The eggs are disinfected with alcohol and the egg yolk is aseptically collected in an Erlenmeyer Flask. The collected yolk is injected into a powder dryer to gather yolk powder. The injecting temperature of the powder dryer is 140deg.C and the releasing temperature is 72deg.C. The dried powder weight per 1ml vol and the moisture content of the egg yolk are 0.38g and 2%, respectively. The value of an antibody is rarely changed before and after the drying.
