastes bad. If the root of dragon fruit looks dry and intact, it means that the dragon fruit is fresh and most of them are of high quality.
