Chemistry Professor Is Creating A “Molecular Footprint” Of Authentic Pomegranate Juice

November 29, 2010: 09:26 AM EST

A U.S. chemistry professor is analyzing pomegranate juice and juice blend products to determine whether they are the real deal, delivering the promised health benefits of antioxidants and other functional ingredients.  Cynthia Larive of the University of California, Riverside, is measuring levels of unique compounds in pomegranate juice to create a “molecular fingerprint” to that would help identify adulterated juice products. She and colleagues are measuring small-molecule metabolites in juices using nuclear magnetic resonance spectroscopy, liquid chromatography-mass spectroscopy and gas chromatography-mass spectroscopy. The three technologies determine levels of amino acids, organic acids, sugars, pomegranate pigment compounds, as well as health-producing antioxidant molecules unique to pomegranate juice. The research is being funded with a $50,000 one-year grant from pomegranate product maker Pom Wonderful.
