Real Or Fake, Good Or Bad
A natural bird’s nest is the real bird’s nest. Illegal merchants may coat a layer of egg white or jelly on poor quality imitations. This increases the weight. The fake bird’s nest will reflect light and look opaque.
In contrast, light will penetrate through a real bird’s nest. Some fraudulent bird’s nests are made of “Malaysia rubber” or “pig skin”. The former smells and tastes acidic and does not contain nest threads while the latter releases oil after soaking in water.
As for the quality, generally speaking, the price is a fair guideline in reflecting the quality of the bird’s nest. The higher the quality and category of a bird’s nests, the greater the nutritional value, swelling capacity and beauty and vice versa.
