Citric acid corrodes cans in sprite? Expert: weak acid is harmless to human body
Zaobao news a few days ago, there was a media report that a consumer in Hangzhou turned 12 cans of sprite packed in good condition into empty cans after storing them for three months. Many people cannot help worrying that sprite will " corrode" the human body.
Yesterday, Wang yanfeng, senior manager of public affairs and communications of Coca-Cola greater China, explained to morning post reporters that the citric acid in sprite has certain weak acidity and will react with aluminum or steel cans to a certain extent. over time, it may cause small eyes that cannot be seen with the naked eye. In order to prevent this kind of situation, sprite can be coated with a layer of coating. if sprite can be transported or stored under huge external force, the inner coating will be damaged. sprite will contact the can directly, and there may be small holes. over time, the liquid will leak light.
Xie Jingli, deputy director of the department of food science and engineering of east China university of science and technology, said yesterday that it was inappropriate to use the word " corrosion" to describe food and beverage. The largest proportion of substances in sprite is neutral sugar water. the citric acid content of weak acid is very low, which is harmless to human body.
