Abstract: The development of milk functional foods including health-promoting green tea polyphenols represents a challenge for the food industry since the formation of protein-polyphenol complexes may affect both protein technological properties and polyphenols biological activity. The present work aimed at the characterization of complexes formed between green tea polyphenols and either β-lactoglobulin (β-lg) or caseinomacropeptide (CMP), as well as to evaluate how this complexation may impact on protein gelation and polyphenol antiproliferative activity against tumor cell lines. Particle size and charge of protein-polyphenol complexes depend on protein nature and pH. At pH 6 they had the smallest size and were soluble. The presence of polyphenols accelerated the gelation of both β-lg and CMP, and mainly affected viscoelasticity of β-lg gels. Polyphenol complexation by proteins did not inhibit its anti-proliferative activity. Moreover, they exerted a better performance on some particular tumor cell lines. © 2012 Elsevier Ltd.
