Process for Isolating Osteopontin and Glycomacropeptide from Whey

This document is a new patent application (US20260085099A1) filed with the USPTO, detailing a novel process for the isolation and purification of osteopontin (OPN) and glycomacropeptide (GMP) from whey or whey-derived liquids. The described method involves absorption onto a monolithic chromatography column, optional washing, and subsequent elution using controlled changes in salt concentration and/or pH.

While this is a patent application and not a regulatory rule, it signifies potential innovation in dairy processing. Companies involved in dairy ingredient extraction or functional food development should be aware of this patented technology. Compliance officers in the food manufacturing sector may note this as a development in intellectual property within their industry, though it does not impose immediate new regulatory obligations.
