屋燕与洞燕之分别 House Nest And Cave Nest

屋燕 – 属官燕类, 指燕子在屋里所筑成的巢窝, 燕屋是模仿燕子的天然栖息地而建成, 给燕子一个理想栖居地. 但燕子并非人工喂食, 燕子早出寻找食物充饥, 而傍晚则飞回燕屋栖息.
燕屋里所筑成的燕巢含有羽绒及杂质较少, 外形较佳, 口感为软腍, 發頭約5 - 6倍, 浸燉需時较短. 由于屋燕质地较软腍, 所以燉得太久會溶於水中, 影响口感, 此属正常現象, 不是燕窝品质的問題.

洞燕 – 来自官燕, 毛燕及草燕类. 指燕子在石壁或岩洞里所筑成的巢窝, 由于巢窝暴露在石壁或岩洞种种环境因素与气候变化的原故, 不但含有羽绒及额外杂质较多, 而且含有重金属污染风险.
洞燕多呈深色, 外形不太討好, 口感为爽口, 發頭約2 - 3倍, 浸燉需時较长. 而洞燕质地较坚实, 所以燉時较不易溶於水中. 洞燕因为采集过程困难及危险性高, 所以价格售得高.

House Nest: Bird type “Swiftlet”. The house nest refers to nests that are build in farmhouses that are humid and dark. The interior temperature, brightness and relative humidity are relatively similar to the conditions found in the bird natural cave habitat. The swiftlet leaves the farmhouse to find food in the early morning and returns in the evening. Since house nest habitat conditions are better than in harsh natural caves, the nest contain less feathers and impurities, generally cleaner and have higher swelling capacity, taste smooth and mellow.

Cave Nest: Bird type “Swiftlet”, “Feather Swallow”, “Grass Swallow”. The cave nest refers to nests constructed in caves and on cliffs. Owing to the harsh natural climate and environment, the nest is firm, hard and deep in color. It is not as well shaped as the house nest and generally contains more foreign materials and feathers than house nest. Besides, cave nest are exposed to the risk of heavy metals contamination from environmental factors. Cave nest is crunchy with a low swelling capacity that lengthens the time for it to swell when preparing.
