In today's advanced society, it can be said that we don't have to worry about the season for the fruits we want to eat; we can get them whenever we crave them. All kinds of delicious fruits can be enjoyed almost year-round. However, health experts advise that it's best to eat fewer out-of-season fruits. Grapes:
Some unscrupulous vendors and growers use ripening agents—ethephon. Users dilute ethephon with water, soak immature green grapes in the solution, and within a day or two, the green grapes turn purple. Bananas:
To make banana skins tender and yellow, some unscrupulous vendors use sulfur dioxide to ripen them, but the flesh remains hard and not sweet at all. Sulfur dioxide is harmful to the human body. Watermelons:
The excessive use of ripening agents, expanders, and highly toxic pesticides can make watermelons toxic. Such watermelons have uneven stripes on their rind, the flesh inside is exceptionally vibrant after being cut, but the seeds are white, and there is an aftertaste in the mouth after eating. Strawberries:
Large, irregularly shaped strawberries with hollow centers are generally caused by an excessive amount of hormones. After using ripening agents or other hormone-based drugs, the strawberries have a shorter growth period and a fresher color, but their flavor becomes bland.
