1、燕(yan)窩(wo)(wo)發頭(tou)(tou):燕(yan)窩(wo)(wo)在浸透后,與(yu)干身時(shi)的(de)差異倍數越大,即“發頭(tou)(tou)”越好,優質燕(yan)窩(wo)(wo)的(de)“發頭(tou)(tou)”可(ke)達6倍以上。
2、燕窩口感:優質燕窩口感大多是細膩爽(shuang)滑,富有(you)彈性(xing);如(ru)(ru)果(guo)燉燕窩的水如(ru)(ru)有(you)粘性(xing),可能是涂過(guo)膠或(huo)加過(guo)增稠劑,這種就不要再購買食用了。
3、燕(yan)窩(wo)含(han)水(shui)率(lv):優(you)質燕(yan)窩(wo)手摸(mo)應有干爽的感覺(jue),一些較濕(shi)的燕(yan)窩(wo)水(shui)份較多,存放不(bu)當容易發霉(mei)。
4、燕(yan)(yan)窩(wo)產地:主要(yao)產地有(you)印(yin)尼、馬拉西(xi)亞(ya)(ya)、泰國(guo)以及我國(guo)南(nan)海諸島,其(qi)中(zhong)印(yin)尼燕(yan)(yan)窩(wo)品質較(jiao)佳,印(yin)尼燕(yan)(yan)窩(wo)產量較(jiao)大;在燕(yan)(yan)窩(wo)加工工藝及其(qi)價格上,馬來西(xi)亞(ya)(ya)的燕(yan)(yan)窩(wo)更占優勢,即食燕(yan)(yan)窩(wo)很多人會(hui)選購(gou)馬來西(xi)亞(ya)(ya)燕(yan)(yan)窩(wo)。
5、燕(yan)(yan)(yan)窩(wo)(wo)種類(lei):燕(yan)(yan)(yan)窩(wo)(wo)可(ke)分(fen)為白(bai)燕(yan)(yan)(yan)、血(xue)燕(yan)(yan)(yan)以及(ji)黃燕(yan)(yan)(yan)等(deng),其(qi)中白(bai)燕(yan)(yan)(yan)燕(yan)(yan)(yan)窩(wo)(wo)質地潔(jie)白(bai)、質量(liang)較佳,大多人選購(gou)這(zhe)類(lei)燕(yan)(yan)(yan)窩(wo)(wo)用(yong)于送(song)領導或(huo)客戶(hu);血(xue)燕(yan)(yan)(yan)燕(yan)(yan)(yan)窩(wo)(wo)其(qi)礦物質含(han)量(liang)豐(feng)富(fu),營養價值高于白(bai)燕(yan)(yan)(yan)燕(yan)(yan)(yan)窩(wo)(wo)。
