Abstract

This paper reports preliminary characterization of bird’s nest. The characterization include the morphology studies, proximate analysis, amino acids profile and antioxidant capacity. Microscopical characteristic of bird’s nest was examined under optical microscope. Amino acids were separated using thin layer chromatography (TLC). Amino acids profiles were then studied. Antioxidant capacity was determined from Ferric Reducing Antioxidant Power (FRAP) assay. The microscopical features of prism crystals and cluster crystal were observed in raw and extracted bird’s nest respectively. Proximate analysis showed that raw and extracted bird’s nest contained 38.98% and 42.16% protein respectively. The moisture and carbohydrate contents ranged between 13.66-36.85% and 17.20-39.68% respectively whereas fat and ash contents ranged between 1.00-1.50% and 3.50-5.50% respectively. FRAP analysis showed that raw bird’s nest contained higher antioxidant capacity compared to extracted bird’s nest with respective FRAP values of 4.711mM and 0.611mM. Arginine, praline, serine, glycine, glutamic acid, valine, phenylalanine, threonine, tyrosine, trytophan and aspartic acid were detected in raw bird’s nest. For extracted bird’s nest, glycine, glutamic acid and tyrosine were hardly detected. In general, bird’s nest is a rich source of amino acid.
