Abstract

Aim: Edible bird's nests (EBNs), a delicacy made from bird nests of Collocalia spp. swiftlets, are well known for also having health benefits. Washing processes for EBNs with water after harvesting the nests dissolve potential bioactives such as glycoproteins and reduce the potential health benefits of EBNs. Materials and Methods: One alternative washing method is use keratinase enzymes, but the impact on the glycoprotein profile of EBNs remains unknown. Results: This research attempted to analyze glycoprotein profiles before and after washing with keratinase. Fourier transform infrared and nucleic molecular resonance were used to observe these profiles. The results showed that there is no change between the glycoprotein profiles of EBN before and after washing with keratinase. Conclusion: Thus, keratinase washing is effective in maintaining the profiles of glycoproteins in EBNs.
