摘要：
The present invention is directed to a method for producing crude sialic acid, comprising hydrolysis of a delipidated egg yolk and a method for producing high purity sialic acid, which comprises desalting a solution containing sialic acid obtainable by hydrolyzing a delipidated egg yolk, adsorbing sialic acid to an anion exchange resin and then eluting said sialic acid.The present invention makes it possible to produce and purify sialic acid from delipidated egg yolk on an industrial scale.
