Title:
REDUCING PARTICLE DISPERSION
Document Type and Number:
WIPO Patent Application WO/2023/048002
Kind Code:
A1
Abstract:
Provided is a reducing particle dispersion that achieves a high level of both preservative performance and oxygen reduction performance (oxygen absorbing ability), exhibits said performance in a continual manner (sustained-release) without adversely affecting other ingredients or the like, and has excellent dispersion stability. Examples of a reducing particle dispersion according to the present disclosure include a dispersion in which reducing particles that contain, as a main constituent, at least a polymer having, in a repeating unit, a structural unit represented by general formula (I) and that, for example, encapsulate at least one reducing component selected from group A are dispersed in water. [In formula (I), R is an alkyl group having 2-8 carbon atoms.] Group A: polyphenols, copper chlorophyll, flavonoids, anthocyanidins, dibutylhydroxytoluene, and butylhydroxyanisole. The reducing particles preferably encapsulate a preservative component together with the reducing component.
