当我们煮海参时，你可能会注意到水的颜色变成了绿色。这究竟是为什么呢？原来，这是由于海参体内的一种物质引起的。

海参是一种生活在海洋中的海鲜食材，它的体内含有一种被称为硷基性多糖的物质。当我们将海参放入热水中煮沸时，其中的硷基性多糖会释放出来，并与水分子结合形成一种化合物。这种化合物的颜色正好是绿色的，所以煮海参的水就呈现出了绿色。

虽然煮海参时水呈现出绿色，但是并不代表水污染或不安全。实际上，这种绿色其实是一种天然的反应，是由于海参体内的物质与热水相互作用所致。我们可以放心地继续煮海参，而不必为水的颜色担心。

When we cook sea cucumber, you may notice that the water turns green. Why does this happen? It is actually due to a substance inside the sea cucumber.

Sea cucumber is a seafood ingredient found in the ocean, and it contains a substance called alkaline polysaccharides. When we boil sea cucumber in hot water, the alkaline polysaccharides are released and combine with water molecules to form a compound. The color of this compound happens to be green, hence the green color of the water when cooking sea cucumber.

Although the water turns green when cooking sea cucumber, it does not indicate pollution or unsafe water. In fact, this green color is a natural reaction caused by the interaction between the substances inside the sea cucumber and hot water. We can continue to cook sea cucumber without worrying about the color of the water.
