Why do pineapples have "black hearts"?

The phenomenon of "black heart" was found in pineapple. The stall owner explained that the "black heart" proved that the pineapple was ripe, not only edible, but also very sweet. Subsequently, the reporter learned about other fruit shops in the city. Most shopkeepers said they had encountered "black-hearted" pineapples. A fruit shopkeeper said that in order to sell "black-hearted" pineapples, he usually explained to customers that pineapples were ripe, but he never ate those "black-hearted" pineapples.

Can "black heart" pineapple be eaten? Teacher Wang Huakun, a fruit and vegetable expert at Suzhou Agricultural Vocational and Technical College, said that generally speaking, the "black-hearted" pineapple actually suffers from rotten heart disease, and most of the cases are caused by management negligence or sudden climate change during the growth of pineapple. Many "black-hearted" pineapples are actually "black-hearted" because of improper transportation and storage. Experts suggest that rotten fruit is not edible.

Don't eat.
