The first thing to do when choosing a grapefruit is to master the general principle of "tumbler", the upper tip and lower width are the standard type of grapefruit, of which it is better to choose a flat round and short neck (the bottom is better). This is because the grapefruit with a long neck has fewer sacs and appears more skiny.
2. You can also select high-quality grapefruit from the aspects of eye view, specific gravity, and feel. If the skin of the grapefruit is fine and clean, the surface oil cells are translucent, and the color is pale yellow or orange yellow, it indicates that the grapefruit has a high maturity and is juicy and sweet. For grapefruit of the same size, choose a heavy portion. When pressing hard, it is not easy to press, indicating that the sac is tight and of good quality. Note that if the individual is large and the portion is light, the skin is thick and the meat is less, and the taste is not good.
