Understanding of physicochemical properties and antioxidant activity of ovalbumin–sodium alginate composite nanoparticle-encapsulated kaempferol/tannin acid

Abstract

Ovalbumin (OVA) and sodium alginate (SA) were used as materials to prepare an OVA–SA composite carrier, which encapsulated the hydrophobic kaempferol (KAE) and the hydrophilic tannic acid (TA) (OVA–SA, OVA–TA–SA, OVA–KAE–SA, and OVA–TA–KAE–SA).
