I just baked the purple sweet potatoes and it was a little soft on one end with blakish dots in the middle of the potato around the soft bad end. So I baked the potatoes with egg whites to give it some crisp but what i found was the egg whites binded to something in the sweet potatos that had a green color and I ended up with some weird dark green liquid that binded to the egg whites. I know egg whites bind to biotin when raw so i'm thinking what the heck did it bind to when cooked? What was that green stuff in other words? was it toxic? i know the color green in potatoes is highly toxic and i know potatos originally were highly toxic. Would appreciate some feedback

When I boil purple sweet potatoes, often the water is a greenish color. It's just the anthocyanins.
