“…utilized Sodium Dodecyl Sulfate Polyacrylamide gel Electrophoresis (SDS‐PAGE) and AccQ•Tag method with high‐performance liquid chromatography (HPLC) for the analysis of protein profile and amino acid composition in house and cave EBN . The study provided the fingerprint profiles for the protein and amino acid compositions of the cave and house nests, which was also supported by another independent study by Seow et al . Apart from the protein and amino acids, EBN is also made up of other metabolites constituents.…”

and Reactivity (LR11ES39), Team: Medicinal Chemistry and Natural Products, Avenue of Environment, 5019 Monastir, TunisiaThis work investigated the polar (PC: protein, amino acid and metabolite) and non-polar (NPC: fatty acid) compounds and bioactivity characteristics of the EBN harvested from the state of Johor in Malaysia. The electrophoretic gels exhibited 15 protein bands (16-173 kD) with unique protein profile. Amino acids analysis by AccQ·Tag method revealed 18 types of amino acids in EBN. Metabolite profiling was performed using High-Performance Liquid Chromatography coupled with Quadrupole Time-of-Flight Mass Spectrometer (HPLC-QTOF/ MS) technique and a total of 54 compounds belonging to different groups were detected and identified. These findings help to uncover the relation of therapeutic activity of EBN. The EBN was further extracted with AcOEt and BuOH. The AcOEt extract was fractionated into three fractions (F 1 À F 3 ), and the high triglyceride content in F 2 was verified by gC-FID. The three groups of fatty acids discovered in EBN are 48.43 % of poly-unsaturated (PUFA), 25.35 % of saturated fatty acids (SFA) and 24.74 % of mono-unsaturated fat (MUFA). This is the first time to report results ofEBN, BuOH, and AcOEt extracts and of fraction F 2 (TEBN) on their analysis for their antioxidant activities by DPPH, ABTS and catalase assay and for their paraoxonase and anti-tyrosinase activities. The results showed that TEBN exhibited the significant bioactivity in all assays. These findings suggest that TEBN is a good source for natural bioactive compounds in promoting body vigor. Current work widened the content of EBN especially on the triglyceride and also marked the content of specific location (Johor, Malaysia) of EBN origin.[a] IC 50 (mg/mL): the concentration at which 50 % is inhibited.

Edible bird's nest (EBN), the swiftlet's nest, has been consumed for centuries as a tonic or health food. The information upon the usage and benefits of the EBN are largely based on historical and observational reports since its discovery, until some were proven scientifically at recent times. Studies have been conducted on the major components of the EBN, i.e. glycoprotein, in attempts to elucidate the roles of the glycoprotein in terms of functionality toward health improvement. This article presents a review of the physicochemical and nutritional composition of EBN from different harvested locations and its functional properties. The conversion of EBN glycoproteins to glycopeptides via suitable hydrolysis methods to produce bioactive EBN glycopeptides was demonstrated, and it showed improvements in the functionality and nutritional values of EBN. Some applications of EBN glycopeptides into the new development of food and beverage products showed positive results, implicated to the bioavailability of the EBN glycopeptides. The combined information in this review will benefit the scientific communities, EBN manufacturers, and nutraceutical industries.

“…Despite TPC, zinc, valine, and calcium contents being identified responsible for EBN classification based on production origin, Seow et al [51] reported glutamic acid and tyrosine as the differentiating markers between house and cave nests. This may be due to the use of the entire amino acids for analysis in Seow et al's study.…”

Authenticity of food is of great importance to ensure food safety and quality, and to protect consumer rights. A rapid and accurate method for authentication of edible bird's nest (EBN) was proposed by using nutritional profile and chemical composition, and pattern recognition analysis. The authentication of EBN includes identification and classification of EBN by production origin (houses or caves), species origin (Aerodramus fuciphagus or Aerodramus maximus) and geographical origin (Peninsular Malaysia or East Malaysia) based on their active compositional content. Three pattern recognition methods, principal component analysis (PCA), hierarchical cluster analysis (HCA) and linear discriminant analysis (LDA), were employed to develop classification models for authentication of EBN origins. Compared to PCA and HCA, LDA is more accurate and efficient in distinguishing EBN by different production, species, and geographical origins, having classification ability of 100% and prediction ability of 92% as validated by cross-validation method. The key chemical markers for production origin differentiation are total phenolic content, zinc, valine, and calcium, while for species origin discrimination are sialic acid, serine, phenylalanine and valine, and for geographical origin differentiation are arsenic and mercury. The findings suggest that nutritional and chemical profiles combined with pattern recognition analysis are promising strategy for rapid authentication of EBN and its products.
