Study about Nano Polyphenol: Biomaterial in Functional Food and Its Preparation

Polyphenols are diverse in structure and bioactivities, found in all plants and some animals, and include lignin, flavonoids, polyphenols, phenolic acid, and stilbenes. They are appreciated in antioxidant, anti-cardiovascular and application of them for humans, wherein polyphenol use for baby and pregnant woman still have numerous questions, simultaneously nano polyphenols are of great interest in recently. Hence, the chapter focused on polyphenols (define, classification, structure, and resources), their activity and mechanisms (antioxidant and anti-cardiovascular), use for baby and pregnant women, and the preparation methods of nano polyphenols (ten extraction methods of polyphenols and eleven methods of nano polyphenol preparations). Nanopolyphenols are necessary for future functional foods and medicine, for humans against disease and aging, but limited to use in pregnant-trimester women and children under 18 years old.
