Chinese idioms have a cloud of "hot potato", but "hot mango" have you ever heard of it?　　Mr. Yan, who lives in Panyu, recently encountered such a "bizarre" thing. Mr. Yan said that not long ago he went to Panyu Luo XI New Town Guangzhou Country Garden next to a "walking ghost" stall to buy mango, "See the mango is small size of the ' small Taiwan Farmers ' variety, Tongmin golden, quite tempting, can't help but want to take a few eat."

Expert: Quicklime as industrial use mango or will residue heavy metals Fu Liang, director of Food Science and Technology Research Center at Jinan University, said"From a purely safe point of view, it is not poisonous to use quicklime to cover cooked mangoes," he said.

Industrial lime is cheap, but contains different grades of heavy metals, which may be attached to or even penetrated into fruit. Quicklime produces a lot of calcium ions, is partial alkaline, although there is no proof that more calcium is the direct cause of stone, but eat more, will undoubtedly increase the risk of stone.　　Dong Jin Lion said. "In order to reduce risk, consumers should use warm water before eating mango for a while, and then the calcium carbonate completely removed, and then peeled the skin to eat."　　Dong Jin Lion said.　　Business revealed the common ripening process: 1.

After 30 hours of transportation, to Jiangnan fruit and vegetable wholesale market, has been green and yellow phase. 4. In a day or two, the mango turns golden.
