Qualitative and Quantitative Analysis of Edible Bird’s Nest Based on Peptide Markers by LC-QTOF-MS/MS

Abstract: Edible bird’s nest (EBN) is an expensive health food. There are many adulterants in the market. It remains challenging to discriminate EBN from its adulterants due to a lack of high-specificity markers. Besides, the current markers are confined to soluble fraction of EBN. Here, both soluble and insoluble fractions were analyzed by LC-QTOF-MS/MS. A total of 26 high-specificity peptides that were specific to EBN were selected as qualitative authentication markers. Among them, 10 markers can discriminate EBN from… Show more

“…This licensing system is quite complex and non-transparent, and discretion (freedom to make one's own decisions) applies to ENS imported from Indonesia [29]. Therefore, ESN exporters from Indonesia are advised to pay great attention to the issue of hygiene standards, considering that this product is very expensive because it contains high protein [30,31], which is useful for health.…”
