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。1128Please respect copyright.PENANAOidX442glZ

(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)。1128Please respect copyright.PENANAHnScO4zEjh

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。1128Please respect copyright.PENANAV0h5DeTjVx

燕窩中能找出一隻酶素Nitrate Reductase,能夠將Nitrate轉變成為Nitrite。1128Please respect copyright.PENANAR4fNxHj7n7
同時間,燕窩中亦存有能夠抑制那隻Nitrate Reductase的物質(Ref1)。1128Please respect copyright.PENANAxnrnlfgdYv

(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。1128Please respect copyright.PENANA6gifLxHxec

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。1128Please respect copyright.PENANAHiOA2EmQdO
