Chemical Characterization Of Wild Maine Cranberries, Dolly Jean Watson

Electronic Theses and Dissertations

This study was conducted to analyze wild Maine cranberries for anthocyanin (ACY), anthocyanidin, organic acid, L-ascorbic acid, and moisture content. Cranberries were analyzed in both the fiesh and fiozen states. Analysis for ACY and anthocyanidin content was performed by High Performance Liquid Chromatography (HPLC) and Capillary Electrophoresis (CE); organic acids by HPLC; and L-ascorbic acid (L-AA) and moisture by AOAC methods for titration and drying, respectively. ACY results showed similar qualitative profiles for all cultivars except one where no detectable ACY were present. Four major peaks and two minor peaks were detected, which have been tentatively identified as the galactosides ...
