In this book, the binding efficacies of several antioxidant polyphenols resveratrol, genistein and curcumin with milk proteins, ¿-lactoglobulin, ¿-casein and ¿-casein were compared in aqueous solution at physiological conditions. Structural models showed that polyphenol bindings are via hydrophilic, hydrophobic and H-bonding contacts with curcumin forming more stable conjugates. The order of protein binding was ¿-LG>¿-casein>¿-casein. The loading efficacy was 30 to 50% for these polyphenol-protein conjugates. Polyphenol binding induced major alterations of protein conformations. Milk proteins are capable of delivery of these dietary polyphenols in vitro. |
