Yam can't be eaten after sprouting. Although yam did not produce toxic substances such as solanine after germination, the nutrients of yam itself have begun to transform in the process of yam germination. Yam germination will lead to the decline or reduction of its own nutrients, but if it is only slight germination, the loss of nutrients will be less.
Expand knowledge:
However, during germination, nutrients may also change, causing adverse effects on the human body. Therefore, generally speaking, try not to eat the germinated yam. If you have to eat it, you should deeply remove the germinated part before eating it.
Save method:
Store in a cool and ventilated place away from light: because yam is dense and strong, it is stored in a ventilated place at room temperature. Generally, it can be stored for 3-4 months in autumn and winter. In summer, it's hot. It's best to eat it within two months to prevent germination or deterioration. Do not use plastic bags to store yams during storage, which will be airtight and make yams easier to germinate. You can wrap yams with napkins and store them in a ventilated and cool place.
