"Children want to eat watermelon, so I bought a vendor who claimed to be a local sweet potato at the melon stall on the street. But when I cut it open, I felt bitter and sweet. I suspect that saccharin has been injected into this watermelon. I don't know if I can still eat? "

On May 17, Ms. Cai from Qinzhou District called the newspaper's convenience service hotline to reflect the "miracle" she encountered when eating melons. After putting down the phone, the reporter immediately contacted and consulted relevant people.

According to stationmaster Zhang of the Economic Workstation of Qinzhou Agricultural Bureau, according to relevant regulations, saccharin cannot be injected into watermelons. Now the watermelons sold in Tianshui melon and fruit market mostly come from the south, and only a small amount comes from Longnan City, our province. Even if the local watermelon is in the greenhouse, it hasn't blossomed yet, let alone put it on the market. Therefore, it is deceptive for individual melon vendors to claim that the melons they sell are local melons.

"That is to say, the watermelons sold in our city are basically shipped from the extreme south, not melons injected with saccharin. Because once saccharin is injected, watermelon is easy to go bad and will rot in a few days. " During the interview, stationmaster Zhang told the reporter that what Ms. Cai said "maybe the vendor injected saccharin" was just a doubt, because the vendor only injected saccharin into the watermelon, and eventually it would seep out because of the pressure inside. Generally speaking, in order to enhance the sweetness of watermelons, individual melon vendors or farmers start to inject saccharin and pigment when watermelons are not picked, which will make the effect better, and the melon taste is not only sweet but also red.

So, is the bitter and sweet watermelon injected with the hormone red accelerator (ripening agent)? Stationmaster Zhang also denied this. "If the watermelon with ripening agent is not sold within 24 hours, the skin will become soft and you will have diarrhea after eating it." Stationmaster Zhang said that because it is ripening, this kind of watermelon with white and red seeds tastes bad and is difficult to sell. Therefore, no matter farmers or vendors, ripeners are rarely used now. The watermelon bought by Ms. Cai tastes bitter. Only after testing by relevant departments can we know the specific reasons.

"But one thing is certain, if too much saccharin is injected during the watermelon growth period, the mature watermelon will have bitter taste. And it is difficult to be discovered by consumers. " In this regard, stationmaster Zhang suggested that Ms. Cai stop eating the watermelon she bought.

How to choose a good watermelon

Watermelon pulp contains more water and tastes sweet, which is a good product for people to quench their thirst in summer. But careless purchase can also lead to human poisoning. Usually, people call this kind of watermelon poisonous watermelon.

"The toxicity of poisonous watermelon comes from excessive application of hormones (ripening agents, swelling agents) and pesticides by melon farmers. After people eat this kind of watermelon, they will have poisoning symptoms such as nausea, vomiting and diarrhea. Therefore, when buying watermelons, everyone should pay attention to that all the following characteristics are poisonous watermelons, and it is best not to buy them. " Zhang said, stationmaster of the Economic Workstation of Qinzhou Agricultural Bureau: First, the yellow-green stripes on the melon skin are uneven, and the flesh is particularly bright after cutting, but the melon seeds are white and have no sweetness. The second kind is watermelon with swelling agent. This kind of watermelon is big, which can generally reach 6- 10 kg. Generally, a watermelon weighing about 4 kg is normal. The third kind is watermelon with hormone. Because of the uneven spraying and absorption of pesticides, it is easy to have crooked melons and deformed fruits, such as asymmetry at both ends, depression in the middle and swelling at the head and tail. , and the surface has spots or large color difference. Don't buy this crooked melon and deformed fruit. The shape of a normal watermelon should be spherical or oval with a smooth surface.

"When citizens and friends eat watermelon, if they find that the taste is not good, especially the feeling of numbness in the tongue, they should stop eating immediately and don't take any chances." Zhang webmaster finally reminded that.
