Authenticity of Edible Bird's Nest

Authenticity of Edible Bird's Nest

In recent years, there has been increasing reports of fake edible bird’s nests.  Starting in the 1990s, the first comprehensive report on authentication of edible bird's nests were published.  These reports demonstrated the possibility to use scanning electron microscopy, energy dispersive X-ray microanalysis, flame atomic emission spectroscopy, inductively coupled plasma-atomic emission spectroscopy, ultraviolet-visible spectroscopy and other physico-chemical techniques to determine the authenticity of edible bird's nest. These tests were difficult to run, expensive and only worked on some of the substances used to imitate birds nests. Recently, a China based research team developed a simple but accurate and reliable spectrophotometry method to determine edible bird's nest content. The method is based on the reaction between N-acetylneuramic acid and ninhydrin in acid solution. The method evaluates the internal content of N-acetylneuramic acid, a nine-carbon sugars, which is one of the major components in edible bird's nest.
