Abstract:
The physical, chemical and sensory characteristics of five raspberry cultivars ('Newburg', 'Taylor', 'Latham', 'Festival' and 'Boyne') harvested at the red-ripe stage were evaluated at harvest and after 1, 6 and 9 months of frozen storage at -20°C. 'Newburg' was preferred for flavor (p<0.05) over 'Festival', 'Latham' and 'Boyne' and was significantly higher (p<0.05) in pH, % soluble solids and total sugars than 'Boyne' after 1, 6 and 9 months frozen storage. 'Boyne' was the least preferred for color and texture (p<0.05) at 6 and 9 months of frozen storage and was significantly less (p<0.05) red (lower chroma value) than the otner cultivars. Values for 'Taylor', 'Latham' and 'Festival' fell between 'Newburg' and 'Boyne'.
