For over 1000 years, edible bird's nest has been enjoyed as a delicacy in China. Made from a swiftlet nest, a bird species native to Southeast Asia, authentic bird's nests are a superfood packed with health benefits. Edible bird's nests are primarily made into soup or drink with a variety of tasty flavors. The shape and appearance of an authentic bird's nest will come in the shape of a cup, triangle, strip, or cake depending on the quality (cup being the highest grade). When soaked in water authentic bird's nests will gradually lose their shape along with the appearance of more pronounced nest fiber. Authentic bird's nest that the color that appears after soaking. Color the water left over from the real edible bird's nest will be clear. The nest itself will also maintain its color. Texture under closed inspection, an authentic bird's nest will have uneven structure. Transparency authentic bird's nest will appear semi-transparent compared to a fake bird's nest. 

1000多年来，食用燕窝在中国一直作为美味佳肴而享有盛誉。正宗的燕窝由原产于东南亚的金丝燕巢制成，是一种对健康有益的超级食品。食用燕窝主要制成汤或饮料，具有多种口味。正宗燕窝的形状和外观根据质量的不同，呈杯状、三角形、条状或饼状（杯状为最高等级）。真正的燕窝在水中浸泡后会逐渐变形，同时出现更明显的燕窝纤维。正宗的燕窝，浸泡后呈现出的颜色。上色 真正的燕窝剩下的水会很清澈。巢本身也会保持其颜色。细细观察质地，正宗的燕窝结构不均匀。透明 真燕窝与假燕窝相比会呈现半透明状。

A bird's nest is usually white. It also exists a red version called 'blood nest'. The red bird's nest contains tyrosine that combines with that reactive nitrogen species to form a new molecule called nitrite and nitrate from the process which explains why the red bird's nest contains a high concentration of nitrite and nitrate. secondly, is a golden/yellowish color suited for replenishment after surgery. It's beneficial in a form of collagen-rich beauty DNA, it activates cell regeneration, and restores skin firmness, structure, and youthfulness. Lastly, Goldkey bird's nest is white- suited for everyone, and suited for unisex and races. Our grade bird's nest has a cup shape and even a 'strand' of saliva and contains minimal natural impurities such as dirt and feather. 

 燕窝通常是白色的。它还存在一个名为“血巢”的红色版本。红色燕窝含有酪氨酸，它与活性氮结合形成一种新分子，称为亚硝酸盐和硝酸盐，这个过程解释了为什么红色燕窝含有高浓度的亚硝酸盐和硝酸盐。其次，是适合术后补水的金黄色。它以富含胶原蛋白的美容 DNA 形式有益，可激活细胞再生，恢复皮肤紧致度、结构和年轻度。最后，金钥匙燕窝是白色的——适合所有人，男女皆宜，适合不同种族。我们等级的燕窝呈杯状，甚至有“一缕”唾液，含有极少的天然杂质，如灰尘和羽毛。

HOW TO DIFFERENCE BETWEEN A FAKE BIRD'S NEST AND A REAL BIRD'S NEST?

如何区分假燕窝和真燕窝？

In comparison, a fake bird's nest will have a relatively uniform, bumpy surface with a slight, medicinal smell. However, a fake bird's nest will show signs of discoloration due to the artificial coloring. One of the more highly prized edible bird nest varieties is the blood bird nest, a color that has been falsely attributed to the result of blood being in swiftlet saliva. For this special bird nest pay attention to the color after the soaking process. An authentic blood bird nest should still be vibrantly red whereas the fake version will stain the water. Texture, by comparison, a fake bird's nest will have neater and more coarsely distributed nest fibers. The fake bird's nest, will either be nontransparent or even reflective in some cases. This reflective quality of a fake edible bird's nest is the result of undesirable chemicals. 

相比之下，假燕窝的表面比较均匀，凹凸不平，带有淡淡的药味。然而，假燕窝会因人工色素而出现变色迹象。一种更受推崇的食用燕窝品种是血燕窝，这种颜色被错误地归因于金丝燕唾液中的血液。对于这种特殊的燕窝，请注意浸泡过程后的颜色。正宗的血燕窝应该还是鲜红的，而假的血燕窝会把水弄脏。质地，相比之下，假燕窝的燕窝纤维会更整齐，分布更粗。假燕窝在某些情况下要么不透明，要么反光。假燕窝的这种反射质量是不良化学物质的结果。

HOW TO TEST FOR A FAKE BIRD'S NEST

如何检测假燕窝

1) THE CRUMBLE TEST. A simple way to test the authenticity of your edible bird nest is to crumble it between your fingers. A natural bird's nest should break down into a powder-like substance during this process. In comparison, while a synthetic bird's nest will emulate the fragility of an authentic bird's nest, there is one key difference-fake an edible bird's nest will break off into chunks instead of a powder. 

1）崩溃测试。测试可食用燕窝真伪的一个简单方法是用手指将其捏碎。在此过程中，天然燕窝应分解成粉末状物质。相比之下，虽然合成燕窝会模仿真燕窝的脆弱性，但有一个关键区别——假燕窝会碎成块而不是粉末。

2) THE SOAK TEST. First, pay attention to the shape of the bird's nest before soaking. The fibers of the nest will also still be visible, but not nearly as uniform as when dry. On the other hand, a fake bird nest will maintain a uniform shape during the soaking process as well as a minor chemical or fatty/fried smell. The surface of the fake bird nest will also be bumpy. Next the size of the bird's nest post-soak. The fake nest doesn't expand. However, an authentic bird's nest will often double in size after soaking. Finally, should mix well with the soaking water. For instance, if you were to stir the bird's nest while soaking, a bubbly foam would appear on the surface of the water. However, since fake bird nests are made from chemicals, stirring a fake bird's nest in the soaking water will only cloud the water.  

2) 浸泡测试。首先，泡燕窝前要注意燕窝的形状。巢的纤维仍然可见，但不像干燥时那么均匀。另一方面，假燕窝在浸泡过程中会保持统一的形状，并带有轻微的化学或脂肪/油炸气味。假燕窝的表面也会凹凸不平。接下来是燕窝浸泡后的大小。假巢不会膨胀。然而，真正的燕窝在浸泡后通常会变大一倍。最后，应与浸泡水混合均匀。例如，如果你在浸泡燕窝时搅动燕窝，水面上会出现泡沫状的泡沫。然而，由于假燕窝是用化学物质制成的，因此在浸泡的水中搅拌假燕窝只会使水浑浊。
