Abstract

Commercially grown raspberry cultivars (Rubus idaeus L.) (Festival, Boyne, Nova and Killarney) and advanced selections (88-18, 88-117, 88-134, SJR942-7) from the University of Guelph and agriculture and Agri-Food Canada (AAFC) were evaluated for total antioxidant capacity, soluble solids content and acidity. The crude, hydrophilic and lipophilic antioxidant content of berries were measured using the Trolox equivalent antioxidant capacity (TEAC) method. Significant variations were observed among crude, hydrophilic and lipophilic antioxidant content of the different advanced selections. Selection 88-18, had the highest crude, hydrophilic and lipophilic antioxidant capacity, while SJR942-7 had the highest soluble solids. The study shows the mportance of genetic background in determining the antioxidant potential in raspberry and the possibility of developing new lines rich in phytochemicals.
