Spray drying is a useful method for developing
egg process and utilization. The objective of this study was
to evaluate effects on spray drying condition of egg white.
The optimized conditions were spraying flow 22 mL/min,
feeding temperature 39.8 C and inlet-air temperature
178.2 C. Results of sulfydryl (SH) groups measurement
indicated conformation structure have changed resulting in
protein molecule occur S–S crosslinking phenomenon
when heating. It led to free SH content decreased during
spray drying process.
