| Summary: | The aim of this study was to evaluate the protein content and antioxidant activity of instant and raw Edible bird’s nest (EBN). This study was conducted using two types of EBNs, which are instant and raw samples. All EBN samples were extracted via three types of extraction method, namely, salt, alkaline, and hot extractions. Lowry’s method was used to analyze protein content and the antioxidant activities were analyzed via free radical scavenging assay 1,1-diphenyl-2-pycrylhydrazyl (DPPH), total phenolic content (TPC) assay and ferric reducing antioxidant power (FRAP). This study showed that the highest protein was 2165.90 µg/mL obtained from raw EBN extracted via alkaline solution. In addition, it was also found that the protein concentration of raw EBN was higher compared to instant EBN for all types of extraction procedures. Results from antioxidant assay showed that there was no significant difference between DPPH and FRAP of both EBN. Moreover, TPC results showed that the there was no phenolic compounds detected via all extraction procedures. |
