Enhanced stability and controlled gastrointestinal digestion of β-carotene loaded Pickering emulsions with particle–particle complex interfaces

We used large, rigid, and hydrophilic zein-propylene glycol alginate composite particles (ZPCPs) and small, soft, and hydrophobic whey protein microgel (WPM) particles to synergistically stabilize a Pickering emulsion for delivery of β-carotene.
