The physicochemical and antioxidant activity of Realfood’ hydrolysed bird nest (RHBN)

Year: 2025

Type: article

Abstract: Edible bird nest (EBN) is an exclusive natural product produced by swiftlet abundantly obtained in Southeast Asia and China. Edible bird nest contains a high amount of protein, which some proteins are sialylated. The protein content and sialic acid contents are reliant on the species of the swiftlet Due to the composition of the edible bird nest, this natural product is widely utilized as functional food and nutraceuticals. Our present study aims to characterize the edible bird nest obtained from Indonesia as well as characterize the value-added product Realfood’ hydrolysed bird nest (RHBN). RHBN was produced using the proprietary process implementing the highly pressurised heating. This study reveals that RHBN was produced from authentic edible bird nest. The authenticity was proven using a compositional analysis and proteomic study showing the used EBN has protein as major compound and considerable amount of sialic acid. Also, the typical protein of EBN was found in the present study. The processing of RHBN yielded oligopeptide (<6 kDa) and the swollen EBN with nano particle size was also found. The freeze-dried RHBN was proven possesses antioxidant activity using an in vitro (DPPH inhibition) with IC50 of 8.3 mg. Hence, we suggest that RHBN is a potential functional food from edible bird nest. Future studies on the investigation of specific bioactive peptides are suggested. Also, the in vivo study verifying the functionality of RHBN is highly suggested.
