当然不能吃了，我在食品公司工作过，处理过土豆。的确如有两位朋友说的那样：龙葵素作者: discovery 时间: 2003-3-22 08:54
The potato is part of the nightshade family and as such does have some disagreeable traits. One should never eat anything green from a potato. The leaves and stem are poisonous.
The greenish hue is actually chlorophyll, but it is also an indicator that an alkaloid, called solanine, may be present under the skin of the potato. Solanine develops in potatoes when they are stored in the presence of light (which also encourages chlorophyll formation) and either at very cold or quite warm temperatures. It is toxic, however it would take a very large number of green potatoes to make you ill. Since solanine collects just under the skin, it is safe to peel away the skin and a thin layer of white flesh before you cook the potato. And you're right about the sprouts: They too can be toxic and shouldn't be eaten, though it would take many sprouts to make you ill.
When confronted by green skin on a potato, simply peel it away. Keep as much of the rest of the skin as possible.
It's best to check potatoes for any green coloring before you buy them. Then, store them at cool room temperature in a dark, dry place.作者: big_hard 时间: 2003-3-23 22:44
用小刀去掉芽眼及周围的部分就行了，没有什么害怕的。以下是摘自相关专业网站：“一般地说，土豆发芽后就不要吃了，这是因为土豆中含有龙葵素，这是一种对人体有害的生物碱。平时土豆中龙葵素含量极微，一旦土豆发芽，芽眼、芽根变绿，溃烂地方龙葵素的含量会急剧升高，若食之，可产生恶心、呕吐、腹痛、腹泻，重者则导致呼吸困难、昏迷。若发芽不严重，可将芽眼招干净，并削去发绿部分，再放在冷水中浸泡一小时，有毒的龙葵素便溶解在水中；烹调时，再加点醋，烧熟烩烂即可去掉毒素”
