Solanine is a glycoside compound, which widely exists in solanaceae plants, such as tomatoes, peppers, eggplant and potatoes. Although Solanum nigrum is a natural compound, don't eat it. Solanum nigrum content varies in different foods. In potatoes, solanine mainly exists on the surface of buds and skins of new potatoes, while the content in mature potatoes is relatively low.
Potatoes stored for a long time are easy to germinate, and the content of solanine in buds will also increase. Solanum nigrum is a toxic substance, and it should be eaten in moderation when eating foods containing solanum nigrum. For potatoes that germinate easily, it is best to remove the buds and green parts on the surface before cooking. For other vegetables with solanine, we should also pay attention to whether they are fresh and correct cooking methods to reduce intake.
Common vegetables that produce toxins:
1. Eggplant:
Eggplant contains solanine, which is a glycoside compound, so be careful to eat it.
2. Spinach:
When spinach is stimulated or stored for a long time, it will produce certain oxalate and nitrate, which is not easy to eat.
3. Pumpkin:
Pumpkin contains an ingredient called mannitol. In addition, the skin and pulp of pumpkin also contain citrulline and carotene. Don't eat too much.
4. Adenophora adenophora:
Adenophora adenophora is a kind of Chinese herbal medicine, but it contains saponin, so it should be eaten carefully.
5. Taro:
Taro contains a lot of oxalic acid, especially in its central part.
6. Celery:
Celery contains volatile oil, which is difficult to be ingested in large quantities for a long time.
7. Mushrooms:
Some mushrooms contain toxic substances, such as Coprinus comatus, russula, poisonous amanita, etc. Therefore, if you don't know the toxicity of a certain mushroom, you'd better not pick and eat it at will.
8. tomatoes:
The toxic solanine in tomato leaves is inedible, and the solanine content in tomato will also increase during the ripening process, which is not easy to eat.
