Tips for picking oranges:

Generally speaking, mature oranges have bright colors and smooth surfaces, and there are no obvious depressions or bulges. If the orange is too dark or has obvious spots on its surface, it may be immature or of poor quality. So when buying oranges, choose oranges with bright colors and smooth surfaces. Oranges of the same size have heavier weight, full flesh, sufficient water and better taste.

Orange peel is also an aspect that should be paid attention to when selecting. Generally speaking, high-quality orange peel is delicate, elastic and has no obvious defects on the surface. If the orange peel is rough, inelastic or has obvious defects on the surface, it may be of poor quality or stored for too long. Therefore, when buying oranges, choose oranges with delicate skin and flawless surface.
