【英语时差8,16】菠萝-“水果之王”（下）（在线收听）

Pineapple juice works as a skin conditioner because the bromelain breaks down dead and damaged outer layers of skin, exposing the softer skin underneath. Putting pineapple juice on an open wound might be painful but it can also break down damaged tissue and kill bacteria. But one place fresh pineapple does not work is in jelled salads because gelatin is a form of protein, and sois broken down by bromelain, leaving you a very sloppy salad. But don’t despair; since bromelain is broken down by heat, you can still make a jello mold with cooked or canned pineapple — only you won’t be able to use the cooked pineapple to tenderize meat, soft your skin.
