“…Our assay demonstrated that trapping of free radicals is one potential mechanism employed by antioxidant peptides present in the EBN hydrolysates. This mechanism was also reported in other studies using alkaline protease, Alcalase, and papain for EBN hydrolysis [ 11 , 12 , 39 , 40 ].…”

“…Also, Figure 3 (c) displays the inedible materials that are successfully separated from the bioactive EBN SiaMuc-glycopeptide. From our preliminary study previously, the EBN by-product has a high recovery yield of 89-99% with the use of enzymatic hydrolysis (Noor et al, 2022). This finding indicates that the current study has a lower recovery yield in comparison.…”

“…Since the study of EBN co-product is a new direction for the edible bird's nest industry, information on this eco-sustainable research is scarce, and only a few were reported. For example, Noor et al (2022) have reported a nutritional content of EBN co-product with protein content (54.29-56.57%), carbohydrate (18.98-20.77%), mineral (2.31-10.70%), and fat (0.43-0.80%). Surprisingly, the fat content of the EBN co-product was revealed to be higher when compared to the cleaned EBN.…”

“…Commonly, this so-called "waste" is disposed of like normal rubbish with the landfill method. However, within this EBN "waste" itself, there is an abundant amount of valuable glycoprotein that remains trapped and tightly attached to the inedible materials (Noor et al, 2022). This phenomenon happens naturally when the swiftlets build their nest using saliva which is spit to the wall of the nesting building such as the cave.…”

Edible bird’s nest (EBN) is the dried salivary secretion of swiftlets during the breeding season. The widely consumed EBN for its highly unique nutrients has contributed to a high demand for international exportation. However, the processing of EBN to remove inedible materials (i.e. sand, dust, feathers) has contributed to several wastes. The disposal of this waste is hazardous to the environment and a waste of value due to abundant sialylated-mucin (SiaMuc) glycoprotein attached in the impurities. This “waste” is the processing co-product of EBN. Therefore, this study aimed to recover SiaMuc-glycoprotein in EBN co-product (EBNco-P) in the form of bioactive SiaMuc-glycopeptide. Through enzymatic hydrolysis, an eco-friendly alternative to transform insoluble SiaMuc-glycoprotein in EBNco-P into soluble bioactive SiaMuc-glycopeptide, valuable nutrients are separable from the impurities. Previously, through our research, this biotechnology has been applied to cleaned EBN. The research finds that the enzymatic hydrolysis of EBN that produces EBN glycopeptide has led to bioconversion into a high-grade product with enhanced nutritional bioavailability and functionality. Similar results are also revealed in the analyses of cleaned-EBN and EBN co-products. Whereby, the result revealed that the optimum hydrolysis period was at 90 min, in which the DH and enhanced solubility indicated a complete breakdown of glycoprotein into bioactive glycopeptide. This result is in line with the physicochemical analysis result. The hydrolysis has significantly decreased (p≤0.05) the EBN protein content, while the levels for peptide, glycopeptide, polysaccharides, and sialic acid showed the opposite. This study may contribute to broadening the EBN product development in terms of nutraceutical functionality. With the availability of low-cost EBN co-products, this study is beneficial not only scientifically, but also to the consumers, commercialization, and industrialization.
