Peptide markers for authentication of edible bird's nest and related products

Overview

HKBU has developed a novel method for authenticating edible bird's nest (EBN) and related products using specific peptide markers derived from EBN hydrolysates.

Problem addressed

This method leverages mass spectrometry techniques to identify markers that can distinguish between authentic EBN, white EBN, grass EBN, and adulterants. It help consumers to identify authentic EBN from the market.

Innovation
  • Peptide markers are selected based on their retention time, mass-to-charge ratio (m/z), specificity, and stability across multiple batches.
  • Identifying based on the whether the hydrolysate comprises the one or more peptide markers if the sample comprises the EBN
Key impact
  • This method does not require complex pretreatment steps like deglycosylation or reduction, making it simpler and faster. 
  • The method is practical for commercial application and offers high sensitivity and specificity.
Award
  • Silver Medal at the “2024 Geneva International Exhibition of Inventions”
Application
  • Authentication of EBN white EBN, grass EBN in raw material and related products .
