10 morning, citizens Mr. Gao called the newspaper news 110 hotline 82061110. He bought a cold seaweed in the Kuang Shan farmer's market. Home and steamed bread were steamed in the pot, and the steamed bread was dyed green. He doubted to buy a dyed kelp. In this regard, some experts say kelp color too green may be soaked in copper chloride solution.
10 morning, when the reporter saw Mr. Gao, he brought the cold kelp and steamed bread belt that he bought the day before. The reporter saw that in this cold seaweed, there are not only kelp silk and bean curd skin, but also a piece of steamed bread leather in the middle. The silk of the kelp looks very green. There are several bright green spots on the skin of the steamed bread, and some of the bean curd skin has been dyed into the light green.
Mr. Gao told reporters that on the afternoon of 9, he bought this cold seaweed from the farmer's market in Kuang mountain. In order to eat more safely, he poured the dish into the plate to steamed and put a steamed bread on the kelp. "After opening the pot, I didn't care about it at the beginning. I suddenly found that there were green spots on the steamed bread, and then a lot of bean curd skin had been dyed green." Mr. Gao said.
10, the afternoon, the reporter came to the city of a few vegetables market, in two stalls selling kelp, found that the wet kelp silk basically bubble in the basin, showing a dark green, and large dry kelp is black brown.
food experts said that kelp contains copper ions, so its color is green, but because of less content, kelp is greener. Under normal conditions, the color of fresh kelp is uneven because the thickness of the kelp is different, that is, the thickness of the kelp is large and the green is deeper; the thickness of the kelp is small, the green is shallow, and even yellow. "If kelp is emerald green, it should be related to the increase of copper ion content, and it is not ruled out that it can be soaked in copper chloride solution." The expert said that after the "chemical beauty" kelp, long-term consumption of the body is very harmful, so the public should pay careful attention when buying.
