How to tell whether potatoes germinate?

During storage, if potatoes are exposed to light for a long time, the surface layer will produce chlorophyll, which will germinate, and then a lot of solanine will be produced in the chlorophyll part. Green potatoes are obviously rich in chlorophyll and solanine.

Don't buy potatoes if they turn green when you buy them. If the fresh potatoes bought home are too late to turn green, the solanine content of potatoes is not high at this time. Just peel, cook at high temperature and add some vinegar, and most of the solanine will decompose.

Solanum nigrum is very dangerous for human beings. It is corrosive and irritating to human gastrointestinal mucosa. If poisoned, there will be symptoms such as nausea, vomiting, abdominal pain and diarrhea. In addition, Solanum nigrum has a strong inhibitory effect on cholinesterase activity in the central nervous system. If severely poisoned, convulsions, shock, coma and dyspnea may occur.

The results showed that different amounts of solanine could be detected in different kinds of fresh potato samples in the market, with the content ranging from 26 to 88 mg/kg (with an average of 56 mg/kg), in which the solanine content in potato meat was lower than 10mg/kg, while the solanine content in potato skin was between 90 and 400 mg/kg, so even if it was eaten every day, there would be no problem.
