Why are there no watermelons and melons in canned food?

Generally, canned fruits have a certain hardness, such as pears and pineapples, or have a skin, such as oranges, and these fruits have a remarkable feature that they are not seasonal. As a mature canned fruit, it is fragrant and soft. Hami melon is too crisp and tender, and rich in fiber. The finished product has only a crisp feeling, which is far from fresh fruit.
