“…However, EBN coP also contained N-acetylneuraminic acid, which was about half that of EBN clean , indicating that the co-products that were usually discarded also contained considerable high amounts of N-acetylneuraminic acid. The N-acetylneuraminic acid was reported to be about 72-136 g kg −1 in EBN by Quek et al, 23 signifying that the EBN under study has high N-acetylneuraminic acid content.…”

“…However, the hue values of the sample were from 83.89°± 0.19°to 89.44°± 0.56°, implying that the samples appeared to be a warmer yellow colour according to the colour wheel indication of hue angle (H°). Similarly, Quek et al 23 reported that the hue angle of EBN samples collected from Malaysia was 77.05°to 87.79°, which implied that EBN could be characterized to be pale to deep yellowish. The hue value for both EBN clean and EBNh clean was significantly higher (P ≤ 0.05) than that of EBN coP.…”

BACKGROUND Processing of edible bird's nest (EBN) requires extensive washing to remove impurities and produces huge amounts of EBN co‐products, which contain mainly feathers with glycoproteins attached, which are usually discarded. This study was conducted to recover the valuable EBN glycoproteins from the waste material. Enzymatic hydrolysis was applied to recover EBN glycopeptides from EBN co‐products (EBNcoP) and processed cleaned EBN (EBNclean) was used as control, which were then freeze‐dried into EBN hydrolysates (EBNhcoP and EBNhclean, respectively). RESULTS The recovery yield for EBNhclean and EBNhcoP were 89.09 ± 0.01% and 47.64 ± 0.26%, respectively, indicating nearly 50% of glycopeptide can be recovered from the waste material. Meanwhile, N‐acetylneuraminic acid, a major acid sugar in EBN glycoproteins, of EBNhcoP increased by 229% from 58.6 ± 3.9 to 192.9 ± 3.1 g kg−1, indicating the enzymatic hydrolysis removed impurities and thus enhanced the N‐acetylneuraminic acid content. Total soluble protein was more than 330 g kg−1 for all the samples. Colour parameter showed that hydrolysate samples have greater L* (lightness) values. Chroma result indicates the intensity of all the samples were low (< 11). Fourier‐transform infrared (FTIR) spectrum displayed that the EBNhcoP exhibited similar functional groups with EBNhclean, indicating that the EBNcoP has similar functionality as EBNclean. Significantly higher (P ≤ 0.05) 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) activities were reported in EBNhcoP after the enzymatic reaction. CONCLUSION EBNhcoP were successfully recovered from low value EBNcoP with enhanced antioxidant activities. The findings of this work are beneficial for the EBN industry to reduce wastage and enhance economic values of EBN co‐products, both economically and nutritionally. © 2020 Society of Chemical Industry

“…et al, 2020). Recent studies have found that EBN can potentiate mitogenic responses, increase the lifespan, protect neurons, promote bone mineralization, increase bone density, inhibit influenza virus, enhance the antioxidant capacity, alleviate inflammation, promote B cell proliferation and activation and reduce intestinal immune injury (Roh et al, 2012;Yew et al, 2014;Hu et al, 2016;Zhao et al, 2016;Quek et al, 2018;Hou et al, 2019). Moreover, EBN restores the immune system in the context of infection by influencing viruses through regulation of pro-inflammatory cytokines, such as IL-6 and TNF-α, and cytokines with regulatory properties, such as IL-10 and CCL2, which are also involved in the progression of UC (Haghani et al, 2016;Lee et al, 2018).…”

Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) with a complex aetiology that commonly recurs. Most drugs for UC treatment interfere with metabolism and immune responses, often causing some serious adverse reactions. Therefore, the development of alternative treatments, including nutritional supplements and probiotics, have been one of the main areas of current research due to fewer side effect. As both a Chinese medicine and a food, edible bird’s nest (EBN) has high nutritional value. Modern pharmacological studies have shown that it has anti-inflammatory, immunoregulatory, antiviral and neuroprotective effects. In this study, UC was induced with dextran sulfate sodium (DSS) to investigate the protective effect of EBN on colitis mice and the related mechanism. The body weight, faecal morphology and faecal occult blood results of mice were recorded every day from the beginning of the modelling period. After the end of the experiment, the length of the colon was measured, and the colon was collected for histopathological detection, inflammatory factor detection and immunohistochemical detection. Mouse spleens were dissected for flow cytometry. The results showed that in mice with colitis, EBN improved symptoms of colitis, reduced colonic injury, and inhibited the increases in the levels of the pro-inflammatory cytokines IL-1β and TNF-α. The T helper 17 (Th17)/regulatory T (Treg) cell balance was restored by decreasing the expression of IL-17A and IL-6 in intestinal tissues, increasing the expression of TGF-β, and decreasing the number of Th17 cells in each EBN dose group. These findings suggest that EBN has a protective effect on DSS-mediated colitis in mice, mainly by restoring the Th17/Treg cell balance.

“…[1] Recently, the classification and identification of specific compounds in food have also led to the identification of its origin and authentication studies. [2][3][4][5] Knowing the origin of food is important for quality control, food traceability. It ensures consumer protection and fair competition in the food industry against fraudulent substitution and adulteration practices.…”

“…Physicochemical, proximate, elemental, fatty acids, triacylglycerol, sialic acid, saccharides, peptides, and amino acids have been used previously to classify EBN following its colorations, regions, production sites, and harvesting seasons, [16][17][18][19][20][21] but no report on EBN species origin except for recent study by Quek et al [4] For a holistic representation of the characteristics and properties of EBN, various important parameters and properties of EBN including the physicochemical properties, proximate content, antioxidant activities, elemental compounds, amino acids, nitrite, nitrate, and sialic acid often result in a very large sampling size, a very large dataset which is challenging for analysis and interpretation. The conventional univariate data analysis is inadequate in handling large dataset with highly complex food composition.…”

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.
