Abstract
The invention relates to the production of compositions containing IgA for use as a food additive. More specifically, it relates to a process to prepare an IgA-enriched milk product extract composition and to such compositions.
Claims25
A process to prepare an IgA-enriched milk product extract composition including IgA and IgG extracted from milk product, wherein the relative IgA to IgG content is increased compared to that in the milk product, which process includes:
- providing:
- a source of milk product;
- a cation exchange resin;
- and
- a mobile phase;
- contacting the milk product with the cation exchange resin such that IgA is preferentially adsorbed thereon compared with IgG;
- eluting an IgA-enriched fraction from the cation exchange resin with the mobile phase;
- and
- collecting the eluted IgA-enriched fraction.
6 more elements
An IgA-enriched milk product extract composition wherein the IgA to IgG ratio is at least 1:8.
