Most pomelos will have varying degrees of dry water in the later stage of storage. Dry water is a common physiological disease of citrus fruits in the late ripening and postharvest storage period, and there are two main forms: crumpled dry water and granulated dry water.
Although the grapefruit is cut off from the supply of inorganic matter and water, it is still a living body, still maintaining breathing and metabolism. Generally, after two weeks of indoor storage, the taste will become sweeter and sweeter when the water in the grapefruit gradually evaporates.
However, with the extension of the storage period, due to respiratory metabolism, nutrients are consumed during storage, the total acid content of sugar decreases, and the content of vitamin C also shows a downward trend. The peel of grapefruit will lose water, and the fruit will appear irregularly expanded, dehydrated and hard, dry, lightened in color, the juice rate of the pulp decreases, and the taste is dry and tasteless, becoming the "hard core" that everyone sees.
So, how do you choose delicious grapefruit?
How to pick grapefruit
Remember the five-character rule of picking grapefruit: big, sharp, yellow, hard, heavy
Look at the shape
Grapefruit should try to choose a large one, generally a large one will ripen better. Choose one with a pointed head, short neck, and a wide and flat underneath; The peel of the fruit that is round and rolls all over the body or has a large and long head is generally thicker.
Look at the color
Grapefruit should choose a relatively uniform skin color, and green grapefruit is generally not very mature. But don't choose grapefruit that is too yellow in color, which will be too ripe and lead to loss of moisture and affect the taste.
Touch it
The skin of ripe grapefruit is smoother and delicate to the touch, but it feels rougher to the touch.
You can also press the grapefruit with your hand, if the skin is easy to press but you can feel the hard flesh, indicating that the skin is thin and the flesh is full; If it is pressed very soft or very hard, it means that the skin is thick or not fresh.

Peeled grapefruit
The peeled grapefruit can be put into a plastic bag, sealed and placed in the refrigerator (or wrapped with plastic wrap), which can effectively ensure that the moisture is not lost and the effect of freshness is achieved. But pay attention to the fact that it is sealed and then put in the refrigerator, otherwise grapefruit is afraid of water, and directly putting it in the refrigerator will only accelerate rot.
