| Summary: | Edible bird’s nest (EBN) is a salivary secretion of swiftlets which consist of protein and carbohydrate rich glycoproteins.
This natural ingredient is very valuable, nutritional and medically valuable. The EBN industry have grown rapidly and
benefited the Malaysian economy, hence, it is viewed seriously and it is actively supported by the government. This
review discusses the progress and development of EBN industry as well as the R&D activities and endeavours especially
that which involves deriving peptides with biological activities from EBN and its by-product sources. Many studies
have documented the therapeutic properties of EBN such as antiaging, antiviral, antioxidant, and antihypertensive.
Studies have also been conducted to produce glycoprotein hydrolysates from EBN through enzymatic hydrolysis,
and findings showed that these bioactive peptides increase solubility as well as antioxidant and antihypertensive
activities. Enzymatic hydrolysis breaks long protein chains at specific sites and releases amino acids and small peptides
with lower molecular weights. The EBN hydrolysates produced can improve bioactivity and overcome insolubility and
low absorption of EBN prepared and consumed through traditional means. Further studies need to be carried out to
optimise EBN glycoprotein hydrolysates production as well as maximising their bioavailability and efficacy in the human
gastrointestinal system. In addition, EBN by-products produced during EBN cleaning process should be fully utilised
to recover the high-value glycoproteins, while reducing pollution and wastage. By enhancing R&D activities of EBN,
bioactive glycopeptides produced from EBN may become an important functional food ingredient for various uses and
innovative value-added products in the future. |
