1. Can yam be eaten after germination?
Yam germination is non-toxic and will not affect eating. However, the germination of yam shows that life has begun to grow. Germination will lead to the decline of nutrients in yam, slight germination will lead to little loss of nutrients, while more serious germination will lead to a lot of loss. If the yam sprouts, you can remove the buds before eating. But the best way is to pay attention to preservation and avoid the occurrence of yam germination. In order to avoid yam germination, it can be stored in the refrigerator, so it is not easy to germinate. However, if the storage temperature is too low, yam is easy to rot, so the optimal storage temperature is between 5℃ and 10℃. If the yam turns black, you must not eat it.
