Abstract
Edible bird’s nest (EBN) is rich in nutrients and health benefits; making it one of
the Chinese delicacies over the centuries. However, due to the overpriced and limited supply
of EBN, it is being adulterated with other cheaper versions. Therefore, the aim of this study
is to establish a method of detecting adulterants in EBN using Fourier transform infrared
spectroscopy (FTIR) as the spectrum fingerprinting analysis together with principal
component analysis (PCA). Spiked samples have been developed for Tremella fungus and
porcine gelatine at the concentrations of 1%, 5%, 10%, 20% and 30% (w/w). The FTIR
method combined with PCA analysis was able to detect the adulteration of porcine gelatine
and Tremella fungus in the sample of adulterated EBNs at low concentration of 1% (w/w).
The simple approach employing FTIR combined with PCA may provide a useful tool for
EBN detection.
