Preliminary study on free sialic acid content of edible bird nest from Johor and Kelantan

2014

Edible bird's nest (EBN)is made from the saliva of swiftlet from the Aerodramus species. It is one of the most widely consumed traditional health food by the Chinese community due to its claimed medicinal value. EBN contains glycoproteins with abundance of sialic acid (SA). EBN with higher SA content has a potential to command for higher price. The objective of this study was to determine and compare free SA content of EBN collected from Johor and Kelantan. A total of 23 and 30 of raw and unprocessed EBN samples were obtained from Kelantan and Johor, respectively. SA from EBN samples were analysed using LC-MS/MS. Johor showed higher content of free SA with the value of 135.04 ± 29.60 mg/kg compared to Kelantan which has a value of 95.55 ± 25.6 mg/kg. Highest content of free SA was found in EBN from Pontian district, Johor.
