摘要:
The present invention is directed to a specific egg yolk antibody, which substantially has antibody activity against a particular antigen, produced by a process comprising of supercritical gas extraction from an egg yolk of hens immunized with the particular antigen, and to a process of producing such a specific egg yolk antibody. The present invention makes it possible to easily and cheaply produce a specific egg yolk antibody which substantially has antibody activity and sufficiently reduced levels of the color, odor and flavor of egg yolk. Also, the specific egg yolk antibody of the present invention is good in oxidation stability during storage and excellent in fluidity for the food processing.
摘要:
The present invention is directed to a mehtod 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.
