Abstract:Consumer demand for pomegranate juice has considerably grown, during the last years, for its potential health benefits. Since it is an expensive functional food, cheaper fruit juices addition (i.e., grape and apple juices) or its simple dilution, or polyphenols subtraction are deceptively used.
Keywords:Pomegranate juice  Filler juices  Dilution  Antiradical scavenging activity  UV&ndash  VIS spectroscopy  Design of experiments  Multivariate analysis
