燕窩乾塊約有50-62%的成份是蛋白質，用上2小時燉煮方式的話，約有5%的蛋白質會進入液體部份。1494Please respect copyright.ＰＥＮＡＮＡQ2WydokhmB

（圖2）白燕與血燕的顏色分別，相信是基建於Nitrite含量的不同(Ref2)。1494Please respect copyright.ＰＥＮＡＮＡ6SWykoz8AP

血燕Nitrite含量較高，因而呈現紅色。隨著Nitrite含量越低，便會相繼呈現黃色或白色。1494Please respect copyright.ＰＥＮＡＮＡnCcoUsuwxk

燕窩中能找出一隻酶素Nitrate Reductase，能夠將Nitrate轉變成為Nitrite。1494Please respect copyright.ＰＥＮＡＮＡOcVKzWPUyO
同時間，燕窩中亦存有能夠抑制那隻Nitrate Reductase的物質(Ref1)。1494Please respect copyright.ＰＥＮＡＮＡv3TkobLn6j

（圖3）燕窩中蛋白質含量最高的是一種與人類Muc-5AC蛋白質非常相似的蛋白質。1494Please respect copyright.ＰＥＮＡＮＡcqCuKUqrSs

血燕及白燕中同樣能找到，但實際功用及功效暫時尚未清楚。1494Please respect copyright.ＰＥＮＡＮＡMwXotR2bf3
