The present invention relates to a processing method for preserved quail egg in which the heavy metal ions of lead, etc. are not contained. Its method is as follows: (1) a flavouring liquor is prepared by using caustic soda, edible salt, water and tea dust; (2) the quail egg is soaked in said flavouring liquor for a certain time, and then taken out; (3) the egg is cleaned with cold water to remove dirt on the egg shell surface, and then is dried in the air; (4) the waxing temp. is controlled, and the egg shell is paraffined to form a layer of paraffin film; (5) and the paraffined quail egg is stored at room temp. for a certain time, so that the invented product can be obtained. The advantages of said method are that the invented product doesn't contain the heavy metal ions of lead, etc. and the caustic soda is substituted for mixed liquor prepared by using quicklime and soda, and the alkaline concentration is easily controlled, and its storage time is long, etc..
