摘要

A composite gel comprising: a) a dispersed phase comprising lipid droplets or particles; b) a continuous phase aqueous matrix comprising a pH ranging from about pH 4 to pH 9, and one or more cross-linked proteins; and, c) supplemental constituents; wherein the dispersed phase is embedded within the continuous phase matrix; whereby supplemental constituents or lipid droplets, suitable for ruminant ingestion, are protected against degradation, modification, or removal during passage through a rumen, and wherein the composite gel is without substantial aldehyde cross-linking. Also disclosed is methods to make and use the composite gel.
