Milk protein concentrate-based microencapsulation wall material and microcapsules

A microcapsule, comprising:

• a wall material, and
• a core material,
• wherein the wall material comprises a pretreated milk protein concentrate (MPC),
• wherein the core material comprises one or more of vitamins, unsaturated fatty acids, probiotics, vaccines, and essential oils;
• and
• wherein the pretreated MPC is prepared by subjecting the MPC to any one or more of the following:
• a) stirring ion exchange resin with the MPC,
• b) adding an acid to the MPC, wherein the acid is selected from one or more of hydrochloric acid, sulfuric acid, acetic acid, and glucolactone, and then subjecting the MPC to ultrafiltration, and
