When potatoes germinate, they produce a substance called solanine, which mainly exists in the stems and leaves of potatoes to protect themselves.
Under normal circumstances, potatoes also contain "solanine", but the content is relatively low, but once they germinate and turn green, they will produce a lot of solanine, which is beyond the scope of safe consumption.
At this time, if you eat sprouted potatoes, it is easy to be poisoned.
However, if the whole potato is thrown away because of a little "bud", is it too wasteful? But what should you do if you throw it away?
Whether it can be killed by high temperature methods such as "boiling and frying". But in general, many families will choose to cut off the buds when making potatoes.
