Abstract
Quail egg yolk liquid was used to investigate the technology of quail egg yolk powder. The results showed that hot air drying and microwave drying are not suitable for the preparation of quail egg yolk powder. The optimum spray drying condition for quail egg yolk liquid: the feed temperature of 50℃, feed flow rate of 8mL/min, entering wind temperature of 180～200℃, spinning speed of 15000～18000r/min. The optimum condition of vacuum drying for quail egg yolk liquid: vacuum 0.06MPa at 50℃. Cold drying for quail egg yolk liquid is conducted as follows: thickness of quail egg yolk liquid of 6mm, and drying pressure of 20Pa.
