Hebei Zhangjiakou was exposed to "formaldehyde preservation before cabbage loading", and the specific flow direction of cabbage involved is still being traced. Consumers can quickly identify cabbage in several ways.
When smelling, do not buy if you smell a pungent odor, as formaldehyde has a pungent odor. Observing the appearance, the outer leaves of "formaldehyde cabbage" are usually bright and good-looking, and there is no wilting phenomenon. While normal cabbage is transported and compressed over a long distance, the outer leaves are inevitably deformed or hairy. Check the inner layer. If the surface is shiny but the interior has begun to rot, it can basically be determined that formaldehyde has been sprayed, because formaldehyde can only maintain the surface without rotting, but can not protect the inner layer.
After you buy it home, you should also take care when washing it: peel off the outer leaves, remove the core, and it is best to soak it for 30 minutes and then rinse it with running water. According to the relevant regulations in China, it is illegal to add formaldehyde to food. If you find similar leads, please report them to the relevant departments in a timely manner.
