Although it has just arrived in spring, many anti season fruits have appeared on the market.

A fruit trader who has been involved in fruit business for many years told reporters that many anti season fruits were ripened and kept fresh with some chemicals. During this process, some anti season fruit became "problem fruit".

Strawberry: strawberry with hollow, irregular shape and large size is usually caused by excessive hormone.

Strawberries grow shorter with ripener or other hormone drugs, and the color is fresh, but the fruit flavors fade.

Banana: in order to make the banana skin bright yellow, some illegal peddlers use sulfur dioxide to ripening, but the pulp is still hard and not sweet at all.

Sulphur dioxide is harmful to the human body.

Watermelon: use ripener, expanding agent and highly toxic pesticide to make the watermelon poison.

The stripes of this watermelon skin are uneven. After cutting, the melon flesh is especially bright, but the melon seeds are white, and have peculiar smell after eating.

Grapes: some illegal traders and fruit growers use ripener ethephon.

Users dilute ethylene with water and dilute the green grapes into the diluent. After one or two days, the grapes become purple grapes.

If possible, it is best to buy less seasonal fruits, so you should buy more seasonal fruits.

Seasonal fruits are ripe in natural environment, without ripener, and do not need too many preservatives when they are stored.
