Abstract
Raspberry (Rubus idaeus) fruit have high anti-cancer potential in animal and in vitro models.
There is much interest in quantifying total antioxidants, as well as specific compounds, to eventually be used to breed new cultivars that have improved human health properties.
Raspberry fruit of 64 genotypes were harvested for two seasons from Washington and New York locations.
Fruit were analyzed for soluble sugars, titrateble acids, pH and phenolic compounds.
Total anthocyanins ranged from 0 to 400 mg/100 g in yellow to black raspberries, respectively.
Total phenolic content ranged from 300 to 700 mg/100 g and FRAP values from 15 to 50 µmol trolox equiv/g.
Total phenolic and FRAP values were highest in black raspberries but yellow fruit were as high as many of the red raspberries.
Fruit composition and berry size also showed large variation among genotypes.
This study demonstrates the wide range of antioxidant values and phytochemical content in raspberry germplasm that can be used in breeding programs which are targeted towards developing functional foods.
