Edible bird's nests (Bnest) collected from house and cave of eight provinces in the southern part of Thailand were characterised. Bnest from different locations had differences in Fourier transform infrared (FTIR) spectra and energy-dispersive X-ray (EDX) spectroscopy patterns but there was no distinctive difference in protein patterns. Crystallinity values of cave-Bnest from Phatthalung province (PL-C) and house-Bnest from Songkhla province (SK-H) (38.79% and 35.52%, respectively) were higher than those of other samples. PL-C and SK-H samples had different thermal behaviours, as determined by the thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Both samples were used for the production of Bnest beverage using the retort process (121 °C for 11min). Colour, soluble solid content, drained weight, and sterility were determined in both beverages. Average L*-value and soluble solid content of SK-H were higher than those of PL-C (P<0.05). Higher a* and...
